So, following on from this thread:
/showthread.php?t=6275 (http://www.amibay.com/showthread.php?t=6275)

I've finally got round to giving my A3000 some attention:

Shiny new sockets installed, courtesy of a friendly Solder Tech L10 at work.

It's bathtime for three lovely ladies! Agnus, Denise and Paula share an acid-bath in some lemon juice.

Old chips, new sockets!

An A3000 motherboard in all its glory, after all the chips have been replaced.

And does she work? HELL YES! 2MB Chip and 3.5MB Fast (The other 0.5 Fast will have been MMU'd out for the superkickstart image)

http://www.proggle.net/%7Eandrew/download/A3000/sysinfo.jpg
And finally, the obligatory Sysinfo shot. Everyone loves these, right? Interesting that she's 1.03x an A3000. Clearly something's a little nippier than on a normal A3000.

Next stage will be some work on the case. The old girl has been battered to hell, poor soul. I'm thinking maybe a respray in black. What do you guys reckon? More photos as and when I next get a chance to give her some attention!

I know the feeling, mate. It's taken me months to get round to this, but I'm glad I have, and I'm overjoyed that the old girl has sprung back into action. I was worried for a while that she might have been a lost cause, but some new sockets have given her a new lease of life!

Andy,

Good it is going! In black it won't be original. I would not do it, but hey it's youre computer, if you like it that way...

Some people on here do it with there A12000, but that is a more "stock" unit to play with I think. I have one A500 tower planning in gas pipe red.. = out of original case but can be put back

Soaking the chip in Lemon Juice? Does that not hold too much sugar? I always use cleaning vinegar to clean boards. Cleaning vinegar has no added flavouring. Maybe a little like distilled malt vinegar (the clear one, not the brown one :) )

All I can tell you is that I used lemon juice and seemingly it's done the trick. To be fair, I think the Amiga custom chips are a darn sight tougher than folks give 'em credit for :-)

The A3000D is one of the best looking amiga cases, . To me anyway. Some day, I will own an A3000D. Congrats on the nice work.

Regarding the case.. as Zetr0 would say, black is one of the hardest colours to get right. You will have to use some vinyl dye on the plastics to keep the texture and then standard black paint (satin) on the metal case. No gloss imosho.
But if it was my A3000D, and I only had one A3000D then I would have to paint it as close to original as possible.

Now you can change your signature: "A3000 - Still needs work..." or do you have other work to make inside? :)

The case needs some love, since it's bashed up pretty bad. Also my A4000 has a Super Buster -11 coming, the -09 that I remove from the A4000 will probably replace the -07 that's currently in the A3000.

Next post will be some case photos!

My 3000, which died in 1997, has had so so much attention to try and fix including new sockets, etc, but still is dead. I shall one day return to it, and fix it: this thread has given me hope :thumbsup:

Top corner:

As you can see, she really has been through the wars, poor thing. So, she really does need some attention on the case. So, I was originally thinking black would be quite nice. If she'd been in good nick, I'd never have considered respraying, but given she's in such a bad shape and needs a respray one way or the other, I thought I might go for something a bit different. So, what do you guys reckon, now that you've seen the extent of the damage?

It's OK, Tahoe; Andy is using the right stuff as I advised him to use it.

Lemon juice (or more correctly, Citric Acid) is used quite widely in metalplating and engineering as a metal brightener, especially for Aluminium and it's alloys. I saw it used extensively at BNFL Springfields, for brightening and cleaning Al/Mg alloy Magnox fuel cans for Wylfa nuclear power station - they always came out super shiny!

Andrew, what about doing just Retr0bright on the front fascia and spray the original colour on the metal case parts?

An A3000 is a beauty machine, please quit the idea of changing it.

Oh, and a bit of sandpaper on the indentations can make it look less battered.

Well, I've given the old girl the acid test today. She's been playing Frontier: Elite II for the last four hours and is still going strong. I've been amazed at how much nippier it feels than on my other Amigas. Fantastic stuff!

Now, back to selling computers (Amigas of course) to desperate people at the Galileo spaceport!

Andy,

If black is a no-go, nip down to Halfords or a local motor factor and get some Austin Rover Old English White acrylic aerosol paint. It's the best match for PC case beige / off-white that I've used to date.

A quick respray of the metal case and Robert is your father's brother.

Cheers, Merl. That might be for the best. I fear that if I spray the A3000 into black, rkauer might jump on a flight to the UK and come round and beat me to death with a club.

Meanwhile, I'll get back to Frontier. I just upgraded my ship, but forgot to buy an autopilot. Manual docking is such a pain in the proverbials!

Yes, considerably nippier. I suspect that may be down to the chip speed, which is almost twice that of the A2000.

Well well, what can I say? I am really happy for you buddy, been following this thread closely and it all sounded dire but this is not what I expected. You have made me slightly envious actually, have always wanted a 3000. :)

Oh as for the case, I'd take it apart and clean what you can with soapy water, use some all purpose spray polish and retr0bright it. If the metal casing is too bad then I'd get that to the bare metal and spray that to match the plastic. It would be well worth the effort me thinks. :)

the idea of silver/chrom trimmings is nice.

I have always felt that Amga's should be 2 tone - much like the keyboard =)

with black its possible to breakup all that area with asceticially engineered colouring of silver/gold/chrome =)

So, courtesy of the rather awesome Amiga-Digital (http://www.amibay.com/member.php?u=454), I am now the very happy owner of a SIMM-folie for the A3000.

http://www.proggle.net/%7Eandrew/download/A3000/SIMM-folie/top.jpg
http://www.proggle.net/%7Eandrew/download/A3000/SIMM-folie/bottom.jpg

For those who don't know, this is one of those ZIP to SIMM adapters that allows you to use cheap PC 72pin SIMMs in an Amiga 3000, instead of those rarer ZIP DRAM modules.

http://www.proggle.net/%7Eandrew/download/A3000/SIMM-folie/before.jpg
So, there are the existing ZIP modules. A whopping 4MB there! So, let's tear them out. :D

http://www.proggle.net/%7Eandrew/download/A3000/SIMM-folie/zips.jpg
And there they go. I'll pop those aside, I have a plan for them later...

http://www.proggle.net/%7Eandrew/download/A3000/SIMM-folie/after.jpg
And there's the module, installed in the ZIP sockets. It was an absolute pain to get it in, but now it's there, I'm satisfied! The big win that this adapter provides is that it's not physically incompatible with a CPU card, so I can still shoehorn an A3640 in there (At least in theory. A3000s don't like CPU cards much!)

So, let's fire the old girl up! First time, my metakick ROMs said "No memory to map Kickstart into" so I had to go back inside and bash even harder on the board to make it fit in the sockets (Those ZIP sockets are evil) but we got there in the end and I booted something:
http://www.proggle.net/%7Eandrew/download/A3000/SIMM-folie/workbench.jpg
That's what we like to see! A nice 16MB of FastRAM, just as an Amiga 3000 should be!

http://www.proggle.net/%7Eandrew/download/A3000/SIMM-folie/sysmem.jpg
Sysinfo agrees, 15MB of RAM (The last MB is MMU'd out for the Kickstart image)

Of course, there is one hit you take with these:
http://www.proggle.net/%7Eandrew/download/A3000/SIMM-folie/sysspeed.jpg
The performance isn't quite as good, since I've replaced Static Column ZIP RAMs with slightly slower Page Mode SIMMs. Still, that's a healthy 4.39 Mips and as I plan to stick an A3640 in there it becomes irrelevant, since the 68040 doesn't support burst mode. As such, the Static Column ZIPs wouldn't be taken advantage of anyway.

So, where to next? When I've got some more Amiga cash floating around, I plan on trying to source a second floppy drive with the correct A3000 furniture (The fat eject button and the appropriate LED) and a hardware Kickstart 3.1 ROM, then eventually I'd like to stick in an A3640 and have an A3000/040 with 16MB RAM and 4GB hard disk.

Oh, and I need to sort out the cosmetics of the old girl, but that involves settling on a colour scheme, so I'm holding off on that for now!

Thank you for your kind words.

As for the A3000, they do crop up from time to time. I swung this one on the Evil Bay a few months back for what I considered to be a very reasonable price. I've found that patience is the greatest virtue of getting affordable Amiga kit, just keep looking and one will come along soon enough. :-)

Thanks Andy. I always wondered if those Simm Adapters were detrimental to the A3K's performance. I know it's only slight, but that's still a 10% speed hit. ;)

Charlie

Indeed. I've been reading around and I was expecting that 10% hit. The issue comes down to Static Column ZIPs supporting burst mode access, which Page Mode ZIPs don't. Of course, all 72-pin SIMMs are Page Mode also. (I don't believe you can get Static Column SIMMs)

It's essentially true of the A4000/030, too. You get about the same performance as an A3000 with Page Mode RAM (Since the A4000 uses Page Mode SIMMs)

Still, the biggest advantage of this particular adapter is that it leaves enough space for a CPU card. I'm thinking an A3640 is probably adequate for my needs. As I understand it, the 68040 doesn't support Burst Mode, so there'd no longer be any advantage to Static Column RAM chips anyway.

Probably because it's 3.18, the last one was 3.24.
And within the history file:



There was an error in the string for 25Mhz Amigas and this was forcing it to show as "25000". This has now been corrected and shows correctly as "25.00"

OK, so next on the list of A3000 Things To Do: Fix the RTC.http://www.proggle.net/%7Eandrew/download/A3000/corrosion.jpg

I'd like to stick a lithium coin battery on there, but it's looking pretty nasty down there at the moment :( Anyone have any advice/recommendations to what I do first. I don't just want to shove a coin battery over that bit of exposed PCB. It probably needs lacquered at least. If so, what should I buy to lacquer it with? :-)

Merlin
12th October 2010, 14:00
Andy,

I'd go for coating it with a two-pack epoxy adhesive like Araldite, for a couple of reasons.

1. Araldite is an amine cure epoxy, so the amine hardener used will provide some ongoing protection against further acid corrosion of the copper from the battery leakage.

2. Epoxy adhesives are thermosetting, so they don't melt when heat is applied. If you were to epoxy glue a wire link through the hole in the board, you could solder to that wire without the adhesive melting and making a mess.

3. It's fluid enough before curing to be brushed onto the surface as a thin coat.

4. Epoxy is very close to the composition of the mainboard substrate, so it will be compatible and stick like the proverbial.

That's my call as a chemist anyway.

:thumbsup:

This got me thinking, (usually a bad thing :lol:) Has anyone considered......:unsure: chroming their Amiga?

Maybe this is heresy (in fact I am pretty sure it is :roll:) and would likely be too expensive, but I found a firm on the net that claims it can chrome any plastic in a variety of different finishes, eg normal chrome, bronze or gold. I have no idea what they would charge to do the front on a big box Amiga, individual keys would be tricky to do too, not to mention how you would go about putting letters back on them. Anyways, here a link to one in the UK http://www.qppltd.co.uk/index.asp

I think they are mainly doing things for the automotive industry. Renovating plastic grills on classic cars and such like.

Ive often thought about chrome plating one of my big box Amigas. Would look awesome.

Indeed you can chrome plate plastic - they usually soda blast the plastic, coat it in a metal rich paint, and then electroplate the paint coating with chromium.

If done properly, works well, looks great and lasts forever. if NOT done properly it will peel off in sheets and looks terrible.

So you need to be careful who you get to do it.

I think an A3000 in black would be awesome, but its the hardest to pull off -


you will need some stenciling / foil decales to make it happen.

This got me thinking, (usually a bad thing :lol:) Has anyone considered......:unsure: chroming their Amiga?

Maybe this is heresy (in fact I am pretty sure it is :roll:) and would likely be too expensive, but I found a firm on the net that claims it can chrome any plastic in a variety of different finishes, eg normal chrome, bronze or gold. I have no idea what they would charge to do the front on a big box Amiga, individual keys would be tricky to do too, not to mention how you would go about putting letters back on them. Anyways, here a link to one in the UK http://www.qppltd.co.uk/index.asp

I think they are mainly doing things for the automotive industry. Renovating plastic grills on classic cars and such like.

Chroming plastic has been around A long time but it will start pelling
with time and rubbing will also speed that up some..
Now do the metal body in chrome and the plastics in glossy black that
would look nice!!!:thumbsup::thumbsup:

Nah, if done properly it will never peel. I have some gear plastic chromed properly and the they have actually created a rough etched surface by blasting. This is a perfect substrate for adhesion.

As is inevitable, things never happen when I hope they will. Still, some weeks later, I finally shoehorned some more shizzle into my A3000:

http://www.proggle.net/%7Eandrew/download/A3000/3640simm.jpg
If you look closely, you'll see the Super Buster-09 that I pulled from my A4000. After upgrading the A4000 from -09 to -11 it seemed sensible to use the surplus -09 to replace the -07 that this A3000 shipped with.

Of course, there's something else there. Is that a SIMM adapter and an A3640 wedged into the same A3000? Oh, yes it is! The SIMM-folie is true to its word, it sits quite happily out of the way of the A3640. Thanks to the rather Jawsome Mr. JuvUK for the CPU card! :)

So, I swap J100 and J104 to EXTCLK, whack in the CPU card and hit go. What are the odds on it working first time?

http://www.proggle.net/%7Eandrew/download/A3000/sys040.jpg
YEAH BABY! That's what I'm talking about! 18.82 Mips of 68040 POWAH in a humble desktop A3000! With a full whack of 16MB Fast on the motherboard, this is one mean little beastie!

Sadly, even with the fan removed, the heatsink is still too tall for me to fit the A3000 back together again, fortunately the rather awesome Zetr0 has come to my rescue with a low profile heatsink and fan, which is on its way to me imminently!

I whacked in the 60MHz Xtal and tried again, but alas! It was not to be, black screen and nothing. Swapping back to the 50MHz Xtal and everything sprang back into life again. My guess is the A3000 chipset doesn't like being driven at 30MHz, I'd guess the SCSI subsystem is the most likely candidate to protest. Still, 25MHz was all I was ever aiming for, anything more would just have been a bonus.

So, what's left to do? Well, heatsink first of course. Next, LTAC has sent me a replacement SCSI chip to replace the buggy WD chip that the miggy shipped with. I'm hoping that'll straighten up some weird issues with external SCSI devices. It's only a few minutes to swap that in, but it'll wait for another day. Finally, jvdbossc has also sent me the bits I need to solder in a coin battery to fix the clock. Once that's done, we're basically there! The only other thing I might do is swap the 5400RPM SCSI disk for a 7200RPM one instead.

Oh, and once all that's done, We can go back to the black vs. beige debate... ;)

Thanks for reading along and sharing my little A3000 adventure. I hope you've enjoyed reading it as much as I've enjoyed writing it!

Awesome work Andy! ;) I knew it would be a tight fit but was confident it would work. You probably need clock 90 mod for 30 Mhz. Ask rkauer he should know by now! Now he needs to finish PCB layout for 16 meg SIMM mod. I already did 3/4 of the work. Should I have to do everything? (hint)

Update time!

So, I've had a really rather productive afternoon/evening in the company of my beloved A3000. Here's the update (With obligatory pr0n, of course!):

http://www.proggle.net/%7Eandrew/download/A3000/2011-06-25/01-fascia.jpg
So, I took rkauer's advice and sanded down the dents and bashes in the fascia and they look a lot less pronounced as a result, definite bonus! Now I just need to retr0bright it to get it looking sharp again! It'll probably also need some sort of varnish or similar to cover up the sandpaper marks (although they really aren't too bad, it's just in certain lighting conditions you can see 'em). Oh, and on Merlin's advice, I'm gonna make a trip to Halfords for some Austin Rover Old English White. (Yeah, I made a decision, gonna try and restore this baby back to its original beauty!)

Anyways, cosmetics are fun and it's nice to make your miggies as sharp as you can, but let's face it, we're all hardware freaks and are far more interested in what's under the hood, so...

http://www.proggle.net/%7Eandrew/download/A3000/2011-06-25/02-hsf.jpg
Zetro's heatsink and fan arrived in the mail on Friday, so I got to play this weekend. Nipped out to town and got some thermal compound and attached this tiny little fella onto the '040. I also cut up a Molex-to-floppy power converter and soldered it on to the bare wires on the fan so I can power it from the A3000 PSU.

http://www.proggle.net/%7Eandrew/download/A3000/2011-06-25/03-hsf.jpg
Here it is, all installed and spinning its merry way round and round.

http://www.proggle.net/%7Eandrew/download/A3000/2011-06-25/04-hsf.jpg
Oh, and a gratuitous shot of it all up-and-running with some Sysinfo scores off to the right. As you can see, the whole thing is rigged up naked on the table. It'll all go back in the case when I'm happy it's all working.

http://www.proggle.net/%7Eandrew/download/A3000/2011-06-25/05-showconf.jpg
Showconfig tells me I've got a full-ECS Amiga with a full-core '040. Workbench tells me I've got 2MB Chip and 16MB Fast to go with it. These numbers make me a happy boy!

So, what else is there to do? Well, I've been having SCSI problems. The controller doesn't like anything on the external connector. Rumour has it that this is due to the buggy WD SCSI chip the A3000 ships with. Fortunately, LTAC comes to the rescue here with an AMD drop-in replacement that is free of those pesky bugs. Let's drop it in:
http://www.proggle.net/%7Eandrew/download/A3000/2011-06-25/06-scsi.jpg
Before->During->After. DIP swapping is a relatively painless exercise these days, although you do always have a bit of a struggle with new chips since their legs bend out too far!

Then another fire-up and make sure we haven't broken anything:
http://www.proggle.net/%7Eandrew/download/A3000/2011-06-25/07-scsiwork.jpg
Looking good to me! I did have a brief moment of panic when the hard disk wasn't detected, but that wasn't anything to do with the new chip, that was just me being a retard and not plugging the hard disk back in! I'll see how the external SCSI devices behave once I've been able to put it all back together.

Well, whilst I've got the motherboard out of the chassis, might as well implement this little circuit:
http://www.proggle.net/%7Eandrew/download/A3000/2011-06-25/08-drawing.jpg
This is the scrawl I made when I did the lithium coin battery hack on my A2000, I'm glad I hung on to it. Crucially, it shows you where you bung the diode in, and which way round it goes.

http://www.proggle.net/%7Eandrew/download/A3000/2011-06-25/09-battdiode.jpg
So, first up, let's attach the diode to the positive terminal of the battery. On this style of coin-holder, it was nice and simple to bend the leg up and solder the diode to the bent-up leg. (There are a few tricks you can apply, depending on which type of coin-holder you have. If you're interested in the coin battery hack, I'll be posting up detailed instructions in a separate thread in the near future).

Next, I wrapped a bit of electrical tape around the joint to keep it together and to stop it shorting against anything else on the Amiga motherboard. Then we solder the -ve terminal of the coin holder and the other end of the diode to their respective holes on the A3000 motherboard. De-soldering the remnants of barrel battery was a nuisance, but I'd learned from the A2000 and it didn't take nearly as long this time!

http://www.proggle.net/%7Eandrew/download/A3000/2011-06-25/10-battholder.jpg
A bit blurry, but you get the idea. Coin holder all installed and happy. Now we bang in a battery and thump 'go' once more. As ever, my good friend Sysinfo comes out to play again:

http://www.proggle.net/%7Eandrew/download/A3000/2011-06-25/11-clockfound.jpg
Woo! Clock found. My A3000 can tell the time again! To be sure, I set the clock, powered off for a few minutes, then powered on again. Result: All present and correct. Awesome!

Oh, and whilst I've got the multimeter and soldering iron out, I thought I'd check Speedgeek's hypothesis about my LEDs. Answer: He was spot-on (of course!). The tracks on the board had decayed, which was why the LED was no longer lighting. "Strike while the iron is hot" they say, and my iron was definitely still hot, so here goes with yet another patch-up repair:
http://www.proggle.net/%7Eandrew/download/A3000/2011-06-25/12-ledboard.jpg
Hmm, another blurry photo. Sorry about that, if I get a chance, I'll post up some better ones later. But you get the idea, solder on a jumper wire to bridge over the broken tracks on the PCB and AndyLandy said...

http://www.proggle.net/%7Eandrew/download/A3000/2011-06-25/13-ledswork.jpg
"LET THERE BE LIGHT!"

So, all-in-all, a really rather productive and successful day of hackery. At this point, we're almost done. I'm so very close to having a finished A3000.

I attempted the delay line hack on the A3640, but I just couldn't get the wire to attach to the delay line circuit and when I started to smell melting plastic, I decided it was time to call it a day on that one. It's not like I'm really all that bothered about clocking the CPU higher (although it would be nice to do). In all honesty, I mostly just wanted to prove that you can use an A3640 and a SIMM adapter at the same time.

I also passed on the INT2 mod. I don't need it as the A3640 doesn't have on-board SCSI, and given my failed attempt at the delay line hack (and the difficulties I had just soldering a jumper wire on the LED board) I decided just to give that one a miss.

So, all that remains is to retr0bright the fascia and re-spray the metal chassis, replace the cracked HDD LED (although it does work, it might be worth just going down the hot glue route instead) and then put it all back together again!

Thanks again for joining me on my epic A3000 adventure. We're on to the last stretch now, nearly there!

Running bare motherboards on the table has been a bad habit of mine for many years now. I've even got a couple of old AGP cards where I've removed the brackets so they can be used in an au-naturelle board.

As for the case, the plan is to retr0bright the front plastic fascia and re-spray the metal lid part.

Well, it turns out that whilst the battery circuit appears to be fine, the actual clock circuit is not. I powered on the A3000 this morning and it still thought it was 11pm last night! Anyone have any suggestions on what's going on there?

(I reckon some lemon juice has got into the pendulum and it's jammed! :lol:)

Tomse
26th June 2011, 14:04
seems that it doesn't get a signal from the oscilator/crystal.

when powered on, does the clock tick ?

if you check pin 17 (use pin 1, 8 or 10 as ground)
if it's 0V check C193 or C192, see if R193 measures around 100Kohm

check VC190 if that is shorted to gnd. it's a variable cap which could still have liquid inside thus being shorted to gnd.

Had teh same problem with my 3000D.

The thing i did where to turn of the amiga and mesured the DC voltage from the batteri step by step to the U190.

Found out that a track where cracked just before one of the resistors so i just soldierd a smal wire from the + on the batteri side to the resistor and now it woorks just fine.

I took the liberty to cut out the clock part from the schematics. Dont know if you need it but i post it anyway.

So, I attempted to investigate to what extent the clock wasn't working. Is it completely stopped, or just running slowly. Does it tick when the machine is on? What about when it's off.

The answer, it's mysteriously started working correctly! I haven't touched anything, but now it consistently shows the correct time. Bizarro, but I'm not complaining!

Great looking 3k Andy. Your a real technician.

The 3000 is simply the best amiga ever made, IMHO.

One quick hack you can do is clocking the 882 up to 50 mhz. I don't remember the details, but I'm sure the literature is out there somewhere.

I overclocked one 3k over 15 years ago and still works fine...

Cheer and terrific job.

Finally had a read of your journey, looks great! Any progress on your case?

Also, overclocking the A3640 is NOT a good idea. Especially in the A3000. It runs way to hot stock. I had one overclocked at 33MHz in my A4000D years ago and it would lock up my machine when it was hot. It would be worse in the A3000D.

Not done anything with it in a very long time. Real life caught up and I've had other projects to deal with, sadly.

As for the A3640, it's actually running an MC68040 33MHz CPU, under-clocked to 25MHz. Even if it was running at 33MHz, it'd still be cooler than the XC68040/25 that the thing shipped with. And it's got an active cooler on it as well, just for good measure. There's no risk of overheating CPUs here!

As long you make adequate cooling provisions (I have the large rectangular bed of nails heat sink + cooling fan) there is nothing to fear about overclocking an A3640 in an A3000D. In fact with the A3000 mobo limited to approx. 30 MHz most A3640 and 040's wont even come close to their physical limits. However, MC68040's are much better suited to the overclocking task*. ;)

Your big box Amiga could could be locking up for many reasons other than CPU overheating. For example, the PSUs usually have a negative temperature coefficient resulting voltage drop on the +5 Volt rail. Also, other hardware design bugs compound the problem making the system even more unstable with heat but if the CPU is overheating it's usually one of the easier problems to solve.

As far as cutting holes, case modifications or overclocking hacks, etc. go you should remember that nothing lasts forever! (i.e. Physicists have predicted the Universe will end in an infinitely vast cold dark haze of sub-atomic particles).

So, you can practice self deception about preserving your Amiga's for posterity or live your Amiga's lives to the max! I've already made my choice. ;)

Glad you have it working. Hope you get some nice use out of it...

I went on a very long, very painful, and very expensive journey with my 3000D. Now she is back and running perfectly well, she is where I wanted her to be for a very long time (bought her new in 91). She has the CS MKIII, CV64, Delfina Plus, Ariandne, phonepak, the latest chipsets and an SSD. She runs silent, very fast (for an Amiga) and cool. Playing MP3's, browsing the web, and looking at pictures all run without slowdown or hickups, not bad for a computer built in 1990! I borrowed a 4k for my kids to use, and it is a very nice box, but I have always had a soft spot for the 3000D...

I would replace the PALS with GALS and replace the PSU fan with a more efficient one to control the heat better. My system runs much cooler now. Lastly, I have a open area underneath it (Could put feet up a bit), the bottom gets hot, especially with PALS. One last item make sure everything is where it should be inside to help with airflow.

Good luck!

One last thought, is that I have heard the the DMAC 4 and Ramsey 7 help run the 3000 cooler. I have never ran a comparison, but you can keep you eyes open for them...

Well, after gaining some great advice from Zetr0 and johnim regarding SFS and ClassicWB 3.9, I decided it was time to give my A3000 something really nice!

http://www.proggle.net/~andrew/download/A3000/01-scadrive.jpg

That, my friends is an SCA SCSI hard disk. It's a Seagate 73GB, 10,000RPM drive. Can you say "overkill?"

An A3000 can't possibly manage to drive something as obscene as that, can it?

http://www.proggle.net/~andrew/download/A3000/02-partitions.jpg

Well, apparently it can! Look at all those juicy (and empty) 16GB partitions. I wonder what to do with them... I've added an entire WHDload collection and the MOD Anthology to the first one and it's not even full yet. And there are three more. Still, it does no harm to just have them there, you never know, I might get a super-efficient H.264 decoder for the 68040! :lol:

Next challenge is to work out how to physically wedge the disk into the case. With the SCA-80 to 50pin adapter board on the back, it's too long to mount in the HDD bay correctly. I think some kind of hackery is in order here...

No hackery needed, just use a bit longer screws and some large rings, while not using the bracket, or lose the 2nd floppy drive if you have the coverup.

In that case you can use the bracket, but the drive has to have sca80 adapter facing towards the front cover.

Yeah, I've had a look at some of those possibilities. I don't want to lose the second floppy drive particularly, but I guess it could go if I needed it to.

Losing the bracket might be the way forward. I'll have a poke about and see what I can manage.



That, my friends is an SCA SCSI hard disk. It's a Seagate 73GB, 10,000RPM drive. Can you say "overkill?"

Wanna race the 73GB 15,000RPM drive that lives in my A3000? :mrgreen: ;)

Hehe! I was rather dismayed to discover that from my collection of drives, I had the choice of either a 36GB 15,000RPM drive or a 73GB 10,000RPM one. I've gone for the bigger but slower one at the moment, but I might actually put the faster drive in, since I'll never even come close to using all that space.

The RPM of the drive won't matter, it's only more noise and heat :-D
These things have more cache on the drive than that your A3000 has in total, so it will never reach it's full throughput, not even with a CS.

To be honest, the scream of the 15,000RPM drives was one of the reasons I decided against it. They're pretty awesome, but as you say, everything about these drives is way overkill for what an Amiga can manage, even with a CSIII/PPC.

That is really amazing :) I hope it is really usable and does store data really to the full partition :Doh: I like to read this thread. To many A1200 / other stuff, while the A3000 has a lot to offer.

I had normal scsi drives from servers and indeed, they are not fit to serve an amiga, the noise, is not really desktop.:double At the best some good external device with some modern noise killing materials..

Yeah baby, that's right! My A3000 has the lid back on again! There are even a couple of Zorro cards in there, including my fancy-pants new X-Surf 3cc, courtesy of arnljot, and an A-Max Mac emulator board, which I've had kicking about the place for months. One day I'll actually get round to having a play with it!

Night all!

Put my hat in the ring for a race.

See how my trusty 3000D runs with it's CS MKIII with SCSI 3 tied to my OWC SATA 3 SSD drive via Acard 2000 SCSI/SATA adapter...

Replaced the power supply fan with a silent fan, now the beasty is a real sleeper. She is totally silent and real speedy...

One other bonus is after I replaced the PALS with GALS, she runs really cool...

Line em up...

Yeah, one day I'll take out a second mortgage so I can afford a CSIII. That would be awesome!

On the subject of replacing PALs with GALs, how/where do you get suitably programmed GALs?

It took me over 20 years to buy the MKIII, it was a bit of a treat to myself.
If I could be totally honest with you, if you could find a Warp Engine 3040 you would be totally happy. The difference between a Warp Engine 3040-040@40MHz (with 64 Megs local ram and SCSI 2 Fast) and a CS MKIII (with 128 Megs local ram and SCSI 3) is not really major.

I prefer the Warp Engine for many reasons:
1. You don't need the Int hack, it contains a jumper to connect to the chip. No solder or removing motherboard.
2. It fits perfectly. The CS MK III requires you to remove a bank of memory to screw it down and much pickier.
3. The WE is a tank, no worries. The MK III has a fragile socket for the 060 you need to be careful about.
4. Should be much more reasonable, but with the rarity of the 3040 I'm afraid it is probably almost as expensive as the CS MK III.

The Warp Engine is the best accelerator I have ever come across. That said the CS is faster, but the visible difference is not that impressive imho.

I bought the gals from Cosimo at Amiga.org. PM him there and see if he has any.

The Gals make a huge difference. With all the work I have done with my 3000D, it runs much cooler than my 4000D. I have found that even though the space is tighter in a 3000D, it moves air much better then a 4000D. The 4000D places the fan is a useless area in the middle of the box that doesn't get much exposure if you have a CD rom installed.

Take care Andy!

Once you've done it the first time, doing it again is easy peasy! One Amiga 3000, on the 'net and Googling for more Amiga 3000s.

In other news, my PC appears to be behaving itself once more, so I'm finally setting up a large hard drive for my A1200. That's soon to have a 40GB laptop IDE disk inside, ready for some WHDLoad goodness! But that's for another time and another thread...

I apologise for not reading the entire thread first but I am very interested to know - Where can I obtain an SCA 80pin to 68pin adaptor?

I will begin with googling, I did try fleabay but got a little stumped.

This is where I get my SCA80 to 68 pins from.
So these are useful on Cyberstorm MKIII/PPC.
http://www.ebay.co.uk/itm/SCA-80-ADAPTER-TO-68-PIN-ULTRA-SCSI-II-III-LVD-SE-/330432182060?pt=US_Drive_Cables_dapters&hash=item4cef4af72c

And this is SCA80 to 50 pins, so any Amiga 3000D/T, Warpengine 3040/4040, Cyberstorm MKI, Blizzard 2040/2060, GVP HC8+, Oktagon 2008 and so on.
http://www.ebay.co.uk/itm/SCSI-SCA-80-Pin-F-to-50-Pin-M-Internal-Adapter-K-/320597027825?pt=UK_Computing_Drive_Cables_Adapters&hash=item4aa5126bf1

I have bought 2 times from this seller, so save him in your account, postage is free, so it's best to order a few of them like 5 or 10.
Delivery is quite fast, so you shouldn't have to wait long.

Remember, and this is really important!
Buy an active terminator with it if you are using 50 pins!
So search ebay as: scsi active terminator
This has to be placed at the end of the line.

So for example:

http://www.amibay.com/picture.php?albumid=78&pictureid=2743
So in this case it's only a HDD setup, the end goes into a 50 pins scsi controller.

http://www.amibay.com/picture.php?albumid=78&pictureid=2742
9 out of 10 times the red line needs to be facing towards the power connector, but not with SCA80 adapters!
So do it like this!

Interesting you using lemon juice for cleaning the chips! How does it compare to ISO-propyl alcohol?


So, following on from this thread:

I've finally got round to giving my A3000 some attention:

And finally, the obligatory Sysinfo shot. Everyone loves these, right? Interesting that she's 1.03x an A3000. Clearly something's a little nippier than on a normal A3000.

Next stage will be some work on the case. The old girl has been battered to hell, poor soul. I'm thinking maybe a respray in black. What do you guys reckon? More photos as and when I next get a chance to give her some attention!

Lemon Juice isn't for cleaning it's to neutralise the battery acid.

You must then clean the board with IPA after :thumbsup:

Glad this has cropped up!

This week I've been trying to get hold of some white vinegar to neutralise some damage on an A500 expansion card for someone that kindly lent me the machine for other purposes. We can't find any. Been to the supermarkets and the health food shops. Health food place reckons their suppliers can't get any either.

So two questions, any idea where I could get some? Or alternatively, if I use lemon juice, excuse the ignorance but are we literally talking about buying some lemons and squeezing them??

Thanks.

You could squeeze a real Lemon if you like or just buy the bottled stuff you put on pancakes :D

What's the reasoning behind using lemon juice if you clean the board with IPA anyway? A good scrub with IPA and a rinse should remove any acid.

I've done some repairs where capacitors had leaked and started to corrode some traces, I just dipped in 99% IPA, scrubbed, rinsed with de-ionised water and allowed to dry completely (blowing with compressed nitrogen and oven heating works very well). I haven't seen any further damage, I'm pretty certain all the contamination has been removed.

I didn't think IPA neutralized the acid?

The danger of battery damage with the 3k is the middle layer of the board traps the acid and can cause problems long after the board has been cleaned...

What, the stuff in the lemon shaped bottle? Jif Lemon or whatever it's called? I always thought that was diluted and therefore no good. But to be fair I like neither lemons or pancakes so I'm no expert :lol:

The IPA won't neutralize it, but it will displace it, though you might need some elbow grease too. I'm not too convinced that acid could seep into internal layers as it's almost always a surface corrosion effect and the epoxy and fibreglass don't seem to effected by it. I've never seen any delamination due to battery or capacitor goo for example.

I just think the lemon juice might be unnecessary. It certainly doesn't seem to hurt anything though.

edit: Also, does citric acid really neutralize battery acid? That doesn't really make sense to me, but my Chemistry is pretty poor to be honest. I would've thought Baking Soda would do the job instead.

Iirc Battery 'Acid' is actually an Alkali, the lemon juice is mildly acidic.
Once you put the lemon juice on where the battery has leaked, it will froth a little, neutralizing the acid.
Used this on my 500's that had leaky batterys (500+ and a 4mb ram card with a battery)

That's interesting, thanks. :thumbsup:

I might ask someone with access to IPC standards to see if this is covered, I wonder if someone has determined if it's necessary to neutralize before cleaning.

That's exactly the stuff I used, Jif Lemon. It really brought up a shine on the corroded pins of the Amiga custom chips. The A3000 is still going strong, although I've not powered her up in a few weeks.

As folks above have said, the reason for the lemon juice is to neutralise the battery acid. Mild damage can probably be cleared away with IPA, but in this A3000, the battery had sprayed goo everywhere. Lemon juice reacts with the battery acid and makes some water-soluble salts that are easily washed away.

And yes, the term 'battery acid' is colloquial for the goo inside a battery. Even though most domestic batteries are alkaline ones, it's still often referred to as 'battery acid' :lol:

I'd be surprised if it's just sheer quantity, the original 1+1 configuration shouldn't really be a slowdown unless you're trying to run lots of stuff. I guess it's possible though, who knows.
