Yep, mines ice cold - you could quite happily lick it on a Summers day :)

But it sounds like a Jet Fighter and its on Stilts :Doh:
 
@Steve, your on a roll today aren't you mate HAHA! Go on, admit it, you've been licking it haven't you? :D

@paalrosen, thanks mate :)

Jokes aside, this XC 060 is stone cold to touch, even under full load - never gets warm. But I'm not sure I can live with the noise! I did put a manual speed control on it.

I didn't reaise though how loud the BPPC Fan and Fan I fitted to the BVision are so its almost not worth turning that one down!

I think I'd take your solution over mine if I had the guts to do it, I made sure all my mods are reversable - I always follow that rule.

I admire your Kahuna's my friend :thumbsup:
 
Yep, when I glued those nuts to the board I felt my a***h*** tighten up at the thought of whether I was about to flush 600 Euros of PPC goodness down the drain! Really big risk, but great fun! :D
 
Super nice project your working on. :)

Just a question. Are you willing to make a batch of your custom 3.9 rom and put it up for sale? Or just the info how you made them. I have a similar setup like yours.

Hi!

Its not allowed to sell the burned Roms on Amibay (well maybe if you sold them with an OS3.9CD and genuine 3.1 Roms) however there is a guide that mfilos done:

All the best,

Steve.
 
Hi Flowman, Its like Steve says mate, this stuff be da chitz and its still very much copyrighted materials. As long as you have a genuine set of OS3.1 roms in your Amiga, and you bought yourself OS3.9 original, then you are good to go on mfilos' awesome guide :) The programmer he uses is dirt cheap on ebay and so are the EPROMS, give it a shot, its great fun :)

Cheers! And welcome to Amibay :thumbsup:
 
Here's some more stuff!

PSU.... what a PITA! I've bought 2 mATX units, one cheapo, one expensive (was a seasonic 350W) none of these worked. I ended up pulling 3 full atx PSUs from old work pcs to do some tests and all but 1 failed on +5V. The one that passed and booted my machine reset when ever I put a CD in the drive! so the only PSU's that work are my old trusty ATX and the APOWER. Well I decided to stick with my old trusty ATX and give Ziggy my APOWER (as it was getting very hot).

I also decided to put the A1200 aside for a bit and get Ziggy's A600 up and running properly with VGA out and fully loaded HDD with WHDLoad and games.

I was sat happily loading up Zig's A600 and after about an hour I noticed something....... The APOWER was getting hot!!? almost as hot as with my A1200, "this isn't right" I thought. So I took it out of the plastic casing, and it was then running ALOT cooler. I did the same with my A1200 and again it ran alot cooler than before (a bit hotter than with Zigs A600, but not stupid hot) I don't know why I didn't think of that before! So I decided to give something a try, put the APOWER in the original PSU I got off Steve a bit ago instead of an mATX PSU. So here is how I did it: -

Here's The PSU in all its original glory.


07032011063.JPG


Inside the original supply.


07032011064.JPG


I need to cut these wires out.


07032011065.JPG



The supply sans board, I took a quick note of the voltages for each coloured wire. bear in mind that the colours can be different so if you plan to do this, double check the levels with a meter before you start wiring up.


21032011173.JPG


21032011174.JPG


I had to do some trimming :)


21032011178.JPG



I hot glued a 12V Fan in the top.


15042011278.JPG



Here's the APOWER out of its case.


15042011280.JPG



Wiring up to the Power lead and switch.


15042011282.JPG



Quick check it all fits ok.


15042011283.JPG


15042011284.JPG



The APOWER fits onto 2 of the original mounts with a small amount of grinding on the board.


15042011285.JPG



Mounted a block terminal for attaching the DC lines.


15042011286.JPG



With all the lines connected.


15042011288.JPG


Full view of the supply all in with the fan over the top.


19042011299.JPG



I made a small PWM fan controller to bring the fan noise down to whisper quiet.


15042011289.JPG



And there she is with all assembled.... who could guess it has a small beast in there?!

I actually did this mod about 3 weeks ago, and since then its been running both my A1200 and Ziggys A600 when i've been working on it. And its not getting hot at all, its ultra cool and ultra quiet now, even in these hot days we are having at the moment in Denmark!

On a note of heat, my A1200 seems to be handling the high early summer temps at the moment. Its getting generally 2 degrees or so hotter than before on the CPU's and BV but i'm still not running it any more than 2 hours at a time.

Ok, I bought some more things too: -

04052011352.JPG


A Lyra II 1200, I'm gonna try and force this into the old girl to allow external keyboard connection. So i'll be totally ripping off Marios' awesome mod, I hope you don't mind mate :)

04052011353.JPG



A close up of the beaut, the jumper at the top there allows PC or real Amiga keyboard connection, i'll put a switch under the back lip a bit like the manual video swich to choose between these and plonk some wires on that jumper header.


04052011354.JPG



And finally for now, I bought a 320GB PATA drive, yes its a bit OTT, but i'm a bit of a to the maxx kinda guy so figured why not!

I see that OS 4.1 Classic is finally imminent so will plump for that when its out and see how it runs clean on this drive and keep the 80Gig one loaded as it is for now as a backup.

Oh! I also redid my custom 3.9 roms and simply put the old SCSI device from the original OS 3.1 roms for now until Cosmos' betas are sorted. I didn't try PFS3 yet, but want to get started on the 320GB drive now on the 3.9 Partition. the 80GB drive will be my fallback (as its set up to easily change my ROMS should I need to) and build the 320GB up with all the cool chit.

What else? Oh yeah, I want to put my DVD drive through a regulator connected to the +12V line to try and take a small bit of fluctuation off the +5V rail.

Anyway, thanks for looking! :thumbsup:
 
Nice updates as always mate, glad the PSU is serving you well :thumbsup:
 
Cheers Steve! :) Yeah the PSU is awesome!

Well here's my latest stuff: -

11052011388.JPG


So there is the keyboard controller the Lyra II has to sit on.



11052011389.JPG


And i'm gonna take out the Video phono plug and place the PS2 plug there instead.


11052011390.JPG


Hmmm... this needs modding!


11052011391.JPG


EEK! Best not remove the connector then :D


11052011392.JPG


Didn't say anything about soldering wires underneath voiding warranties did it? ;)



11052011393.JPG


The level of destruction needed to take one Video phono connector off.



11052011394.JPG


There it is!


11052011395.JPG


Out you pop me lad!


11052011396.JPG


This is just an experimental 12V to 5V mod I made for the DVD drive. It didn't work so well, the drive wouldn't spin up a disk on a warm reset properly so I eneded up taking it out after the Lyra II mod.


11052011397.JPG


There is the Lyra II in place.



11052011398.JPG


But I realised I have to move the wires as they get in the way of the IDE Fix Express.


11052011399.JPG


bit of tape to insulate.


11052011401.JPG


On goes the Indi and IDE Fix.


11052011402.JPG


I Took the board out again to solder on the PS2 connector. same methods I used to hold on the Audio mixer, basically soldered the body of the connector to the metal sheilding.







11052011403.JPG


There we go, nice and flush. I had to heat and move the connector a few times to get it in the right place.


11052011404.JPG


Testing the fitting with an Amiga keyboard (well a CDTV keyboard with a CD32 Adapter).


11052011405.JPG


And with a PS2 PC keyboard, both plug in snugly.


11052011406.JPG


Sliding the board back in... ooo, it JUST fits!


11052011407.JPG


1 mm to spare underneath.


11052011408.JPG


Roughly drawing where the wires go on the PS2 connector.


11052011409.JPG


And soldered on.


11052011410.JPG


Here's the switch I have connected to the keyboard selector jumper. Shorted = PC keyboard, open = Amiga Keyboard.







11052011411.JPG


From underneath the lip.


11052011412.JPG


Another one of those wide shots of all the sh*t in my A1200, how it still works baffles me!


11052011413.JPG


The Lyra II just nesting quite tightly in there!


12052011415.JPG


Added some stickers to be sure, don't want to forget and plug the wrong type of KB in!


12052011416.JPG


Did the same for my manual override switch on my Auto Video Switcher. Not as dangerous, but still good to have :)


13052011418.JPG


The keyboard works! :)


13052011417.JPG


CDTV Keyboard with a CD32 (A4000) adapter :)

So thats the Lyra II in! And it helped very much already not having to keep the original keyboard in when needing to do tests (I was doing some tests with the clock port adapter lastnight, swapping ports)

I'm gonna plug in the 320GB HDD next, load up a vanilla OS, and get some partitions going on it :)

Thanks for looking!
 
I knew that you'd find handy the PS2 connector on the miggy my friend!!!
I for sure never regretted putting it :)
Awesome work as always and a definite fine documentation as well.

/salute with respect
 
Les for President :thumbsup:

You da man, awesome, awesome work as always :bowdown:
 
A job well done, and great pics along the way! Thanks for sharing! :thumbsup:
 
OK, so forgive me for asking, but what's the point in having a Lyra installed in a wedge Amiga?

As you can see the lid spends most of its time off the Amiga lol so he needs some kind of Keyboard attached for testing! :ninja:

Well for example, lastnight I did a tedious Clock port expander test for someone over on EAB. I had to plug the subway from one port to the next 12 times with multiple reboots between and checking software, then swap a wire and do it all again to get some results.

If I had to do all that with the original keyboard installed it would be annoying (And my older keyboards ribbon cable broke through lots of bending back and forth). I can now have the system running completely open without having the internal keyboard in the way. Even just for simple things like soft reset salute. Its now also going to make displaying the system running with the cover off alot easier for show purposes (I'm thinking of R3play, i'm quite sure most of you will want me to rip the lid off instantly).

Now I just need to figure out how to make a beer spill protector :D
 
Aye Steve, It will deffo go in hand luggage no doubt about it, the most scary thing for me is getting it through security without them thinking it has a bomb wired in there! :D
