If you are going to replace original phase5 heatsink to this one, please pay attention not to crack 603e silicone core.
It's quite fragile - I was forced to replace few mechanically cracked 603e.
 
If they followed the cad-file it shouldn't be a problem. Done one myself and it works very good on a BPPC that was boosted by you :)
 
They certainly did follow the CAD file - the original cooler was removed by the previous owner many moons ago, as they'd stuck a fan/heatsink combo to it that Chucky managed to remove for me when it went for a rev. 6 upgrade. He did a nice job of cleaning the 603e too - the cooler is currently attached with the clips and a bit of Arctic Silver; it hasn't gone solid so no problem there. Still waiting on the finished heatsink, but Lithium enriched Copper does a really good job of moving heat!
 
Sooo... I bought 3.1.4 whilst waiting for my keycaps, and for the heatsink, which seems to be taking forever. I'm working on new custom ROMs at the moment, so once I've something working well, I'll post the new content :)
 
I've finished off a new 3.1.4 ROM set, which are working lovely - I've a good chap burning those for me in the next coming days :) Be aware that when splitting the ROMs, you need the newest version of ROMsplit and Remus from Doobrey. Content is as follows:

Then in the Extended ROM:

Checking this content made me realise that the Poseidon changes were missing! :)

New ROMs in:

New OS is done too - runs lovely now, and a number of small issues seem to have gone away to boot.

Something else I'd been meaning to get around to was trying the 50Hz config for the Indivision AGA - although this little monitor doesn't like it much (my main one does), you can see how smoothly it runs!



Edit: lol! YouTube has added a stutter to the video...

Finally got handed this today:

I'm now moving house though, so will have to play with it when I'm done :-D
 
This is somewhat a more meaningful post than what I've been posting for a while; I've replaced the old lower RF shield with a VGA cut one from CenturionTech, as I'd removed so much of the original shield that the mouse port bent inwards when inserting a device, and the VGA connector was sloppy as I'd moved it more than once (to accomodate a Ratte Switch). These are both solid feeling now as the plate is much thicker:

When refitting into the case, it's necessary to put a washer (I used a rubber fitting to help silence the FDD) to make up the gap when refitting the FDD:

Here's the old versus new heatsinks; the newer one is a little taller than the original (and much heavier!)

6-B9-CBB3-C-8061-47-E2-BB94-549-ED48-D9-DEE.jpg


Attached to the card it is a much better (tighter) fit than the original

And the trapdoor needed to be altered to allow it to sit nicely in the case

33-B0-C885-BF5-A-4-CFD-B911-E67-D97154-F63.jpg


Which when cutout, made for a great fit:

And was it worth it? Totally; the ambient temperature inside the case has dropped to 32C from 45C so it's aiding the removal of heat at a much better rate than the original. Even after several hours of operation the case temperature is still stable at that too; despite having a BPPC in there. Thanks to all involved! :thumbsup2:

Very nice custom cooler! I have almost exactly the same setup as you. Running without bvision at the moment, but with scsi (aztecmonster adapter). I've tried twice to make a custom rom with bppcfix, but only getting a black screen in the real machine. Roms works in FS-UAE though, and untouched 3.1.4 roms work. I'll try your ROM build now. Thanks for posting it!
 
At Geekfest 3, I discovered that my Iiyama 17" LCD wasn't as capable as I thought it should be (can't find the reference to it) - so I bit the bullet and bought a Benq 702A which not only supports all of the 15kHz modes, but also older VGA modes such as 640x512@50Hz which means that my Indivision should be perfect with this screen. I've ordered an RGB to VGA adapter also, which will be really handy for other meetups, as we'll be able to use the screen with other Amiga's.

Still waiting on news/return of my RapidRoad, but in the quest to fit more things internally in my Amiga, I've started developing a PCMCIA extension. I've all the bits on order, and hopefully it won't be too ridiculous for my friend to solder together. Assuming it works, I'll release the parts list and gerbers for the boards as open source. RastPort is also working on something similar, but with IDC cabling (very fine pitch) - hopefully something will come of the combined efforts!
 
Got my RapidRoad back - looks like the FPGA was replaced along with some of the passives; hopefully they're hardier than the originals lol

The Benq 702A is a brill monitor, but it's just not possible to get a full screen picture through the Indivision at 50Hz (that I've found) - still, it's pretty good regardless :)

I made a bit of a cock-up with the PCB's for my PCMCIA adapter, as I foolishly followed the data sheets for the components; which assume that you're using the parts as intended rather than how I wanted to use them lol - lesson learned and new PCB's are on the way!
 
Added the Clockport Expander II that I obtained to my Amiga this evening - all ready for another clockport device when I can find/afford one :)

The tower can be fitted rightmost into either ROM socket, with the cables to towards the rear of the case...

CCCBA5F1-85B6-43A8-9721-23A2292BFD7C.jpg


I opted to unattach the cable, and run it through the hole for the HDD cradle to the rear of the board and solder it directly to the rear of the lower ROM socket.

And there we are - a little bit more cramped than before lol

Still working on the PCMCIA extension... Keep making (silly) mistakes!
 
Fits well! Although somehow I've broken something at the moment as the machine refuses to work... Even stripped down to just the mainboard lol

Think it'll be off for repair!
Hehe, looks good!
 
Reflowed the pins that I'd soldered to for the clockport expander, and it's up and running again :D did the IDE pins whilst I was there to make it a little more reliable.

Made some progress on the PCMCIA extension - I finally have something that is mechanically correct, but when measuring for continuity, some of the pins have more resistance on them than I'd like; so as a consequence it doesn't work (with a 30cm flat flex cable).

I've ordered sizes between 25cm and 10cm to see if a shorter length would allow it to do the trick - I'll start with the shortest and see what I can get away with should it work. Seems to take 2-3 weeks for them to arrive from China, so I'm about a week or so in, so far!
 
Got the shorter flexes for the PCMCIA extension, but even with the shortest one which from a resistance perspective is perfect, I can't get a card to work on it. Must need the signal buffering or something which is beyond me!

I had noticed that the keyboard rested against the clockport expander II that I fitted too, which isn't ideal, so I opted to remove the 68EC020 as I don't (and won't) use it.

After:

And now the expander fits lovely:

As I don't own a hot air rework station, I used Chip Quik to remove the IC (after practicing on some DVD player boards) - it makes the job really quite easy!
