I reckon the self adhesive should be fine, its come a long way in the last 10 years.

Btw, i tried poolmem and it doesnt seem to make any difference using the NOCHIP option, I havent really tried any other options yet tho.

Not a big deal tho as I have a rev8a board and 1mb trapdoor ram board on the way and will soon have 2mb chip ram + 8mb autoconfig fast ram.

Glad I could help you spend some money ;-) 2MB Chip RAM is the way to go, WHDLoad works great on an A500+

Well folks I got all the various bits I needed to try making my 500+ work with sata/e-sata but unfortunately even after trying every trick in the book I couldn't even get my Miggy to boot from my CF card let alone work with the external DVD-ROM!

I strongly suspect the limitations are caused the IDE68K adapter which doesnt seem to like having anything other than a "master" device connected. I couldnt even get my CF-IDE and DVD rom to play nice using stock IDE connections.

Oh well, for now Im just going to run with my 25watt Amiga power brick and a basic config and not worry about having a higher powered PSU and External DVD drive.

I'll prolly get a Zeus68k accelerator when they come out and revisit my experiments then but for now my 500+ does make a great little WHDload Machine as is (been playing the Space Quest Series again and loving it!).

I bet if you installed OS 3.9 it would work! Save those things for a proper computer. The A2000

It's an IDE68k HW limitation, not software - everything lights up and is active but KS3.1 cant recognise the CF Drive on the sata bus. If the IDE68k was a buffered IDE device it would most probably work fine.

I'd have a 4000 if I could afford one!

Got my RamSinks today and promptly installed them in varying quantities on all the major chips although I did have to remove the one closest to the camera from the 68010 as it prevented my keyboard from sitting all the way down:

http://dl.dropbox.com/u/71121999/Ami...2018.43.52.jpg

and to see if they fix my overheating problem (was only lasting for about an hour before crashing) I have SWIV on Floppy currently looping it's intro screens and music.

WoooHooo, overheating problem sorted! After an 1/2 an hour of looping the SWIV intro then extracting a highly compressed zip (a Demo) and then running the demo via WHDLoad for about 40mins (Fairlight & Virtual Dreams) my Miggy is still 100% stable.

I checked the RamSinks and most of them are very very warm so they are clearly doing their job of extracting heat from the chips.

What did you use to stick the sinks on the ram chips?
I use "Arctic Silver Thermal Adhesive" to fix heatsinks, it's permanent but it does the job a lot better then sticky heat pads that some use
Just a tip, good tho that you sorted it out

I've read that the thermal tape does quite a good job really. Although I haven't tried it myself yet. Positive point about the thermal tape is that it can be removed like you say. I'd be too much of a wimp to use the permenant solution.

The RamSinks I bought have very thin adhesive thermal pads on them and are more than good enuf - 2mins after switching off my 500+ the formerly hot RamSinks where cool to the touch. Interestingly my case around the CPU/Denise area used to get warm to the touch, now the RamSinks are doing such a good job of transferring the heat into the air that my case no longer feels warm at all.

Considering the Miggy's chips where designed for use without heatsinks, I dont believe there is any need for a higher quality thermal adhesive.

I'd been having some major speed issues with my IDE68k which I've now resolved and I suspect that I may be able to get my 500+ use sata now, so stay tuned, it may work after all!

I ordered some clear 3mm thick acrylic the other day and a cutting tool to make a nice little stand for my GBS-8220 ScanDoubler/Scaler. I think it turned out quite well as it's very stable and the VGA cable doesn't cause it to tip backwards any more - but I may make some improvements (use some different stand-offs and maybe makes sides and a top for it):
