It makes being able to work on the motherboard for testing a doddle.
Can all registered uses please login, even just for a few minutes..

Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

Excellent, it’s always a pain to troubleshoot without this. Why are the yellow ICs (not the tantalum capacitors)?
Retro stuff
520 STF/ 1040 STE / Mega ST / 2 Mega STE / 2 H5
2 x 600XL with U1MB /SOFIA 2/ AVG CART / and a few 1050
Apple //c, Commodore 128, Mac Classic, SE/30, LC, IIvi and PB G3 (Clamshell)
Amiga 600 and a few 486 and 386.
Many Nintendo G&W and other electronic games from the late 70s/early 80s.

I think, based on other Mac logic boards like this, that they are resistor packs, though I'd happily be wrong.olivier.jan wrote: Mon Apr 24, 2023 10:09 pm Excellent, it’s always a pain to troubleshoot without this. Why are the yellow ICs (not the tantalum capacitors)?

Yeah, I believe that they're resistor networks.

Another thing I have done on the se30 boards when the tab breaks on the ram sockets I replace them with the single simm sockets used on the atari st in pairs
