Well I didn't go to socketing everything @stephen_usher. Too much time to do and a bit redundant really.

So here is the board - recapped, issue 2 fixes, RAM modules.

ULA and UHF module removed and replaced with vLA82+ and internal video socket.

Yes it is upgraded :)

The vLA82+ screen output is so clean.

So, you basically replaced all the video circuitry so that you no-longer need the +12V rail at all, as well as not needing the -5V. :-)
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.
