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.

Re: General Stuff(tm)
I've gone back to basics with my own test ROM.
I've managed to get it to read and write to serial port A now, which makes debugging a whole lot easier with output!!!
Anyway, enough for today.
