@mos_8502 Yeah! I actually have to keep a spreadsheet for mine now :-/ But the ones I actually use from time to time are:
* Atari 800XL, U1MB, dual POKEY, FN, Ultimate cart
* C64c (PAL)
* Amiga 1200, ACA 1221LC
* Color Computer 3
* Color computer 2
* TI 99/4A
* Fujitsu Pentium-100 laptop
* Gateway GP6-400 Tower (P2-400)
* ZX Spectrum +2 Grey
* ZX Spectrum (48k, Issue 2 I think)
* CPC-464, 512k upgrade
* BBC B, 32k Sideways, TurboMMC

And last, but certainly not least: My childhood Atari 400 with 48k upgrade and composite mod ♥♥
