As for grail items, I've got three:
- Osborne 4 (Vixen) -- A friend of mine had one after passing me his Osborne One. It may have been peak CP/M.
- Commodore PET -- They look just so darn cool!
- Quadra 840AV -- The best Quadra, and I used one at work back in the day.
- IBM 5150 -- Changed the world--not in the same way as the Mac--but nevertheless.
- IBM 5170 -- The quintessential PC.
- Amiga 500 -- I never had an Amiga, never used one, but I'd like to fiddle with it.
