I started collecting 8/16 bit computers sometime in 2000 and later branched into consoles as well.
I have all sorts of vintage computers in my collected but the bulk of it is Commodore: VIC20 (3), C64 (4, but only 2 working), C128D, C16, Amiga 500 (4), A600, A1000, A1200 (3), A2000, A4000, CDTV, CD32 (2). The rest of my collection is a mishmash, quite a few computers but no effort to "complete" any particular line. Got some Apple ][s and Macs, Sinclairs, BBCs, etc.
On the top of my wanted list is a working Sinclair QL -- so should you have one you'd like to sell/swap do let me know!
