Some of the more unusual antique/obsolete computers in my collection:

• Sol-20 Terminal Computer: A late-70s 8080-based machine, with integrated keyboard, video output, and S-100 expansion bus.
• Magnavox Odyssey II – Never booted up.
• IBM PCjr – Never booted up.
• Apple Macintosh XL / Apple Lisa – Not sure which one it is. Never booted.
• CEMCorp ICON + Lexicon – These were a government-funded boondoggle used on Ontario high-schools in the late 80s, early 90s. Most have been destroyed since then. It has been booted, but I wasn’t able to log in.
• BBC Micro – A friend shipped me one of these from England. I’ve never tried booting it.
