I'll collect almost anything old, video game related, or electronic.
Favorite systems: Atari 8-bit computers, Atari 2600, Intellivision, Colecovision, Nintendo Virtual Boy, Nintendo NES, Vectrex, GBA, Commodore (anything Commodore but especially VIC-20), TI 99/4A, Atari 7800, Atari Lynx, Sega GameGear.
I also LOVE old handheld games. Mattel Football, Basketball, etc.
There was a prototype leaked a couple years ago for "Pete Best Western", a hotel management simulator on the Magnavox Odyssey 2. It even used The Voice to make snarky remarks about being kicked out of the band before they got big.
