MIDIjoy: brand new. Never used and barely removed from box. Used as a MIDI interface for Atari and Commodore home computers. I got really excited about this one but never actually got around to using it. It's the version from Kitsch-Bent- see more here.
Asking $65, US shipping for $10.
Atomic purple Gameboy Color: works, but missing battery cover.
Asking $25, US shipping $10.
Can probably ship both as one. Make an offer. Not really looking for trades, but, try me! Would be interested in DMG/LSDJ-related.
