Howdy, long time no post. I have a Atari 2800 Galaxian box (that's the Japanese version for the uninitiated), never assembled, for sale on eBay at the moment that's not really getting any love. If you're interested it's http://cgi.ebay.com/ATARI-2800-GALAX...#ht_685wt_1166
I've also got a loose (untested in the last 10 yrs) Jaguar CD unit up there, but knowing those things it's probably not working so I wouldn't bother...
