So I'm at the flea market today with Mike (klimatron) helping him decide if he wants a C64 or a Sega CD when the vendor asks if I saw this (points to an Atari Video Music). Wow! No I hadn't. Now, I wouldn't be posting this here if that were the end to the story. When I expressed interest he says "I think I have another here" and sure enough he did! Even better, I take them home and they both work! So I now have an extra AVM for trade.
