Ah, to the swiftest go the spoils. I was after that too. When did you pick that up? I told him I'd take it and he said ok, be there at 8:30. I got there and he said it was sold/gone, along with the Marble Madness. He could have told me that before I made the trip.
I did pick up the Red Baron aux board, Blaster I/O board and the 5 68000 CPU's (used in Quantum among others). At least you left those for me!
So, if you need it, I can test the Atari System 1 stuff for you very easily at my place (one of the few games accessible right now).
Did you buy anything else?
