F/S - 3.1L G1 Memory Adapter with C1 Atmel AT29C256 Chip
 

Got this off a friend of mine. He installed it on his 91 RS V6 3.1 Camaro and ended up junking the car, so thats why its in my hand now. Im not too sure what was done with it, he got it from www.moates.net . Its a $36.00 value, so im willing to let it go for 20 smackers.
