I have an old working Mac 512k. It even has the original Apple team's names on the inside. The thing that's special is that it has a RAM upgrade. AMASING! This isn't your plug-n-play type. It actually has a circuit board on top of the main logic board and everything is soldered together. Looks like it would of took HOURS to do. Maybe if anyone is interested I'll open her up again and get some pics. Anyone else out there seen this? A.J.
