an interesting round-up

Ok, here's some of what I arrested into the custody of my collection yesterday. A zero-emission Mac 512K. This is truly bizarre. Its a normal looking Mac 512K until you look closer and notice there is a second built-in floppy on the right-hand side, oriented vertically. The brightness knob is missing from the front and replaced with a little square that is the same color and texture as the rest of the case. It was moved to the back. The power cord is not detachable like on a normal Mac but is instead permanently attached. The external disk drive connector is gone, and so is the slot where you can insert a security cable; its covered over. Opening this thing is half-past a bitch and a quarter till a pain in the ass. I finally get it open by removing all the screws on the DB-9 connectors on the back and find a totally shielded interior. The disk drives and motherboard are encased in aluminum. The monitor has a gold foil pasted to its entire exterior. The video cable is shielded inside a heavy duty stranded shielding, as well as the cable going to the second disk drive. Even the DB-9 connectors have extra shielding around them. It was made by a company called Systematics General in Sterling, Virginia. Anyone know anything about these?
