This weekend I picked up this wacky little 6502 computer called the Microsci HAVAC. Has anyone else ever seen one of these, or better yet, does anyone have a boot disk for it? The HAVAC has the weirdest floppy drive I've ever seen. It has a center-mounted clamp lever, and the head positioning is done via a spiral-grooved disc! The machine is about 16" deep, 10" wide, 8" tall, with the floppy drive in the center front (there is no door on the drive, just a slot and the funny lever -- no eject mechanism either, just pull the disc out manually). There is a small external keyboard about 10" by 13", no numeric pad, connects via a D-sub connector. On the back of the system unit, there are serial, "printer" (parallel?), 2nd floppy, and RCA video output connectors. I fired it up, and it displayed a HAVAC logo, ROM version 1.3, then the expected "no disk" error. I examined the system board, which is dated 1983, and has a 6502 CPU. There is no info anywhere on the net about this machine, that I can find. Any info appreciated, thanks Kai
