Microsci HAVAC

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
