Jet-Disc Disc Drive System

per drive. The unit includes the disc controller, one drive,
power supply, interface cable, and software. The box will
accept another drive, and the controller can be configured to
control up to four 3", 5", or 8" drives in any combination.
Also provides up to 4k of extra EPROM and/or RAM.

Jet-Disc Schematic

We do not know what code is in the eprom that controls the Jet-Disc, also we expected a disk controller chip and not the 6821 and 6850 chips. You can download a Hi-Res png image and Data sheets for the 6821 and 6850 chips in this zip file [10 meg]. If anyone has any images or a ROM dump of the eprom or even any discs it used, then please consider lending them so we can preserve them.
