If a schematic isn't available, but a unit was made available on loan
to reverse-engineer, I'd be willing to do it. Recently I
reverse-engineered a schematic and the firmware of a Zendex ZX-200A
Multibus floppy disk controller, which replaces both the iSBC-201
single density controller and iSBC-202 double density controller used
in Intel MDS systems:
