Rich, I have some docs for it - about 10 pages - that I will mail
you given an address. But in the interim, here is some
information that may be useful:

        J1 Bus extension
        J2 Winchester Interface connection to an IMI 7710
                Winchester controller or equivalent
        J3 Serial port
        J4 Serial port
        J5 Parallel printer port
        J6 8" floppy drive
        J7 5.25" floppy drive
        J8 Power connector 1,2 NC, 3 Gnd, 4 5VDC _at_ 1.5A

        DIP switch - 8 position is used to initialize the FDC
                SW1-5 SW1-6 SW1-7 SW1-8
        SDMini off off off off
        DDMini off on off on
        SD8" off on on off
        DD8" on on on on

That ought to get you started, anyway.

The boot program is 32 bytes in a ROM. Tiny!
