Wow, it sounds like somebody just lost their GRiD-virginity. John H. took
my 1535EXP, so I have to go from memory. It's a 386DX-33 (in a PGA, so
you can upgrade it via Cyrix/TI/etc) with up to 8MB RAM (low-profile
SIPs). I think it wants 16-18V DC, center neg. The empty hole will
accomidate eithe battery or a power supply with an AC plug.

The GPIB was probably intended for compatibility with earlier GRiD
peripherals, and will be automatically detected by IntegGRiD, a version of
GRiD-OS that runs on top of MS-DOS.

The connector on the bottom of the machine plugs into a docking tray,
which John H. also took and I think was trying to sell last time I
checked. (John, are you there?)
