It should have the same motherboard as most of the other '84 series of
machines. Primarily characterized by the presence of a 50-pin header -
or at least the traces for it - that was used to interface to the
WD1002-HDO bridge HDC via a translation card that took the 50-pin
connection down to the 40-pins used on the WD unit.

It should also have a RTC and a 300 baud modem installed or, at least,
the traces for them. The boot EPROM is likely either numbered 81-292
or 81-478 on a paper label. Knowing that information, and if you have
access to TeleDisk, I can email you a disk image for it.
