Diamond Trackstar E

[Karl Asha <karl@blackdown.com>]

I just picked up a Diamond Trackstar E at an auction, which for all 
intents and purposes is a IIe and z80 on a pc card. It comes connectors
for apple drives, joysticks, monitors, etc, and some ms-dos drivers. 

The last known location that was distributing these things seems
to have been Tandy. What I'm trying to find is some sort of technical 
information for the card so as to allow me to write a linux driver for
it. 

Anyone ever run across one of these and know more about the inner workings
of them?

Cheers, 
Karl
