Since I have one laying on my desk...

Barely the length of a short ISA slot, with fingers on the end like a
floppy drive edge connector, as well as a set of header pins for a floppy
drive cable that goes to the "real" drive. The card is in series with the
floppy drive cable.

It has one main chip, about 8051 sized, maybe 60 pins:

Transcopy 3 c CPS
TC19GO32AP-0036
Japan 8819EA! the ! could be just a vertical line.

There is a 48 mhz crystal, and a 1987 copyright. Two sets of jumpers seem
to select between PC/XT and AT/Compaq, another set looks like DMA1 or DMA2.

Remaining chips are a LS245 to the ISA bus, a 7406 by the PC/XT jumpers,
and a 8812S UM8326B next to the crystal.

*********

My guess is that knowing what the big chip is and does is the only "catch",
the rest could be traced out in a few minutes.
