I'm pretty sure I have it. IIRC, though, it's just buffers and maybe
address decoder circuits, so it should be trivial to reverse-engineer the
card, if you need to know what signals appear on what solder pads, etc

The TechRef is nothing more than the physical dimensions of the card and
the schematic of the IBM-built part. There are no examples of how to use
it, or anything like that.
