controller chip, just a bunch of TTL logic.  I'm guessing either a
 proprietary bus or SCSI managed in software (a la Apple 2 Sider). 
 I;'ve never seen this machine, and know nothing about it, but another

 read/write/select signals, etc)

I have a scrapped Keypro 10 in the garage that I can pull a WD1001 out of
if worse comes to worse.
