I don't know about _that_ card, but I have a full length card with an
8X305 chip on it, plus a 50-pin connector to, IIRC, a common-enough
system interface for pre-DOS machines, and connectors for two hard disks.

It came out of a Davong shoebox and is the (distantly related) ancestor
to things like the Adaptec and OMTI SCSI<->ST-506 boards, but for
8080 and Z-80 machines. It was sold to me at the Hamvention as a SCSI
shoebox. The seller was wrong.
