    I've heard of those drives but I don't think
this is for a drive.  The
 only connector on it is a three pin plug that is accessable through a hole
 in the metal bracket.  There is one 20 pin DIP socket that might be used
 for a connector but it looks like it's for an IC. 
This is an Omninet interface.  1Mbit/s RS-422 twisted-pair bus
networking.

The interfaces for the Apple ][ (a card) and Corvus Concept (built-in)
have 6801s to actually do the work of moving packets between the
computer and the Omninet.  I'm not sure if that's what is missing from
your 20 pin DIP socket or if it was intended to hold a BIOS extension
ROM to let the PC boot over Omninet.
