I really couldn't see this happening, using DEC's box anyway.  The thing
in the TK50Z-FA/GA is a SCSI target and a TK50 master.  I don't know anything
about the TK50 bus (although I wish I did -- anyone have a pointer to docs?)
but I'd be very surprised if it can be easily turned around backwards (i.e.
if there are unidirectional lines then they're going the wrong way, etc.).

SCSI is a bidirectional bus so chances are the same hardware *could* be
programmed to run as a target (I forget what's in there, something generic
like a 5380?  or did they tool it out in loose logic?), but you'd need new
firmware for the adapter board, and I doubt you'd be able to dig up DEC's
internal documentation (if it ever existed in writing) on the programming
architecture for that board (port definitions etc.).
