    Another possibility is it attached to a 50-pin SCSI header on 
a Macintosh motherboard, with the dual DB-25 ports going to 
the backports.

    The original Pegasus cable was a one piece Y-cable. It
had the 26-pin connector for the RamFAST card, and that
split off into a standard 50-pin SCSI (to hardisk) and DB-25
(to back port). When my original cable was damaged a fellow
csa2'er (William Donnelly) attempted to repair it, but gave up
and instead mailed me back these two cables years ago as
an alternative. It worked well, until now....

Here's a picture of the actual damaged cable I need:

    Unfortunately that won't work. It needs to have the
dual DB-25 connector and be thin enough to squeeze
inside the Pegasus enclosure and not block slot cards
leading to the back panel of the IIgs case.

     Incidentally, I think I *may* be able to recover the data
on my SCSI drive if I swap the analog circuit board screwed 
on below with one from another Quantum Lightning HD.
Just have to find one.
