I am currently seeking to connect a Macintosh-compatible SCSI
port (DB-25, identical to the one on the Mac Plus) to a Seagate
ST-157N hard disk drive (which has a 50-pin IDS-style connector (two
rows of 25 pins). 

The problem I have encountered is in finding the right connector.
Consumer-oriented Mac SCSI drives have a 50-pin female Centronics
connector on the outside of their case.  Macintosh SCSI cables are
designed for the consumer-oriented drives, and end in a 50-pin male
Centronics connector.  This does not fit the Seagate's SCSI
connector.

What I am looking for is either a dead Mac SCSI drive from which I
can cannibalize cabling, or a 50-pin female Centronics connector, or
a source from which I can obtain one.  Failing that, any useful
information or advice would be appreciated.

It is impossible to find 50-pin centronics connectors in Pittsburgh.
Most of the electronics distributors around here are lucky to know
what computers even are, let alone carry connectors for them.  Radio
Shack doesn't carry 50-pin anything.

I find it hard to believe that given the popularity of Mac SCSI, that
there aren't more do-it-yourselfers out there that need exactly the
cable arrangement I am looking for.
