A weird DEC cable, DB25 male on one end, and what
I think is QBus
female on the other (3 rows of pins, 17/16/17 - DB50?). I'm guessing
this will be a huge score to someone, just not sure what it goes
with. :)
I'm not sure how fair it is to call a DD50 "Qbus", since Qbus is a
card-edge connector bus.
The Qbus sockets on the back of my Vax 4000-100A are DD50 so I guess
DD50 connectors are used on Qbus cables for at least some applications?
But this might be a SCSI cable; I've seen both
DB25 and DD50 used for
SCSI (D-shell SCSI in my experience always uses male connectors on the
cables, but my experience with DD50 SCSI is pretty much limited to
Suns). It might be useful to buzz it out....
It sounds to me like a V.24 adapter cable for something like a DEMSA X.25
router and various other DEC synchronous serial items. This would seem to
be a BC19D-02 from what I can find. Is there a part number stamped on it?
