You make me chuckle. The topic of SCSI "standards" is far
worse than the problem you are having.

Then to complicate things... given some devices.... you
might have the cables to connect things but oops, you are
connecting to a RAID array which uses high voltage
differential SCSI. Need different card in the host. Then
there's the whole Fiber SCSI / Channel thing...

In a perfect world your PCMCIA adapter would have the cable
terminating in a HD50M that it probably came with
originally. (well, as Adaptec PCMCIA cards originally come
with:  both LD50 and HD50 cables)

SCSI Host Bus Adapters, drives and peripherals *usually*
have a female connector on them, IMO. So in my view the
PCMCIA adapter (with its proprietary connector on the card)
and your female-femail adapter is oddball.

Hey, if everything connects and the cables are not too long,
BE HAPPY.
