I don't know what the model is called, but the
genuine IBM card has
FRU#93F0377. I see them all the time. The SAS interface is a single
MCA card. The DAS interface is an MCA card with a MCA daughtercard
which takes (I believe) only power from the slot and communicates to the
main board via a ribbon cable. MIC connectors all around.
The ones we used were different. They were single MCA cards with
daughterboards, and the FDDI connections were STs. There was a kludgey
cable just sticking out the back for the connection to the FDDI bypass
switch. The HSSI cards were very similar, but the daughterboard was
different, and obviously no STs or bypass controls.
The very early 386 based ones were really odd, in that they were about
three times as tall as the MCA standard called for. Why they did it this
way - who knows? The RS-6000 mod 930s we had were in extra tall chassis to
support the card.
I believe I have a MCA V.35 card or two. The ones I
have are ARTIC960
i960-based coprocessed serial interfaces that speak V.35.
Those I have seen, but not too common.
Hmmm...very interesting that the FDDI cards were apparently upgraded and
released - I was told they were a dead end.
