Hey, I've got a DCA controller here in front of
me. It's a full-length
8-bit ISA/MCA flippy card, with 1 BNC & 1 RJ-11 (4P4C) ports on it. One
sticker says `*LA 0006E1*' and one says `003581 REV.A' A little googling
indicates this might be some sort of 3270 controller, but I couldn't find
anything to confirm this. Anyone know what it is/want it?
I haven't seen the thing in years, but Wollongong had something like
this in the QA lab. Made by DCA, ISA on one edge, MCA on the
opposite, with a daughterboard that plugs into one side or the other
depending on which bus you want it to ride. Oh, and it had two
different back plates (one for MCA, one for ISA); you attached the
appropriate one to the daughterboard. I don't remember what
connectors it had poking out the back.
Anyway, it was an Ethernet interface. I wouldn't be surprised to find
out that they made IRMA 3270 interfaces this way too.
What does surprise me is that Attachmate (who bought DCA) appears to
still sell something like this: the "IRMA 3 Convertible Adapter".
