Just had a look at the images on the Binary Dinosaurs site, and I see
that you have a blue, full-length card with an 8X305 on it. This is
a bit-slice CPU chip, so I'm curious as to what this card is. Does
anyone recognise it?
It's an IRMA Decision Support Interface, and according to an IT Glossary
I've found at mtsac.edu it's "IRMA - A circuit card and software combination
package from DCA which serves as a microprocessor responding to poll in an
interactive 327x network. It emulates a terminal while residing in a PC.
This makes PC's dual function devices - they serve as both terminals and
micros (see also AVATAR card)."
Pix are here:

Here's a post I found in comp.sys.ibm.pc.hardware.networking:
"This is not a 10B2 card...it is an IRMA board I believe. IRMA boards are
3278
clones made by DCA (as stated on the card). An IBM3278 board is a NIC for
a
PC to interface with a 3270 network. They're useless unless of course you're
running a 3270 network as well"
So that's me stuffed since I don't have a handy mainframe floating around
anywhere :o)
cheers
