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)."

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)
