For Sale - Pair of IRMA2 IRMAlink cards for IBM Microchannel PCs

These are two complete sets of networking cards for the IBM Microchannel architecture PCs.
Manufactured by DCA - Digital Communications Associates, Inc.
IRMAlink IRMA 2 3270 Micro-to-Mainframe communications
IRMA 2 supplies the personal computer with direct coaxial connection to an IBM 3174, 3274, 3276 or Integral Terminal Controller with Type A adapters.

These are from the late 1980s, and are extremely obsolete. They may be of interest to a collector of old PC systems.
I'll only sell them as a pair. Price: free to a good home. Plus postage. Or pick up is OK.
These sets are ex-rental, and were probably working when disposed of as obsolete.
As seen in the photos, they are all very clean. The cards look as-new. The manuals have a few minor sticker residues.
I've never used these; don't have a microchannel PC. They came with some other stuff years ago and are so nice looking I can't bear to throw them out. Please, get them out of here.

Each set includes:

  1. IRMA2 card. The network connection is a BNC coaxial connector. Cards are in anti-static bags.
  2. Documentation:
  3. Software, on set of three 3.5" diskettes: One diskette set is labelled version 1.04A, the other set has no version marked.
