Vintage DCA IRMA Nubus Card and Sealed Workstation Software for Macintosh

Description

You are bidding on a DCA IRMA IBM 3270 video terminal emulator Nubus card & software for vintage Macintosh computers.
It's vintage Macintosh Nubus card week!
See my other listings for many and varied vintage Nubus cards for Macintosh computers.
DCA IRMA was (is) a hardware/software solution that lets a Macintosh computer (or a PC) look like an IBM 3270 video terminal so that it can talk to iconic 1960's and '70s IBM mainframes such the 360 and 370 systems.  Not too many of those Big Iron computers around anymore, so this item will mostly be of historical interest to collectors.
This listing is for a used DCA
IRMA card that fits Macintosh II-series computers that can accept a full-length NUBUS card.   The listing also includes a sealed copy of the required terminal emulation software.
The card is used, but I cannot test it because I do not have access to a suitable IBM mainframe.
The
sealed software package is for the Macintosh computers listed in the last photo, but you'll have to do some research to find out what the system memory and OS requirements are.
I have been collecting and restoring vintage computers for a long time.  Please see my other auctions for more vintage Macs and Mac parts, plus occasional other vintage computing items.
