Very rare! This is a switchable RS232 interface adapter expansion card (with modem cable), for NCR Decision Mate 5 (DM-5/DM-V) computers. KIT 3273-K801-V001. This unit comes equipped with a 96-pin connector that plugs into the back of the DM-5 computer, along with a 25-pin connector at the end of the modem cable. The unit also features DIP switch that allows the user to switch between Printer, Plotter, and Communication applications. On the end that faces out from the DM-5, there is a 20-pin connection that is labeled "Modem". This unit is in excellent condition for its age (being made in the mid 1980s), and has only a few small paint chips here and there. This would make a great addition to anyone's collection or museum. My late father worked for NCR for over 40 years, and was part of the original DM-5 development team. This unit will be responsibly packed in a sturdy box, protected from moisture, and will arrive exactly as shown in the above photos.

On an ending note, I am still going through a bunch of my late father's collection of vintage NCR computer stuff. If there is anything in particular that you are trying to find, please let me know and I will be happy to check on it for you.
Also feel free to check out my other listings, as I am constantly adding more vintage computer items (in addition to what I already sell), as I continue to go through my dad's collection.
