So, I recieved the "Unisys Personal Workstation MPI 4253" machine today, opened it in order to get a closer look at that unidentified ISA card that are in Slot2. And I have absolutely no idea on to what it is at this moment. The connectors are two 15-Pin. One male, one female.

The card are produced in Denmark, and is from Dataco A/S... Hmmm... Danish hardware. Most likely an I/O-Card of some sort. Do any here know what this card is? I have taken three pictures of this card, and attached them.

I tend to think this is some kind of token ring adapter. This company - Dataco A/S seem to be specialized making them.

A NIC:

Edit: With some own intelligence:

Thus it's more than a simple NE2000-alike.

Thanks....
Must be a token ring of some sort. Hmmm... Why the male and female connectors then?
Just strange that the seller had a 3-Com NIC card in this too.

Token Ring cards have female DB-9 ports on them, not DB-15.

Why does it have a DES decryption option? Why two irq selection jumper banks?

More pictures please...

Dataco ScaNet adapter?

Looks like it. ScaNet also offered a DES encryption option according to https://goo.gl/apXeLI

The connectors were proprietary and could support several external modules for various networks. Neat card.

Or maybe those are twinax interfaces?

Yeah.... That encryption option baffles me too. I have been discussing this on G+ as well. Seems like it is just an old NIC that can be used in some sort of secure enviroment.

That's all I can figure out.
