That's a Z80 card. Assuming you have the disks that go with it, it allows
you to run the CP/M operating system. (Back in the days when there were still
hundreds of different kinds of computers, instead of just Mac and IBM, CP/M
was a very popular operating system...it could be made to run on just about
any computer with a Z80 CPU, which included a significant fraction of the
brands available at the time.)
Somebody else suggested that it might be a clone of the PCPI AppliCard.
Given that it has those four switches, and no connectors, though, I doubt
that it's a PCPI clone...more likely a Microsoft Softcard clone. They way
to tell for sure is to look for memory chips...if the card has memory on
it, it could be a PCPI clone. If it only has the Z80 and a bunch of
74LSxxx logic chips, then it's probably a Microsoft clone.
Whichever kind of card it is, it'll be of no use to you unless you have the
software that goes with it, i.e. a CP/M boot disk.
