No idea what it's for but I did a Google search and got a lot of hits
about a Music-On-Hold modules perhaps it's part of an automated telephone
system. It has holes on the RH edge. They might for a bolt on slot cover.
You could dump the ROM and see what what you can find in the listings.

I found a rather old looking card. It appears to be an
8 bit ISA card (or
at least has that size/style looking connector).
The only writing on it is MPPi Ltd. There are no connectors on it, not
even a case dust plate for filling a blank slot (so they must have
planned on you leaving the slot cover in place when this was inserted, or
it isn't an ISA card).
There are 4 chip sockets on it, with the 2nd of the 4 containing an EPROM
chip (M5L2764K). Remaining chips appear to be maybe support chips (SN74L
series chips).
There is a small bank of 4 dip switches, and two clusters of jumper poles
(no jumpers installed, poles are labeled A thru G).
Anyone have any clue what this card is? I'm wondering if maybe it is an
early security dongle. Maybe this was done as an internal card rather
than an external parallel or serial block.
