A vintage bit of hardware out of something. My guess is a terminal of some sort. The program is stored in the EEPROM (or EPROM) in the socket. Very many electronic PCBs will have Tx, Rx and Gnd, using several different protocols. Nice to add to a collection of old useless brds, but probably not a lot else.

Sorry.
