These are 80′s-era erasable programmable read-only memories, or EPROMs. They were an immensely popular way to store firmware for embedded systems when the production run size or schedule didn’t make it economical to use less expensive masked ROMs. Then cheap EEPROM hit the market, and EPROMs all but disappeared from devices within half a decade.
