This board is a general purpose PROM (programmable read only memory) module compatible with the S-100 computer bus. The board has provisions for 71/2 kilobytes of ultraviolet erasable proms (EPROMs). There are also sockets for 512 bytes of random access memory (RAM). The board has a built in programmer that will program any of the proms on the board. The programmer does not need any special software. Any number of bytes may be programmed at a time.

The PROROM board is supplied ln several forms. Typically it includes one 6834 EPROM (512 bytes) and one 3539 RAM (256 bytes). A monitor routine is pre-programmed into the EPROM, which allows the user to perform basic functions with the host computer.
