MITS 88-PMC 2K PROM Board
This board was MITS first PROM board.
The board was a Programmable Read Only Memory (PROM) card, capable
of providing up to 2K bytes of PROM memory using either the 1702 or 1702A
type PROMs (8 bits by 256 bytes per PROM). The card is designed with
provisions for switching the Vcc power supply to reduce unnecessary power
consumption. The card could be set for 0 to 3 wait states to
accommodate different PROM speed devices.
