This is the 24K RAM board for the Multifunction Controller. This card is used in early configurations of the MFC, where the RAM and PROM were on separate cards.

This card is used in combination with the 82408443-004 PROM board. The current version of the MFC uses the combined PROM/RAM card 82408667-001, which combines both the RAM and PROM into a single board.

This 24K RAM card uses battery 82408060-001 or 38002931-100 to maintain its RAM memory when power to the backplane is off.
