Proms

nThe numbers of the Intellifont PROMs (MR40, MR41, MR42, and MR43) correspond to the socket numbers printed on the controller board.

nBoth the PROMs and their sockets are notched on one cor- ner to identify correct orientation: notch to notch.

nIf you meet resistance when inserting a PROM in its socket, recheck the orientation of the PROM.

Caution: Do not force the PROMs into the sockets.

Make that each PROM is in the correct socket and that the notched ends of the PROMs match the notched ends of the sock- ets.
