-imm6-26 PROM Memory Module
-
-This card has sockets for sixteen 1702A or similar 256×8 PROMs providing
-up to 4KiB of program storage. This card has additional features for
-INTELLEC 8 systems, including module select lines and DIP switches for
-mapping PROMs in place of console RAM. These features are not emulated
-by this class.
-
-In theory you could populate any combination of sockets, and use
-multiple cards provided you don't populate corresponding sockets on two
-cards. To simplify things, we assume contiguous sockets are populated
-starting with PROM 0 (A2). In practice, you'd want to populate this
-socket as the boot vector is at address zero. If you want to simulate
-unpopulated sockets, just zero the corresponding area in your image
-file.
