Nice shots, B, where did you find them?
An EPROM makes sense:
__I've seen tiny ROMs used for mapping memory configurations in 2-4 Chip arrays of 32k & 64k EPROMs in Font Cartridges
__in one of his Cookbooks, ISTR Don Lancaster describing KBD remapping scheme using only an EPROM & support glue
If there are three addressing control variables on the LC PDS, the ROM could easily be remapping slot access in real time, I wonder what the driver might look like.
With a simple manual switch setup, the same thing could be accomplished, I still wonder what a driver might look like . . .
. . . or if one might be needed? :?:
