We know that the CMT 64k RAM module is comprised of two 32k modules and gets configured as two 32k ports. The CMT EPROM programmer also contains two 32k modules, but it can be configured as a single 64k port by flipping the switch on the front. FRAM71 accomplishes this by manipulating the Last Chip In Module (LCIM) bit in the Config Buffer entry.

I presumed that the 64k "module" in the 71 came from a 64k front-port module, but I'm curious if/how it's possible to configure as a single 64k port?


What Mike has looks very much like 2 CMT 32K modules sandwiched together.
