I have succeeded in programming one of the subject modules and it turns out it is pretty straight forward. The pads that the PLCC package EPROM are soldered down to, are actually vias that go through the board to corresponding pads on the under side and all that is required to program them is to make connections from these pads to a standard EPROM programmer. I made up a connector using pogo pins that have their sockets anchored between two layers of 0.05" pitch perfboard that I got from Digi-Key. I mapped the contacts to a "standard" 28 pin dip connector and was able to read and program the EPROM using my ancient Xeltek Superpro II. There may be problems with some programmers because there are resistors on the module that pull down the CE and OE pins so when powered on all the outputs are active and at least one of my EPROM programmers did not like this.
One thing to watch out for is it would seem that the commonly available images of ROM modules the 10 bit HP41 words are split into two byte with the byte containing the 2 MSB first and then the next byte contains the lower 8 bits, this is the opposite of how the CMT modules want the data arranged, they want the lower 8 bits first. I reversed the bytes by splitting the image, writing alternate bytes to two files and then merging the two files to get the correct byte order.
