The spec sheet from the PAL mfg. (signetics PLS173) seems to indicate
security fuses aren't an option on the model on my board. I have not
actually tried yet.
Failing that, if I can find one locally, there are only 12 bits of
combinatorial inputs.
I could easily whip up a little Arduino project on a breadboard to walk
thru all 4096 states and log the outputs for manual factoring.

Does anyone out there have one of these controllers?
There is an unprotected PAL- the address decoder- and I really need a
dump of it.
Many programmers, particularly the BP technologies ones, can
read it
Curious how you know it is not a protected PAL? The PALs are protected on
all of the CMD CQD adapters I have looked at. I can't remember if I
bothered checking the PAL on my CDU-720/M
