It's not clear yet how much data is available on
the architecture of the
Combitron. However, I am working with contacts to try to get as much
information as possible. If enough data can be found, and an
operational example of one of these machines can be found, it shouldn't
be too hard to "dump" the microcode
there's a working one here:

It's also possible there may be one in the artifacts CHM received from
Germany last year.
