Where is the firmware on the 9895A? Is it in a 24-pin DIP package mask
ROM near the lower right corner of this picture?

Hmm, looking in the service manual it appears there were several
versions of the controller board. Some with multiple PROMs and some
with a single ROM, and some with a Z80 and some with an MC2
(micro-CPU, the '2' is a superscript).

I have a 9895A. Don't know which version of the controller PCB it has
without digging it out to take a look.
