There is no reason that the counter has to be binary. I think there
are enough terms to do a 7 segement count using the output latches.
Load would require a binary to 7 segment decode. Just decode
in front of the strange counter.
Just thinking out side of the box.

Has anyone here worked with or ever plotted
silently to create a moderish
7-segment decoder/driver from a GAL16V8? I'm working on a project made
from classic parts, and am trying to reduce part count rather aggresively,
since I'm going to hand-wire it.
One thought was to attempt to combine a 7490 _and_ a 7447 in a single
GAL16V8. I have blown hundreds of PALs, but have much less experience
Do you need the driver to count?
I would decode the input and latch the outputs for the display
if you did not need a count.
Thanks for any nudges towards a solution.
