Has anyone ever tried to backward engineer the 2 ULA's ?? as they seem to cause problems..
I was thinking a CPLD should be ok for one of them.... what do you think??
but i have no idea how to reverse to know what is in the ULA's..
or..
I think 1G0003 can be replaced with a 8255A and several logic ic,
and 1G0002 can be replaced with a CPLD chip.
any help...
