Hello: Richard, I will say you already have
the answer. Use an I.C., 8 pins socket
with your old eprom, make a list from
all the adjusments. Then update, that
new eprom. With the list you made before.
I did this before several times, if -
your new eprom, is okey only needs ---
update. Where I live a new eprom is --
about 10 dollars.
Good Luck
