My last message vanished. Not my day. The problem returned. It is not
stopping but slowing. 4000 hex bits input to column C takes 42
seconds. There are a total of 32,000 hex bits (row) total. Not wvwn
the Z80 was that slow. I want to rewrite it without the tristate
stuff. I don't really understand it. It was an example by another
member here.
