I didn't look very closely, but I did go a little cross-eyed when I saw
the output from a NAND gate tied to an output from the PAL.  Didn't make
much sense.  I wonder if that's part of it.

Maybe I'm better off putting mental muscle into making my own upgrade
board.  Take advantage of newer parts (CPLD).

Thanks for the warnings folks.
