Not all of them are general purpose I/O lines. Anything that starts with 'PT' is, though. You *can* control them through the scripting language, but it requires using the POKE command and looking up the addresses in the MC908AP64 data sheet. Also, the LCD code will be trying to control 6 of those lines.
