Update:
Hi again Guys,
I've done a few updates including support for a 250 character display message
for the scroller. This was done by making space for tables in program memory again.
Now the only thing other than a message on the on-chip EEPROM are game high scores and message length.

Removal of the external 12C EEPROM chip provided extra pins.
The serial port now has a dedicated pin, and a PCB speaker has been added.

Both games now have basic sound, and the unit clicks as you type characters into your terminal program
when using serial message programming mode.

Cheers, Art.
