Trying to figure out what to do with the Value Line chips I decided to make a Persistence Of Vision text display, fitting in all the best bits of the ascii table.

The font in 5×7 pixels making the it 470 bytes including a smiley.

Ideally it wants a way of programming it without rewriting the whole program, perhaps a low speed soft serial on one of the Port2 pins, not sure yet.

The source file can be found here main.c
