Sorry, but those characters are _plotted_ dot-by-dot on the screen by 
BASICG from an internal table (_not_ the character generator!).
I tried using them with a simple terminal program and found that there
was too much interference between the port acceses for plotting the
characters and the port accesses for the RS-232. (It takes several 
OUT instructions for every dot in the character matrix!!!!!)

If you really want 80x24, get the Model 4 upgrade. It's only $99 now
(plus around $30-45 installation) and they will modify the hi-res
board to work with the Model 4 board. And you can still run your M3
stuff if you want/need to (and with a simple routine, you can run
them twice as fast!!)
