Whoa now this is really cool! I wonder if this would work in CP/M

Subject: [M100] triple screens

Making good progress on integrating the VT100 driver into REX.  A lot trickier 
than I expected!

Anyhow an interesting side effect -

Model 100/Tandy 102 can actually drive the LCD and 2 external screens at the 
same time.

Within a basic program it is possible to switch within a program using SCREEN 0 
(or 1 or 2).
0 = LCD
1 = RS232
2 = BCRhack(TTL serial)

So, I have this little demo running where I have text scrolling on all 3 
screens.
