Maybe the 680 and it's basic isn't fast enough
for my program?
This is quite possible as interpreting decimal numbers takes a fair bit of
processing. You may like to try this ..
1 A=61456:B=61441:C=61457:D=1:E=0
2 IF (D AND PEEK(A)) = E THEN POKE B, PEEK(C)
3 GOTO 2
.. which should speed things up a bit.
