Print values fast (10X faster)

Post by Bean »

I love the ZX81, but printing values is crazy slow.
Try this

10 FOR X=1 TO 200
20 PRINT X;" ";
30 NEXT X

So I thought I would write a short machine code program to make it faster.
I have timed it and it seems to be about 10 times faster than Sinclair BASIC.

All comments welcome...
