ZigZags by Noice, nice programs originally designed for 1K ZX81.
The original programs are
Noice-1.p (AKA Severely Limited v1)
Noice-2.p (AKA Severely Limited v2)
ZigZags is my full screen version.
Can anyone explain to me how these programs, Noice-1 and 2, even LOAD and RUN. There is absolutely no starting code that I can see.
There is no BASIC lines. Loading and stopping the program will crash the system. I LOADed the code to low RAM to disassemble and analyze.
Note, Noice-1.asm is my analysis of the program.
Enjoy;
Greg
Here's another interesting version.
Press a key, except "Q" which quits the program, will cycle through the Ireg values resulting in some interesting dislays.

It seems NXTLIN points to a line at 403C where there is a USR 16458 (8F 00 94 00 00). The ZigZags look very good with colours!

Thanks, that's a neat trick, I'll have to remember it.
