Hello everyone:
this is very simple, could somebody please test the following code on
an Apple II? It is supposed to split-screen the display without
scrolling:
0300: A2 00 CA D0 FD A2 00 CA
0308: D0 FD A2 00 CA D0 FD A2
0310: 00 CA D0 FD A2 00 CA D0
0318: FD A2 00 CA D0 FD A2 00
0320: CA D0 FD AD 50 C0 A2 00
0328: CA D0 FD A2 00 CA D0 FD
0330: A2 00 CA D0 FD A2 00 CA
0338: D0 FD A2 00 CA D0 FD A2
0340: 00 CA D0 FD A2 49 CA D0
0348: FD AD 51 C0 4C 00 03 00
NTSC - yes, it does provide stable split.
PAL/Euro - not nearby to test, but I bet it won't.
And of course, my corrigenda:
34C: A2 41 CA D0 FD 4C 00 03
Cheers,
