Sb: Changing Screen Colors
Fm: Bill Wilkinson [OSS] 73177,2714

Okay, here it is at last. The
promised method by which you can set
your MAC/65 _CARTRIDGE_ screen colors
as you please.
.OPT OBJ
*= $483 ; CHAR.LUM = 10 BKGD.LUM
= 0 BKGD.HUE = 6 ;
.BYTE CHAR.LUM
.BYTE BKGD.HUE * 16 + BKGD.LUM
.END
That's it. Just type that in and ASM
it and your colors will change,
kerblang.
You might also (instead?) want to
assemble that to a disk file. Then,
to change colors, just BLOAD the disk
file.
Too simple to believe, right?
