ATonce Plus
I went back and looked it up – NOP is hex 90. I wrote a program and
uploaded it into library 12 here. NSOUND.COM – self extracting archive.
Includes source and documentation. <btw> it's OUT 61h,AL, not OUT AL,61h.
I got it mixed up. I hope this helps.
p.s. Have you got any info on when/if Vortex will have the software update
for EGA or VGA 16 color ?
