[Coco] EVEN MORE 1 BIT MADNESS !!

[Simon Jonassen]

Hey Art....

This is actually using the DAC.... But only 1 bit....

It could use $ff22 equally well, but i need $ff22 for other stuff....

What I am trying  to achieve here is sound and motion (in the form of a
demo) at the same time.....

I've been away from 8 bit stuff for far too long (20+ years) and even then
it was the 6502 / c64

So i just got back to 8 bit 6mths ago... And i grabbed my first computer i
shelved in favour of the c64... 

THE COCO II....

So what i'm upto now (while "re-learning" assembly) is trying to push the
limits...

I don't need to publicise all that i do, but if some of the stuff i do can
help others, so be it...

If not then just ignore it or put it in the spam folder....

Final note... No offence taken

/Simon :-)

Simon, could you refresh my memory (if you mentioned it before) what
advantages using the single-bit sound might have over the usual 6-bit DAC?
Or, are you just looking to establish how decent it can sound and whether
the processor demands can ever be minimized to the extent that it would be
practicable to use it in games?  (Which I don't mean in any negative way at
all--a lot of the fun of a CoCo is trying to push its limits.)  Right now,
it appears that the DAC has the advantage both in sound quality and
processor demands.
