Thanks to everyone for the responses - and the new discussion, which
I'm finding quite interesting. I'm having a bit of trouble re: my
original question:

lda #255 ;max pulse width
sta $d402
sta $d403
sta $d409
sta $d40a
sta $d410
sta $d411
lda #64 ;select pulse waveform in control registers
sta $d404
sta $d40b
sta $d412
I'm asking because this is what I've tried, and it doesn't seem
to make any noticeable difference in volume for the digis. Thanks!
