[sdiy] OOOOPS!!!! (Top octave CPLDs)

[Tim Parkhurst]

Hi Other Tim,

Would it be possible to with the gates you have to generate and sum pulse
waves of different duty cycles to approximate a saw wave? You'd need some
post chip filtering depending on how close to a real saw you wanted to get,
but I think it would be more versatile to have one octave of saw (easily
converted to pulse or even tri) than 3 octaves of square.

Also, are you going to offer your TOG for sale? Sounds like a fun chip.
Might even make a few bucks. How about creating an adaptor socket to make it
a drop in replacement for existing TOGs out there like the S50240?

Okay, maybe I'm getting carried away here. Just a thought though...
