In the more "immediate" future. The wave multipliers are done and need testing.

WAD uses SAD1024, and frankly hens teeth are more common. The only way I was able to get a couple was.... to buy a WAD.

And just think, they used to have them hanging on a peg at Radio Shack. waah

and it's probably a good thing you can't see the price tag smile

In Australia they were $25 which was over a day's wage at the time, and as was Tandy/Radio Shack policy at the time, they were seconds. In other words, you paid $25 for a worthless piece of shit, and couldn't return it under their no refunds for semiconductors policy.

Nice as they sound when working properly, the SADs were unreliable from the jump.

Looks like the negative slew is back:

It would help if I uploaded the dang images, wouldn't it?

FYi- positive slew is now online:

I wonder if there will be a Smooth & Stepped generator. That was one of my favorites. Internally the two were exactly the same circuit. The panel layout was just different for the Smooth and Stepped sections. I reverse-engineered it (this was like 1978) and built a version with a panel switch for Smooth or Stepped for each one.

Yes, there is an SSG on the horizon.

Pos and Neg Slew are the ancestors of the Universal Slope Gen. What's the use of having them if there's a DUSG available, as well? Just curious.

I had built original Positive and Negative Slew modules around 1980 or so. I'm a fan of the Negative Slew. The Positive not so much, because it isn't that useful for doing envelopes.

I also built a DUSG.

Why have a DUSG and also a dual Neg Slew? Adding a dual Neg Slew gives you more functionality in a small space. Look at the complexity of the USG (or the VCS). Nice, but you still use it for one thing at at time. The Neg Slew does a few things very nicely. I use it as a falling sawtooth VCO/LFO, and it works great as a VC A/R generator. It's perfect for smacking a low pass gate.
