That was one of the main changes I would make if, in my dream world, I could actually redo the whole thing. Fortunately I have lots of 4136s.

The other thing is that it might be interesting to put sine shapers on the oscillators that form the Lissajous baseline. I don't know how it would look with an ellipse instead of a rhomboid.

This list is getting more helpful all the time. I need to get past Halloween before doing anything but after that...

Yep, I was a subscriber when I was in high school. I really wanted to build one. It only took me a couple of decades to get around to it.

The dog-eared magazine is in the next room right now. The pdf article on my blog is a recreation of the original, OCRed and reset in the original typeface.
