I will again when testing the new build, but yes, 5V per div on the scope shows clean flat +-15 and +5. The new one shown here is almost ready for testing anyway.

The new build of the SPGN programable ramp generator is working the way it's supposed to. Glad to have those signals back, and be able to move forward with some new experiments.

What drives switch A15 across the capacitor, I'm assuming it is the reset for the ramp?

The reset signal & direction & spiral/diamond signals go to a true compliment driver (CD4041) and the non inverted & Inverted outputs drive analog switches (IH5012)Originally Posted by mixedgas

Here's a video showing experiments using color mapping instead of color modulation, mostly. No 3D effects are enabled in this number.

I set my system to time machine mode and looked back at an original LII specimen of the kind of choreography I'm still trying to figure out. Note it is just using curve pong, no joysticks or input from me except the cycloid. It's here in this video if you want to see it:

I'm also reposting the previous video ZZ Top Goes To Egypt with a better ending that shows more of the CYGN-B performance at the important part of the song:
