A square wave on 352 master gain orthogonal to the spiral sweep would do that with a swept spiral.

Sorry about the clash of frame rate and sweep speed, but here at last is a demonstration of the panel being played. This includes swept spirals, PDM blanking, CYGN-A, CYGN-B, and a spiral within spiral effect using four quadrant multipliers.

Two things not shown in this video are that, but it's coming. I'm trying the bela oscillator bank class for this. And the licks near the beginning where the variable sweep rate control is brought down and then up aren't there, but only because I forgot to turn the dial, and can be dropped in.

🎯Excellent progress, Greg!
👏👏👏

What goes around, comes around;
We project what others reflect.
Nice............

Here's a link to the now complete tribute to the L.A. Woman laser show number. Here's a second link to the original number which served so well as a measurement against which to calibrate the emulator. The dogloids featured mid song are true dogloids generated new by the Commodore 64, and size changed through the master gain on the panel. By embarrassing mistake I brought the dogloids down to dots in the mojo risin sequence climax. Obviously the logic of when they come in is working correctly.
In the current system, scripted show editing cues are taking the place of the override switches.

For those interested, some Great words regarding the SAGE computer now exist. To summarize, there is a wiki entry for SAGE here:
https://en.wikipedia.org/wiki/Sage_Computer_Technology
Edited source material:
This image on wikipedia shows a huge computer, but the one of interest was a small shell with several dedicated boards and the controller included four function assignable shaft encoders.
The exciting vibe at the time (mid 80s) was the new 68000 processor, the core of the custom sage system discussed here. It could create a 'point output' rate much, much faster than alternate systems at the time. Plus, it did NOT have a 'reset point', a moment on every refresh that the computer stopped to think. Having no reset point meant the rate of anything could be sped up and it would stay solid, allowing smooth color-mod and chopping from the mk6b console.
Here is a 3D view of the Multabela Harness PCB currently under review prior to ordering. This replaces the current prototype which consists of a card cage with one soldered board, two wire wrap boards, three strips of bread board and a plate of spaghetti.
