    Yes, this will be an ongoing problem. Audio has been removed, it should be accessible now. Here are more numbers. Look what was done using 351 in Soul Kitchen.

    Greg,

    If it's any help, I have included a link to the Laserock Platinum PIN sheets below, which give details about lots of settings, scan-glass placements, effects, etc. Sorry to have to do this as a link. This forum does not allow attaching PDFs to submissions.

    Ron, Your use of understatement is making me laugh. This unprecedentedly remarkable and timely scroll from your ancient library answers many questions and provides many fascinating and useful insights. You have made a forensic laser show archaeologist very happy.

    We've got the emulator. We've got the tape. We've got the notes. Let's rock!

    Picking a page from the previous spectacular doccument release: Run Like Hell, because no show steps are used. It was a scan only number, so let's try to remake it. I remember watching this number performed many times, and it was a predominantly red diamond kqo kind of thing, which both the data and the page describing the number mostly agree with.

    Something that doesn't quite add up for me is how effects were configured in the eight possible bus bit settings. For example, audio mod cycloid and triangle audio mod appear in the 351 data frame docs, but how did direct audio mod enter in to the signal stream?

    See page 44 of this thread for photos of the audio mod board tests.

    A more involved and more important uncertainty is the four A/B options FIXED CYCLOID, VARIABLE CYCLOID, SPIRAL/DIA., and INV. SPIRAL.

    If my understanding is correct, the only difference between spirals and inverted spirals is the use of the inverted ramp on the spiral board to make ramp-reset slam the image big and then diminish rather than slam small and expand. So I see diamond spirals and inverted spirals, but then where were non-inverted spirals?

    Again, if my understanding is correct, the fixed and variable cycloids, if to be modulated through the spiral board, had to be brought in through the diamond spiral or inverted spiral bus setting, and the spiral select switch was involved. I haven't yet located the previously posted information on what the spiral select positions were.

    I guess the best answers lead to the most new questions. Looking at the Run Like Hell page shown, I'm wondering how the oscillator bank settings figured into this number. Was the CYGN-A/B output summed with the input or output of the spiral board? Or are the signals used somehow for colormod and / or aom operation. I can guess that MULTIPLEXING A/O was rapid switching between different frequencies, but if so, I don't know about that part of the system.

    An interesting aside: a spin through the 351 data visualizer reveals that during Soul Kitchen, the bus settings are rapidly switched to create a double image temporally interlaced kind of effect. I have a couple of lines of code in mind that will allow the easy capture of this effect, so I'll be back with results from that.

    Greg,

    As a guide, I've extracted a (bad) video of "Run Like Hell" from the archive for your performance reference. You can download it here:

    (I didn't want to pollute my YouTube collection with this, and they'd probably copyright it away anyway. It's only 17MB.)

    You need to look at Laser Images' 351 data & signal path correctly. There were 2 bits to select what was on each bus and 4 bits to select the bus for the RYGB channels. So if you wanted spirals on RY and inverse spirals on GB you did that with the A/B bus select. Etc...

    That is all true. The visualizer and emulator software are fully and correctly making use of those eight bits. The uncertainty is in the Etc... part. Say I want spirals. The four RYGB bits are irrelevant because I have two bits each on A and B to choose an image source, and none of them listed in 6b-352_DATA-FORMAT.pdf is just spiral. There is Inv. Spirals, so OK, POKE 18, binary 00000001. That's inverse spirals. Where is Spirals? Was there a console switch involved?

    Please would someone remind me what the options on the spiral select switch were? I'm not finding it readily in my archive.

    Never mind. I was just confusing myself. it is in page 12 of 6b-ALIGNMENT_PROCEDURES.pdf. I see now, of course the bit is in the 351 frame.
