He and I go way, way back. If you have any information or updates please send me a PM or respond here...

    Yes, Laser Images used AD533 chips originally on the Mark 4, designed the 2QMM circuit and used it in many places, and built up the z axis rotators for the Mark 6 using AD532 chips

They are 6 legged devices looking like a small transistor. The power supplied is positive only, 15V. I thought maybe they were dual transistors...

    The sillyscope agrees: color mod 2 is bipolar. Do I understand correctly from previous posts that that the 4QMM is either AD533 or AD532 chips, and the 2QMM is a two quadrant multiplier module that Laser Images designed? I'm going to post a discussion found online that mentions the AD811 and...

    laserist replied to a thread CYGN-B in The Lounge
    I think color mod 2 was bipolar so amplitude modulation would have been interesting. With a 4qmm you could either modulate with the reversal or put a precision rectifier in the signal path. I want to build a box to do laserium style color mod slash chopper with The Radiator - I'll post it when and...

    There was exactly one 4302 in the Mark 6. It was one of the mods that were done over the years. It was a ramp shaper for the spiral ramp signal. I didn't like the shaped look and almost always kept the control at 5 to yeald a linear look. I have one of them, I'll put it in the next shipment...

    Brian, I remember, as you do, that the 6th button for CM2 applied FM to CM1. I believe the source for the FM signal was either the sum of the CYGN-A or just the C oscillator of CYGN-A. Hard to remember these details after 22 years NOT performing shows! The wiring may be in the blue-binder. I...

    The six buttons over the beam torquer knob on the Mark 6 control panel selected the CYGN-A Osc 1, Osc 2, Osc 3, Spiral ramp, and color mod 2 ramp to the color mod 2 gain control. The last switch ( as I recall) killed the color mod 2 output and shunted it into the color mod 1 Vco input for frequency...
