The three phase Astable is now a seven step sequencer. When wired in order 1,2,3,4,5,6,7 the firing order is 1,6,4,2,7,5,3 then returns to 1 so it steps by 5. The sequence does repeat. This can be the sequencer and clock combined for IO2 the Inside Out Light Logic computer. No other clock will be needed.

Here is a good display of the sequencer in action and I realized that I now have a solid clock and sequencer in a single circuit. This will be used for the Light Logic computer project this winter.

I ran out of ideas other than adding a starter switch to the panel. On power up the loop freezes so I have to ground one input in order to unbalance the loop. Then I got the scope out and then the music fits the display.

That is a trace of cell one followed by cell six.

After I looked at the output traces, I wanted to see if I could sharpen them up a bit. so I added a Light Logic non-inverting buffer gate to the output of cell number one and the next video clip shows a big improvement. The lower trace is output number one and the top trace is the same output run through the buffer.
