The Atari Jazz Console video #4 is up ...

[Rykhaard]

This one gives a short / rough idea / showing of the 8 bit shift register in the unit as well as a small example of 1 of the voltage controlled SPDT switches, in use.

The last 2 modules that I'm looking at adding will include:

2 - Thomas Henry Voltage Controlled LFOs
and either
2 x CD4520 4 bit counters or
1 x CD4024 7 bit counter
to be used as (a) divider(s)

RichardC64 also showed me a GREAT example of adding voltage control to the 4023 'engines' based on Ray Wilson's method for doing voltage control to CMOS in his WSG! I'm going to try that on breadboard with 4023s. If it works as hoped, I'll be adding that mod., to the 3 'engines' in my AJC.
