Please see the pages at 16 Step Analog Sequencer Circuit for details
regarding circuit descriptions etc. This page is here soley as a vehicle
to present the new PC boards and support board purchases. The
schematic and PCBs presented here incorporate all of the
improvements and m
odifications shown on the previous sequencer
pages. Panel to board w
iring is presented here. Please browse the
entire page before ordering board to ensure you understand the
circuit and there is enough inform
