This new revision of the Input Sequencer board only had some minor changes to it. During my over-haul of the cabling and connections, I realized I needed to pass a few signals through the input sequencer. I also thought I might need an extra reset signal out to some of the modules, so I added a Schmitt trigger output, but not populating it until I actually need it. One think I might change in a feature revision is the decade counter. Right now I am just using a standard 4017 chip, but for looks, I think I replace it with a Dekatron Sim, like I did on the pulse generator module. Next step is to build up the Relay-D Latch boards....
