Dig Dug 2 - odd number steps defaults to 8
« on: November 13, 2018, 10:17:30 PM »
I've built two Dig Dug 2's, one about a year ago, and just finished another.   Both strangely have an issue where sometimes it will go 8 steps when the odd number step sequences are selected.  Meaning for step switch on 1 it goes 8 steps, switch on 2 it goes 2, switch on 3 it goes 8, etc......  First time around i thought it was the switch, cleaned it, the put a new switch in and still same issue.  Now a year later, new switch, new chips, same thing.

Just wanted to check if anyone ever experience this?  I have a few more CD4017's I'm going to switch out, but wondering what could be causing it.  Maybe a different D3 to get a higher voltage to reset?
