I got the boards back, and Charles’ version with just two D FFs and a single XOR works perfectly. It works even without the delay line he indicated
I have never needed the delay in practice, either (I use mostly NC7SZ, 74AC, and 74HC logic). Modern logic is vastly more forgiving WRT setup and hold times compared to the bad old days. I showed the delay just in case someone built it without and it didn't work.
What specific chips did you use? Best regards, Charles _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
