I recently answered a question about how a specific circuit worked and I was so intrigued that I just needed to write down my findings and share it.
The circuit uses a single (cheap) push-button to make the output toggle with debouncing and no-delay switching. The circuit used originally two NOR-gates and was embedded in a mixer-table. I boiled the circuit down a bit to get to the bottom and this is the result
The original NOR-gates were used to be able to do predictable power-up behavior as well as global set/reset functionality. The elegance of the circuit is brilliant IMO.
A full write-down and timing-diagram is on my homepage at Vagrearg.org Have fun looking and enjoying pre-microcontroller era ingenuity.
