I was doing some sequence routine programming in Assembly, and recalled the old method of mechanical sequencers.
Not sure if anyone remembers or are familiar with them, but I oddly I could not find any reference to them on the WWW.
The typical one had a drum with rows of raised points on it and as it rotated slowly or indexed, the points would close a contact in the circuit, in order to activate it.
It was a simple form of pre-PLC control etc.
Anyone recall them?
Or have a link?
