Russel: I do not think You would believe some of the things that were done early on= .. A lot of things were developed by people and were never picked up by the=20 public. Back in early 1960 I bought a 541 Tek scope and developed a charter=20 generator for TV. I could display the letters and numbers on a TV. In early 1964 I= =20 sold it to The company(Brown Engineering) I worked for in Huntsville Alabama. All=20 their work was for NASA and the Military so they did not do any thing with it and in=20 1970 they sent me a letter giving the rights back to me. The problem was they were=20 making so much money on Gov. contracts they did not want to waste time and money on=20 something that was not sure. I am sure that there are many things developed early on= =20 that were state of the art and was never known outside of the person or small group that=20 developed it.

What is the mechanical"sequencer" for - shouldn't be necessary. Relays maybe. It doesn't look too hard to do with a fully analog system - even without relays.
