Maybe I overlooked it, but I missed a mentioning of ladder logic [1] that was often used in process control devices (even in those for homes, I've seen some of those still in use).
There's an obvious translation from the ladder logic to a MC14500B program, so it's easy to replace those devices with a simpler MC14500B device.
I even think I've seen ladder logic mentioned in some of the MC14005B documentation (but it's been some time since I looked at that).

- kens 6y agoI originally mentioned ladder logic briefly, but I figured nobody would be familiar with it, so I cut it out. The documentation discusses ladder logic a lot (as you remembered), and how to convert from ladder logic to the MC14500B: http://www.bitsavers.org/components/motorola/14500/MC14500B_Industrial_Control_Unit_Handbook_1977.pdf http://www.bitsavers.org/components/motorola/14500/MC14500B_...
- djmips 6y agoMy father and colleagues were still using ladder logic at the paper mill they worked at as of the nineties. In an article on PLCs as of 2016 they claimed that ladder logic still dominated... According to this article link Ladder Logic still makes the top 50 languages. OK so it's 50. https://spectrum.ieee.org/static/interactive-the-top-programming-languages-2019 https://spectrum.ieee.org/static/interactive-the-top-program...
