As far as automation goes, I retired about the time customers wanted

build real time control systems with Windoze :-).

Try that with a 6 station press line with interfacing "Gandy Dancers"
that is knocking out 58 hoods an hour.

Programmable controllers can handle the individual presses as well as

Co-processors running on OS-9 got the job done.

Those with a preference for ModBus AKA: "Turtle Bus" or Windows were
