CNC like machinery was available for a long time. In the early 70's, it was done with 1'' wide perforated paper tape. Not unlike the old punch cards for the early ENIACs. The tape had perf holes, and not unlike a player piano, the tape was ''read'' and the parts reproduced.
Thanks Dave for the insight. Never ceases to amaze me what folks came up with back then. It was once the state of the art and did everything we needed. I bet it still would if you had the machines and tuned them up... try doing that 40 or 50 years down the road with anything we make today...
My programing ended at C+, with a little Arduino time thrown in for laughs. People say computers are unintelligible... but there are plenty who say these little engines are just as bad. I for one am grateful to only be confused by tax law and my wife.
I'm being a little wordy perhaps... You'll have to excuse me. The sakura blossoms are out and the sake has been flowing at the picnics... There's that progress again, saving me with spell checking.
