[ARC5] BC-221 Calibration

[Robert Eleazer]

"Then they used a machine that was used in banking to calculate and print loan payment books, and it would do the interpolation between calibration points and print the books."

Now that is amazing!  

Did you know that for checking out the wiring harness of the Atlas ICBM and space booster they used a DTMCO machine?  The Drive In Theater Movie Check Out machine was designed to do a continuity checkout of drive in movie speakers.  Hooked up at the drive-in it would do a continuity check and print out a report on which speakers were bad.  It did the same thing to the Atlas wiring harnesses right up into the 1990's.

So the Atlas inspired the development of WD-40 and a development of the drive in movie industry supported the Atlas checkout.
