Watching my Model 28 with the cover off in action gets me hypnotized....

Modern mechanical engineers should take a look at what WWII Battleship
ead Reckoning ande Fire Control computers were like.
They are better art (and engineering) than what hangs in many museums. The
ven had mechaqnical integrators and, wait for it, differentiators. I was
tunned by the sheer cleverness.

 But, but, but...... those old timers were stupid compared with we
 smarty-pants engineers with our powerful 'pooters today! How could they
 possibly have done that?!?!? Slide-rules? What are those? Gee...your
 Agilent measuring equipment MUST be off, or not recently calibrated, or
 you
 read it wrong, or didn't have your glasses on, or your glasses
 prescription is
 out of date, or you're too damned old, or.....

 Crap! What a bunch of arrogant idiots!

 A "technician" friend of mine at a midwestern university bought an R-389
 from me some time back.

 His shop assistant was a young woman who was working towards a degree
 in mechanical engineering.

 When my friend unpacked the R-389, she sniffed and turned up her nose. It
 was too big, had too many of those ancient vacuum tubes in it, too heavy,
 and drew too much power, and was simply "not with it"....until he plugged
 it
 in, turned it on, and activated the motor-driven permeability tuning.

 Then her eyes bugged out, and her mouth dropped open, and she spent the
 rest of the day operating the motor drive and watching the slug-racks go
 up
 and down at different rates, and different directions, and different
 distances,
 and she didn't say another word.

 Too bad all of these modern engineers can't be taught a little humility...
