Say nettimers -- is there anyone out there (or could anyone suggest an expert or
hobbyist or forum) who might be able to input into the process of restoring (and
eventually selling) a vintage vacume-tube-based (analog) computing device that I
have -- it's probably a primitive industrial loop-control unit with two racks of
15 tube flip-flops along with a rack of pulse (signal) controllers and such. It
was produced by a military-industrial company Engineered Electronics, Inc. in
Southern California (and related to the (George) Philbrick company, an MIT WWII
Rt. 128 spin-off)
The technology approximates the IBM SAGE device -- with modular plug-in
circuit-boards -- popular from the mid-1950s until they were phased out in the
early 1960s, replaced by smaller and more energy efficient transistorized devices.
Any input would be welcome! I can supply photos for anyone interested.
Cheers,
John
