EAI TR-48 Analog Computer Module Configuration on York University Computer, As Built for Installed Board
A single large-format schematic drawn to scale by Josh Bensadon (September 5, 2012, revised October 10, 2012) documenting the module configuration and patch panel layout of an EAI TR-48 analog computer as installed at York University. The drawing identifies each installed module bay (amplifiers, attenuators, multipliers, and patch connections) with shunt types keyed by EAI part numbers (005-172 through 005-174) and resistor values ranging from 100K to 10M ohm at 1% tolerance. Revision notes record corrections to wiring for a board that came pre-installed and minor fixes to module naming and labels.
