This board uses some different ICs from the rest, including some Texas Instruments op-amps. These amplifiers might be sense amplifiers for the signals from the core memory stack. 13/17

If you recognize my mysterious aerospace computer, let me know. Credits: Thanks to https://twitter.com/UsagiElectric for providing the computer. Patent diagram from https://patents.google.com/patent/US3201785A. AN/AYK-14 photo from a 1983 CDC brochure via https://twitter.com/bitsavers: http://www.bitsavers.org/pdf/cdc/military/an_ayk-14/AN_AYK-14_Brochure_Mar83.pdf Schematic from the datasheet: https://archive.org/details/TNM_Various_circuits_-_Signetics_Corp_1966_20171106_0030/mode/1up 16/17 My previous thread on this mysterious aerospace computer.: @blterrible yes, I'm working on this system with CuriousMarc and TubeTime @kenshirriff That beauty is used to perform the precise calculations needed to avoid flying right through a star or bouncing too close to a supernova. @kenshirriff This looks so much like a CRM-114 from Doctor Strangelove... but it seems to me like either communications security, or guidance. Maybe, and I'm guessing: T/A = target approach, T/G = terminal guidance? It seems like a thing that might have been classified, but low-risk at this point. Good luck with your research! |
I couldn't determine who built this device. NASA used the same Signetics ICs in multiple computers, so perhaps NASA built this computer too. The ICs say "CDC" so perhaps Control Data Corp. built it; they built aerospace computers like this AN/AYK-14 from the F-18. 14/17
