As you will have gathered my interest is in their paper tape readers, and to date I have found nothing better than the maintenance / operators manuals.
PEC schematics, and listings/source for their final reel to reel would be paydirt Best Regards Martin -----Original Message----- From: Jon Elson via cctalk [mailto:cctalk@classiccmp.org] Sent: 17 January 2025 17:04 To: cctalk@classiccmp.org Cc: Jon Elson <el...@pico-systems.com> Subject: [cctalk] Re: Fanuc Tape Reader PECs 1980's - Connector Identification On 1/17/25 10:43, Nigel Johnson Ham via cctalk wrote: > I may be clutching at straws here, but Fanuc was a GE company, was it > not?

GE's CNC controls were insanely old-school, their Mark Century controls used hundreds of boards with Germanium transistors to do tape NC control. If you wanted linear interpolation, they added about 100 boards. If you wanted circular interpolation, they added several hundred more! They eventually did put their own computer logic in their controls, but they were years behind the times. Fanuc brought in 8086-vintage processors to the mix. The partnership was dissolved in 2009. Fanuc made some really great motors and encoders, but tried to make everything secret and proprietary after the early 1990's, which made retrofitting older machines quite difficult. Jon
