FILENAMES: Tapeomat.gif Servoamp.gif DESCRIPTION: These are scans of schematics of an old Pratt & Whitney CNC control system. Posted by Brad Heuver . Brad provided the following description: ================================================================= Webmaster note - files were converted to .gif The two files tapeomat.zip and servoamp.zip are scanned .pdf files of the Pratt & Whitney tape-O-matic NC machine that was my early Christmas present. I hope to convert this machine to more modern cnc controls using EMC, a program that has been discussed a lot on the CAD_CAM_EDM_DRO email list at onelist.com. This machine has also been talked about a bit. The files are not very legible, unfortunately, especially the amp file, but if you want to see what the old electronic diags looked like, feel free.
