SEM Schematics

  • Scanned versions of the paper schematics are on our internal Google Driver.
  • High level wiring schematic with KiCAD can be found on this Github repository.
  • Gun supply schematic does not seem to be present (high voltage → 25 kV supply).
  • Video Processor schematic (852576) might be missing one page (not sure).
  • There is a small daugher board with ASSY-NR 852540 mated to the Data System Daughter Board, with no schematic.
  • Schematic 852916 (Apple Interface) seems to indicate an early integration with Apple 1 or 2 computers :)
    • Information about the Apple II Slot interface can be found here.
