What this manual does not contain
[edit | edit source]The power supply board is listed only as a complete assembly ("Power Supply Board with parts", 5872-9539). There is no power supply schematic and no list of its components, so its capacitor values are not in the manual.[1] The manual has no table of diagnostic cartridge failure codes; it says that full instructions came with the Diagnostic Test Cartridge. Page 24 is headed "Disassembly notes" and is blank.[1]
