Tektronix schematic draftsman redrew the engineers schematic for release in the instrument manuals. They must have had some jokers in the group because small cartoons found their way into some of the manuals and schematics. The schematic cartoons are subtle humor likely focused on the names the engineers gave some of the circuits or components. While we think we have found most of the cartoons, every now and then one of our restoration engineers shouts out from his bench that he found another. Send us a note if you find one that we have not. We are still looking for whatever instrument has this "Pilot Light".
Cartoons also found their way into other documents including the 1956 Employee Handbook and ServiceScope. Arnold Rantala was a draftsman and drew a number of early cartoons. The April 1965 ServiceScope featuring Spectrum Analyzers has a number of nice cartoons including some on this block diagram.
Cartoons also found their way into catalogs and other documents. This cartoon was found in the 1981 4051 GPIB manual 070-2270-00.
"Primitive Man" found its way into this Sony/Tek 1982/83 catalog on the 465B oscilloscope pages. The original cartoons were used on the slides for the 7854 introduction. Click on the image to view selected pages from this catalog.
This cartoon found its way onto the PCB of the 7V11 plug-in.
The date and use of this cartoon is unknown but is estimated to be around 1970.
One of the cartoons that was used a lot at Tektronix was the Wizard. The museum has a Tektronix Oscilloscope Logo and Wizard Demonstration Generator Board for sale on our eBay store or at the museum.
This is a small (1.2 x 2.5 inches) circuit board which will generate images on an oscilloscope in XY mode. The patterns are the Tek Bug (with the rectangular CRT) and the Wizard, which appeared on the 454 Tektronix oscilloscope schematics and it now includes the game of tennis. If you are an oscilloscope collector, or enthusiast, this is a great way to show off an analog oscilloscope.
