Two images stand out in representing Tektronix and its legacy.  One is the "Tek Bug" which first used a round CRT and was later updated to a rectangular CRT as shown on this front panel logo.

The other image is the "Wizard" which was shown on the vertical amplifier schematic in the 454 manual because this fast circuitry was magical.

The Wizard was also listed in the parts list.


The museum has a vintageTEK Demo Board for sale on our eBay store or at the museum which will draw these two patterns on an oscilloscope in XY mode.

This is a small (1.2 x 2.5 inches) circuit board with a processor and R2R D-to-A converters that will generate patterns on an oscilloscope operating in XY mode. The two patterns display alternately for a few seconds each. If you are an oscilloscope collector, or enthusiast, this is a great way to show off an analog oscilloscope.  A source of 5 volts at about 20mA is required (not supplied).

In fact, this demonstrator board looks great even on a competitor's scope as shown in this photo sent to the museum by a happy customer.


This board has been updated and now includes the capability of playing Table Tennis!


Here are some enthusiastic kids playing tennis at the museum on a 465 oscilloscope.


Alan Wolke on his w2aew YouTube Channel uses the demonstrator board to compare differences in XY mode on analog and digital oscilloscopes.
