<blockquote>[[Val Garuts]] was project manager and developed the large signal amplifier circuit used in the horizontal and Z-axis amplifiers. [[Thor Hallen]] did the [[7A19]] plug-in and the vertical amplifier, and [[John McCormick]] the horizontal. The trigger and time base ([[7B92]] plug-in) were done by [[Les Larson]] and Bill [[DeVey]]. [[Bill Peek]] worked on the Z-axis amplifier and auto-focus, with [[Hans Springer]] doing the mainframe interface and channel switching. [[Joe Burger]]'s work on the power supply, coupled with [[Joel Swanno]]’s efforts in mechanical design, reduced the weight to only 30 pounds. [[Ken Hawken]] did the fine job on the CRT. </blockquote> | |||
