[[ | <blockquote> | ||
Initial product planning and project coordination was provided by [[Leon Orchard]]. | |||
The mechanical design team for the 465 and 475, headed by [[Bob Rossman]], was: [[Neal Broadbent]], [[Bob Leith]], [[Len McCracken]], [[Bob Smesrud]], [[Ilmars Smiltins]], and [[Bob Twigg]]. | |||
[[Ken Holland]] and [[Bill Mark]] provided the attenuator design while [[Bob Johnson]] designed the [[P6065]] and [[P6075]] probes. Low-voltage power supply for the 465/475 was by [[George Ermini]], and [[Dennis Braatz]] designed the high-voltage supply. [[Connie Wilson]] and [[Gary Nelson]] did the CRT development. | |||
Electrical design team assisting [[R. Michael Johnson]] in development of the 465 was: [[Frank Dewater]], [[Pete Janowitz]], [[Dave Laib]], [[Al Schamel]], and [[Bert tenKate]]. | |||
</blockquote> | |||
[[Bill Turner]] worked as a calibration technician for the 465 oscilloscope group. | |||
