The initial design work on the 3S76 was done by [[Cliff Moulton]]. | |||
It was called the Type 76, later renamed 3S76 before going into production. | |||
A decision was made to demonstrate the 76/3S76 at the 1961 IRE show. | |||
This created a panic because the plug-in was not complete. | |||
The 76 project landed in the TV group. | |||
[[Ron Olson]] and [[Charlie Rhodes]] were designing it and [[Walt Lowy]] was a technician. | |||
[[Phil Crosby]] worked in it for a week during spring break from Portland State (college then, not university). Phil Crosby designed the channel switching circuitry. | |||
