<blockquote> | <blockquote> | ||
When transistors started to become practical, Tek sent [[Bill Polits]] to Michigan, for a 2 week primer on transistors. | |||
He in turn communicated it to the rest of us who were interested. That called for a transistor curve tracer. | |||
It used a similar step generator as the tube curve tracer but otherwise needed mostly new circuits. | |||
I remember a day at the beach, I was trying to hide from the sun while everyone else was getting their sunburn. | |||
I dug the sand out from under our new 1954 Chevy, got comfortable and figured out the circuits for the curve tracer soon to become the 575. | |||
[[Deane Kidd]] did the hard part when he designed the switches. | |||
