Agree about Varian trademark.
In 1937 the Varian brothers developed the Klystron tube.
In 1965 Eitel-McCullough (EIMAC) merged with Varian Associates, but in 1995 the EIMAC division was “spun off” (now part of CPI).
In 1999, the company was reorganized into three distinct businesses:
Varian Medical Systems Inc., Varian Semiconductor Equipment Associates Inc., and Varian, Inc.
The Card Edge connectors on motherboard are Sullins Connector Solutions, Inc.
