This is a sad day for us geeks.
Without Jack Kilby, it's doubtful that any of us would be here at MustangWorks.com at all, let alone there wouldn't be an internet, a computer, a handheld calculator, a cellphone...
Basically, anything with an integrated circuit owes its existance to him. How does this relate to Mustangs, you ask? Look what the EEC-IV, EEC-V, and Bosch computer systems have done for our hobby.
Godspeed, Mr. Kilby. You will be missed.
