Ken Thompson keynote

Ken Thompson co-invented Unix starting in 1969 at Bell Labs in Murray Hill, NJ. His colleague was Dennis Ritchie, who also invented the C programming language and who passed away in 2011. They both worked with Brian Kernighan, who interviewed Ken Thompson on stage at VCF East. Extra points if you’re familiar with the inside joke in the historic C code on his shirt!

Counterpoint C-19

This was the rarest computer on display. Counterpoint was a company formed by former Convergent Technologies employees who designed a workstation called the C-19 to be resold by AT&T. Very few were built before AT&T canceled the contract. VCF members, including Anthony Stramaglia and Jason Perkins, restored this one into operating status.
