Burroughs C-3350

This is a very cool calculator for a number of reasons.

1) It has a 16 digit Nixie tube display

2) It has core memory as a memory so it will stay there for years without power.

3) It was introduced in 1968 and contains ICs made by Mitsubishi. 

4) My first job involved working on Burroughs B7900 and A15 mainframe computers.
