The IBM 1401

[Nan and Sandy Sanders]

I built a tachometer for my car in the late 1960s 
using a transistor from some surplus 1401 boards 
that were sold with the edge connectors broken off to prevent reuse.
Nan (KB4DAJ) learned to program on one.
There was one system in use in a government 
office I would go to until at least the mid 1980s.
