About Ken Shirriff

I'm interested in computer history and reverse engineering old chips. I am currently restoring a Xerox Alto.

Some projects: Wrote the Arduino IRremote library for infrared remotes. Attempted Bitcoin mining on a 55 year old IBM 1401 punch card mainframe. Got six symbols added to Unicode including the Bitcoin symbol (₿). Wrote an article on the first microprocessors for IEEE Spectrum.
