Site information and index

I'm interested in computer history and reverse engineering old chips.

Some of my projects:
Restored a Xerox Alto.
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.
Gave a talk on reverse-engineering old integrated circuits at the Hackaday Superconference (YouTube).

reccism told me about you, airgapped ethernet, could LANCE type chips be programed to transmit over unused cables, made into transmitter antenna?
