If you’re looking for an interesting electronics project that combines something old and something new, this clever build combines a new Arduino chip to re-create a 1970s era microcomputer.
Long before there were GUIs and human friendly interfaces, hardcore computer enthusiasts were dabbling with expensive microcomputers. Mark Wilson set out to build a replica of the first commercial microcomputer. He writes:
Not long after discovering the Arduino it seemed to me it could be a fun project to re-create an early computer, one with just LEDs and switches. I looked at things like the Altair 8800 (1975) but it has 30+ LEDs and 20+ switches and seemed like too much work. Then I stumbled on the KENBAK-1 (1971). Perfect! Only a dozen LEDs and 17 switches. As a bonus it was the 40th anniversary of it’s introduction.
