Dr. Scott M. Baker published a new build:
When I was first getting started with electronics, wanted a Heathkit ET-3400 Microproccessor trainer, but could never afford one at the time. Eventually both I and the world moved on, to fancier more capable computers. However, I’ve still always wished I had an iconic trainer, complete with LED displays and a hexadecimal keypad. So I decided to build something of my own.
Check out the video after the break.
