I was reading a paper by C. G. Bell from 1975 about what was learned from the PDP-11 in the six years since it was launched and I saw parallels between the computer industry in the 1970s and the solar industry in the 2020s.

This line struck me: “There is only one mistake that can be made in a computer design that is difficult to recover from—not providing enough address bits for memory addressing and memory management. The PDP-11 followed the unbroken tradition of nearly every known computer.”

@autumn hey Autumn I feel stupid asking such a simplistic question given the awesomeness of your project, but I would like some advice on how you connected the smd leds to registers (and buses) on the Sprout 24. Does each led have its own register and transistor?

I’m working on a “macro”-processor similar to yours and I would also like the Blinkenlights look but I’m kind of ignorant of how to run such a large array of leds. Any advice?
