All those fancy-pants semiconductors... Here’s a real computer. http://web.cecs.pdx.edu/~harry/Relay/ http://web.cecs.pdx.edu/~harry/Relay/

  I took a compilers course from Prof. Porter, and at the time he invited undergraduates to write a simulator for his relay computer. I remember thinking, "why in the world would I want to do that? I want to work on the next big thing!" Fast forward to now, I've never worked on the Next Big Thing, and am instead slowly, though enjoyably, building Ben Eater's 8-bit SAP-1 when I have some free time. It sort of feels a bit like building a ship in a bottle. I just wish I had taken Professor Porter up on his offer and maybe scratched an itch when I had a little more energy and free time.

    I have been looking at your board on Tindie! Alas, I don't think it should be my first major soldering job (if you don't count the board I stuffed 25 odd years ago that my friend had to fix for me)
