So, this isn’t exactly retrocomputing and it looks like it’s from four years ago, but I just found it and thought that many here may find it interesting.

This guy built a simple 8-bit CPU out of essentially discrete logic circuits (from what I’ve see so far, nothing more complex than a 4-bit adder chip) and explained the entire process.

    Unlike me, you should talk to @amszmidt. What do you think about the existing port/emulation of the 1985 LM-3 #MITCADR to #HDL as a starting point for a modern lisp computer (instead of the scheme things that happen sometimes)? (I’ve tried and failed to get involved because of excuses. ;_;).

    I forgot the LM discussion of Actually Using The Extra Bits Available.
