   this discrete transistor computer project has been going for me since 2013

   a lot of it came from reading digital computer electronics by an author named malvino.

   computers are just switches made of an electronic component called a transistor. when i mastered this i was incensed: i have to build a discrete transistor computer.

   i eventually decided in 2017/2018 to change the design to something based on this: https://hackaday.io/project/4237-mental-1-a-brainfuck-cpu

   this project is in ICs, and is just small enough to be possible to solder by hand--i thought to myself: i can reproduce this in discrete transistors.

   the benefit of it is that is has no registers, so it simplifies the design radically.

   the big problems are that i have no idea what is in this guy's instruction ROM, and it has no stack, meaning it must 'scan'--it must unwind every loop instruction, making it horrendously slow

   i have seemingly lost my soldering iron, and entire kit of breadboards, so for the time being i will content myself with learning how to design and manufacture PCBs

   PS--i will try and do a writeup on how the design works, and make project logs
