I'm building a computer around a DEC J-11 CPU, from first principles, that is, only parts datasheets, not "just" recreating a PDP-11 compatible machine. I'm hyper-focused on it, so much I'm starting to think in octal and gate logic. It's great fun, even if nothing comes out of it in the end (except much wasted time and money). Actually, my machine WILL NOT run unmodified unix, nor do I plan on porting it, I want to write my own, single-user system for it.
