A forum post I read sugg= ested those involved were some former Bell folks from NJ. In any case, this= begs the question for me: Were there ever any serious attempts at an 8-bit= UNIX in the labs or Bell System at large? Certainly it would've provid= ed quite the challenge without much return compared with 16 and 32-bit effo= rts, but does anyone know if, say, an LSX/Mini-UNIX-ish attempt was ever ma= de at the 6502, Z80, or other 8-bits? Thanks all!
FUZIX is one that I'm aware of, but it's a rewrite, no= t a port: https://hackaday.com/2017/04/16/z80-fuzix-is-like-old-fash= ioned-unix/
