If it's not a Cromemco, it's crap
@scott Reminds me of another Unix clone https://en.wikipedia.org/wiki/Coherent_%28operating_system%29 I ran for awhile back in the early ‘90s on a 286. Using dial-up UUCP to a local Coherent site I was able to get “free” access to Usenet groups and email. Speaking of UUCP, apparently it’s being used over HF in a Brazil emergency net system https://www.rhizomatica.org/hermes/. Another ham radio rathole to go down!

@VE1KM I never had the opportunity to try Coherent, maybe it would be a fun rainy day project to get it going in a VM.

I was reading up on Crememco, because I didn't know much, I just liked that ad that I posted the pic of, and they were a pretty serious player back in the day.

@scott IIRC, Coherent was something like $99 USD. Linux was considered immature at the time and required a 386. It also had an excellent manual which was a great reference for lex, yacc, etc. Only recently tossed it while purging for a move.
