I both read the Soul of a New Machine book and used the Data General MV8000 hardware depicted there - a purchase of DEC VAX machines was being considered, but meanwhile an MV8000 and a bunch of blue and white terminals snuck in ...

The hardware was pretty solid, although I'm not sure anyone got around to doing custom microcode that was a selling point. The operating system (AOS/VS, was it?) was OK, but had some edge cases - I remember the filesystem had ACLs (access control lists), but you could create files owned by non-existent users (promptly used for a prank).

Thanks for the tale, it made a dent.
