Robert -
wasn't there a lawsuit between DEC and MSFT over what went into NT?

I don't remember that. I certainly don't recall and charges of code stealing.

Prior to leaving DEC in 1988 to start NT development at MSFT, Dave Cutler was heading up a program called 'PRISM' at DECWest. PRISM combined hardware (including a fast 64 bit RISC processor) and innovative software, the core of which was code-named 'MICA'.

DEC later claimed that portions of MICA ended up in NT. They threatened to sue MS and also Cutler individually.

It never went to trial, so the merits of DEC's claims were never tested, but there is no doubt that NT owes much of its heritage to the design thinking that Cutler did for RSX-11, VAX VMS and also for MICA.

Designing from scratch does not mean ignoring the 50 years of thinking about how computer systems ought to operate. NT is certainly not a 'derivative' OS in the way that Solaris or HP-UX are. The only major UNIX which comes close to a 'from scratch' effort is DEC UNIX, which was based on Rick Rashid's MACH kernel rather than the AT&T / BSD UNIX.
