Yes, Very ancient machine.
You would not have known it was a F-11 CPU unless you opened it up.
The LSI-11/23 also could have a programmers utility, which was why Microsoft used one to develop Its DEC version of Xenix. So the LSI-11 birthed TWO separate wanna be UNIXes. Venix ran on the 8088, Xenix ran later on the 8088. Venix ran on the IBM AT, Xenix Ran on the IBM AT. What was DEC doing while all this was going in in the UNIX wars?
Although that this claims pre-C89, it was at least 5 years earlier, and running the portable-C Compiler, apparently Xenix version was a bit better, but not by much.
Which now leads me to speculate that after Microshaft divorced themselves from Xenix, they may have left their legacy email server ( a VAX ) for the use of SCO to keep developing Xenix on.
- pjmlp 1y agoBeing a bit lazy to cross-check dates, maybe their OpenVMS efforts? I learned C before having access to Xenix, this was definitly before any portable C compiler, I imagine, because the book used RatC, a K&R C dialect. I read somewhere that originally Microsoft did not develop MS-DOS directly on PC hardware, rather they would cross-compile/assemble, maybe they were using systems like these?
