Comment Re:Maybe they're right, maybe old OSes never die (Score 1) 875
Are there any systems still around running Xerox CP-V or its descendant, Honeywell CP-6? They were both pretty slick systems for their day. CP-V was so stable and adaptable that in the early '80s Honeywell (who took over Xerox support) couldn't get their CP-V customers to migrate off their twenty-year-old Xerox mainframes onto modern Honeywell hardware running GCOS.
So Honeywell wrote CP-6 from scratch. They invented a language called PL-6 then wrote the entire CP-6 OS from the ground up. They liked PL-6 so well they rewrote their existing GCOS systems in it. Unfortunately, Honeywell never figured out how to market CP-6, and dropped support for it within 10 years. Bummer.
