> So in his spare time, [Berners-Lee] wrote up some software to address this shortfall: a little program he named Enquire. It allowed users to create "nodes"—information-packed index card-style pages that linked to other pages. Unfortunately, the PASCAL application ran on CERN's proprietary operating system. "The few people who saw it thought it was a nice idea, but no one used it. Eventually, the disk was lost, and with it, the original Enquire."
Sounds like this was pre-NeXT, or at least on another in-house OS. It would be interesting to see what it was all about.
The Wikipedia article on ENQUIRE says it ran under SINTRAN III (the standard OS for many Norsk Data mainframes in the 1970s-1980s). So not a CERN-specific OS, just one not known to many people outside European users of mainframes at the time.
