One of the most historically significant operating systems that?s likely to be in the ?not

where the principles of ring based design and synchronizing by semaphores was invented.)
Maybe, just maybe, it might exist in the form of listings, and since it?s a fairly small
body of assembly language code that might be good enough. Then there would be the problem
of the emulation, though I do know one is being worked on, and at least one real machine
might also still exist.
Come to think of it, I recently read a document about the first Algol-60 compiler ?
consisting of a design description, the full (assembly language) source code, and a Pascal
equivalent.

There is a large class of big machines where this is true. Hell, it's even true
once you get away from the popular minis. Try finding supermini or array processor

Al,
From my standpoint the OS that comes to mind is GCOS-8.
