rewriting legacy OS for new iron

[Ron Hudson]

Would there be any interest in re-writing somthing like RSTS/E, ITS, 
TWENEX or one of the other
legacy OS to work on x86 machines? The idea would be to do something 
like Linux has done for unix but for one of the other OSs, I think all 
the ones I mentioned ran on pdp machines, whatever we choose to write 
could have once run on anything.

The new OS should be entirely self hosting. What would be the most 
interesting old OS to do.

This would differ from the simh machines in that actual serial ports 
would connect to serial devices and printers would connect via parallel 
port.
