The CDC CYBER 205 (a descendant of the Star-100 and the CYBER 203) allows
you as a programmer to decide how best to address your "file" space: you can use
the normal sequential file I/O, but you can also "map-in" a file to a
specified location in your virtual address space.  Another interesting element
of this architecture: the machine address all of memory using virtual *BIT*
addresses... 48 bits in every address!  Makes for interesting programming.
