A friend worked in a small Burroughs shop (1700).  I think it wasn't
so much that not many peripherals were supported, but that the system
had a lot of device independence.  You didn't need a special procedure
for each device, but just pointed your program at whatever device you
wanted to use and let the MCP sort it out.  Also, there wasn't such a
plethora of file formats.  I always hated the amount of work you had
to do to access a program module (source or binary) on a traditional
mainframe system.  Mind you, given the overhead of each file (look
at the VTOC layout, for instance), storing each program module in
a separate file was simply not feasible in that environment.
