I don't think that was the point of what she was saying... I think it
was that although the *BOX* said 11/53, there was actually an 11/23
plugged into the bus. I can understand that might be the case nowadays,
with all the moving of boards and such... but I cannot believe that
DEC ever marketed a machine which said 11/53 which might contain an
11/23 processor... someone surely would have noticed and had a problem
with it...
