about the system such as:  initial line speeds, system logical  names,
and magtape logical to physical correspondences.

3A-SETSPD version 3A(7) runs only on Release 3A of TOPS-20.

3A-SETSPD depends on the file PS:<SYSTEM>3A-CONFIG.CMD.

whenever one of the front end PDP11's is reloaded.  It need however be
run under timesharing.
