SYSTEM INPUT/OUTPUT DUMP


DESCRIPTION 

The System Input/Output (SIO) Dump routine prepares a single binary tape contain-
ing the System Input/Output drivers, the significant locations in the System Linkage
area, and, optionally, a standard software system.

The SIO Dump is an absolute program which is loaded by the Basic Binary Loader
after the appropriate SIO drivers are loaded and with related channels assigned. 
a software system, for example, the Symbolic Editor, the Assembler, or Pass 1 of
FORTRAN, is to be included on the tape, it is loaded before executing the SIO Dump
routine.

The binary tape always includes the following:

        The System Input/Output drivers

        The contents of locations 101-104 and 106

        The contents of location 5

If the standard software system is also included, the tape contains the
following additional data:

        The software system (the contents of 107 up to
        location defined in 105)

        The contents of locations 100 and 105

The binary tape is produced on the device assigned as the Standard Punch Output
unit. Multiple copies of the tapes may be obtained if needed.

OPERATING PROCEDURES

A. Set Teleprinter to LINE and check that all equipment to be used is operable.

B. Load the Teleprinter driver tape using the Basic Binary Loader.

C. Set Switch Register to 000002. Press LOAD ADDRESS.

D. Set Switches 5-0 of Switch Register to he channel number of the device asso-
   ciated with the driver (the lower numbered channel for the Teleprinter).

E. Press RUN.

F. Repeat Steps B through E for the Punched Tape Reader driver.

G. Repeat Steps B through E for the Tape Punch driver.

H. Load standard software system, if pertinent, using Basic Binary Loader.

I. Load SIO Dump tape using Basic Binary Loader.

J. Set Switch Register to 000002. Press LOAD ADDRESS.

K. Set Switch 15 to 0 if binary tape is to contain SIO drivers and System Linkage
   only, or set Switch 15 to 1 if software system is also included.

L. Press RUN.

M. To obtain multiple copies of tape, repeat from Step J.

While the binary tape is being punched the following halt may occur:
