ABSTRACT
LOAD-14 is a program written in PDF- 8 language and run on a
Family-of-8 computer whose purpose is to load into 8 memory and
properly checksum a PDP-]^ binary program on punched' paper
tape via the teletype reader on the ASR-33 or the high speed
paper tape reader. This program is normally used to load PDP-14
It is NOT
tapes for use with the programs VER-14 and RUN-14.
used to load PDP-14 tapes for SIM-14.

LOADING PROCEDURE
LOAD-14 is loaded into 8 memory using the Vstandard" PDP-8
binary loader technique.

USING THE PROGRAM

3.1

Load LOAD-14 into

3.2

Place the PDP-14 binary tape to be loaded into 8 memory in the
paper tape reader to be used with leader (code 200 - column 8)
over the read diodes or sense pins. Turn reader on.

3.3

Set Switch Register to 7400, depress "LOAD ADDRESS".

3.4

Switch register settings.

3.4.1

If high speed reader is being used, set SRO to 0; if
ASR-33 reader is being used, leave SRO set to 1.

3.4.2

Set SRll to 1 if it is desired to load PDP-14 program into the
If SRll is 0,
locations indicated by the PDP-14 binary tape.
the PDP-14 program will be loaded into the PDP-8 memory starting
at location 0000.

3.5

Depress "START". The PDP-14 binary program will be loaded into
8 memory as dictated by SRll.

3.6

If the PDP-14 program loads and checksums properly, the 8 will
stop with 0000 in the AC lights.
If the 8 stops without 0000 in
the AC lights, reposition the paper tape in the reader over

memory using the Binary Loader program.

loader code and depress "CONTINUE".
Repeated checksum errors
indicates a "bad" binary tape or a malfunctioning reader.
3.6.1

If the PDP-14 program is greater than IK and it is desired to
load the complete program (only if SR11=1) , depress "CONTINUE"
after each segment is read in.

3.7

If LOAD-14 is in memory bank 1 and it is desired to load the
PDP-14 binary tape into bank 0:
Set IF switches to 1, DF switches to 0, SR to 7400, depress
"LOAD ADDRESS", reset SRO (if necessary), depress "START".
PDE-14 program will be loaded into bank 0 from bank 1.

4.
4. 1

DETAIL OF OPERATION AND STORAGE

LOAD-14 is basically similar to the PDP-8 Binary Loader with
the following exceptions:

4.1.1

No extended memory loading capability. LOAD-14 will only
load a PDP-14 binary tape into the memory bank indicated by
the Data Field switches when LOAD-14 is started.

PDP-14 binary tape will be loaded into 8 memory
starting at location 0000 through 1777 unless SR11=1.
If this is undesirable, tiie instruction in location
7423 may be modified as desired to alter this characteristic.

4.1.2

Tlie

4. 1 .3

The sumcheck of the information punched on paper tape is
the sum of the 8-ibit characters on the tape (excluding
leader/trailer, checksum, and text delimited by rubout codes)
plus the character count (number of characters added to
the sumcheck)
