ABSTRACT
The RIM Punch program provides a means of punching out information contained i n selected

blocks o f core memory as RIM-coded tape via the ASR 33 Perforated Tape Punch or 75E High Speed Punch.
The punch program may occupy either low or high memory depending on the version used.

PRELIMINARY REQUIREMENTS

2.1

Equipment
PDP-8Qwith

2.2

its associated ASR 33 or 75E punch.

Storage

This program requires 61 (decimal) memory locations.

LOADING OR CALLING PROCEDURE

3.1

This routine i s loaded using the Binary Loader. See DEC-08-LBAA for a complete description
of the Binary Loader.

3.2

Calling Sequence
None.

This routine cannot be called as a subroutine.

USING THE PROGRAM OR ROUTINES

4.1

Switch Settings
The SWITCH REGISTER i s used to enter the i n i t i a l and final address of each block of core

memory to be punched.

4.2

Start Up/Entry
a.

Make sure ASR 33 or 75E punch i s on.

Set the starting address 0041 (or 7441 i f using the high-memory version) into the SWITCH

@PDP i s a registered trademark of the Digital Equipment Corporation.
1

The computer halts,

Set the initial address of the block to be punched into the SWITCH

REGISTER and press the CONTINUE key.
d. The computer halts, Set the final address of the block to be punched into SWITCH
REGISTER and press the CONTINUE key.

Note that the final address must be larger than the initial address.
e.

A block of leader (code 200) i s punched followed by the selected block of data in RIM

format

The computer halts.

as desired.

Steps c and d may now be repeated to punch as many blocks of data

To terminate the tape, proceed as follows.

g.’ Set the terminating address 0074 (7474) into the SWITCH REGISTER and press the LOAD

ADDRESS key. Next press the START key and a block of trailer i s punched.

DETAILS OF OPERATION AND STORAGE
Reference to section 7.1, Flow Chart, w i l l illustrate the following discussion.
After entry, a short subroutine i s entered to punch a block of leader.

Next the i n i t i a l ad-

dress i s picked up and the six most significant bits are rotated right, masked out, added to 0100 (in order
to punch channel 7), and punched.

The least-significant six bits of the address are next masked out and

punched.

A similar process i s followed to punch the data associated with the corresponding address except 0100 i s not added before the first character i s punched.

This process i s repeated until the final address i s reached; then the computer halts at the starting address.

I f more blocks of data are to be punched, this i s done as explained i n step f above.

The routine i s entered at a different address to punch the final trailer.

5.1

Execution Time

This routine i s output limited with respect to speed.
