Paper tape, part of a collection of paper tape programs and sub-routines used for input to CSIRAC.
This is a program written by Dr R.W. Muncey of CSIRO Division of Building Research for optimizing instruction addresses to get the fastest possible operation with the latest hardware upgrade made to CSIRAC (called Mode 3).
The collection includes the original University of Melbourne Computation Laboratory Paper Tape Library of 12 hole tapes of subroutines and programs, and program and data tapes from staff and outside users.
Most of the paper tapes were 12-track punched paper tapes. 5 hole paper tapes were used primarily for data input and output rather than program input. However, 5 hole program tapes could be produced by using Interprogram, an English language programming system rather than using machine language.
Each tape has a 'T' number. The Computation Laboratory Paper Tape Library consisted of tapes with a tape number less than 700. There were not 700 tapes but the number 700 was arbitrarily chosen to separate the Computation Laboratory Library tapes from user tapes.
Details of this tape:
01. Executive Non-stop primary

This is a program written by Dr R.W. Muncey of CSIRO Division of Building Research for optimizing instruction addresses to get the fastest possible operation with the latest hardware upgrade made to CSIRAC (called Mode 3). It uses the non-stop primary written by Muncey. Unlike other primary and controls there is no need to stop in the blank space between the primary and control routines to clear the sequence register and switch off the 'NA&S to K' switch. To use the non-stop primary it is necessary to set NA to 2 0 1 0 before starting.
