12 Hole Paper Tape - CSIRAC Computer, Floating Binary. Basic Arithmetic, T300, 1955-1964 Document Reg. No: HT 13509 7

Summary:
Paper tape, part of a collection of paper tape programs and sub-routines used for input to CSIRAC. This is a sub-routine, a self contained unit designed to carry out a specific task within a program.

This tape was originally stored in Box B102 of the CSIRAC Program Library, which consisted of tried and tested paper tape programs and sub-routines (sections of programs). The tape is now stored with the other paper tape programs originally stored in box B102. The tapes stored in box B102 were T300, T301 and T302.

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.
