12 Hole Paper Tape - CSIRAC Computer, CSIRAC to Elliott, T854, 1963 Document Reg. No: HT 13509 366

Summary:
Paper tape, part of a collection of paper tape programs and sub-routines used for input to CSIRAC. This is a program tape.

This program was written late in the life of CSIRAC, when users from the CSIRO Division of Building Research were changing over from using CSIRAC to using the Elliott 803 computer at Fisherman's Bend, which had different coding for its 5-hole tapes, so existing CSIRAC 5-hole data tapes in Flexowriter code had to be converted for use on the Elliott.

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:
Conversion Code transfer 1/5/63
