Unique id/year of acquisition: 100/99
Name: Paper Tape Library
Paper Tape Library
Class: other
Machine: CAP
Notes:
A selection of paper tapes containing subroutines which could be physically copied and stuck together to form parts of larger programs. This technique was common to most computers until the 1970s.
Correction from Martyn Johnson:These paper tapes were not a subroutine library and they were not joined together. Each paper tape was a standalone microprogram for the CAP. Mostly they are test programs of various kinds and some bootstraps. There is probably also a paper tape copy of the microcode that ran the normal instruction set of the machine, though in the latter days this was more normally loaded from disc or network.
