The material is divided as follows: 'Set up General' 'Bootstrap I' 'Bootstrap II' 'OS1 Set up' The notes by…

Tagged folder of stencilled notes, information and routines kept as a manual for Modular One. Various dates

Bound folder of the program, with some manuscript annotations. n.d. Note: 'Exec. I' was the Executive program supplied by Computer Technology Limited with the P.R.G.'s Modular One machine. CTL would not supply the text of the Assembly Code program, so Strachey produced an unannotated listing from the Assembled binary tape.

Miscellaneous manuscript with decoded and annotated sections from CTL's Exec. I program, produced by Strachey from the unannotated listing, to see how it worked. Probably 1970.

Miscellaneous manuscript notes, all regarding decoding and annotating of CTL's Exec. I program, some with dates March-April 1970. One technique for describing what a particular subroutine did was to write an 'equivalent' BCPL routine, and there is a 2-page narrative note describing conventions to be used when doing so.
