(41C) RECKONERS - SlideRule - 08-10-2020 07:21 PM
An extract from RECKONERS the prehistory of digital computers, from Relays to the Stored Program Concept, 1935-1945, Paul E. Ceruzzi, Contributions to the Study of Computer Science, Number 1, Greenwood Press, 1983, ISBN: 0-313-23382-9
APPENDIX
Program Listings
Following are listings of original program codes written for the Z3 and ASCC. Each is then translated into a program for an HP 41C pocket calculator. While this calculator employs a logic quite different from the Zuse and Aiken machines, I have written the programs for it to conform as closely as possible to the logical flow of the originals.
I also include a 41C program that "emulates" the operation of the Bell Labs Model I as it performed complex division. This program requires a printer connected to the 41C.

The link says "Not available due to issues with content", which probably means that someone has filed a copyright complaint against the file. I am in the USA so it's not a regional issue.
