Historic software at bitsavers.org

Although the majority of items at Al Kossow’s bitsavers.org are scanned copies of manuals, he also has software in source and/or executable form for a variety of machines (scroll down to “The Software Archive”) . Some of the oldest include MIT’s TX-0 and DEC’s PDP-1.

His manual collection also includes scanned copies of source code listings for some historic machines, including MIT’s Whirlwind and The University of Illionois’ ILLIAC I (scanned from hardcopies belonging to Wayne Lichtenberger).

Al notes that David Green is writing a simulator for the version of the ILLIAC built at the University of Sydney.

Update [when?]: TX-0, PDP-1, and ILLIAC I URLs following changes at bitsavers.org.

Update 2024/05/07: David Green’s URL via Internet Archive Wayback Machine.

  1. The story on the Kenbak-1 computer is told by the creator at the web site above. Included are copies of all of the manuals that were published by Kenbak Corporation.

  2. I worked on the Navy Univac 1219B computer and the shipboard equipment. I was fascinated at the manual for it I found on Bitsavers. What a wonderful thing you are doing. So many now just change cards for repair and have never seen an actual register. Can you imagine operational stepping thru a few instructions and watching the result appear in the accumulator register (upper). How can I help?
