Talk:EDSAC

message: When was EDSAC dismantled and/or scrapped and/or simply retired? Please add this information if you have it. -- 92.229.248.14 (talk) 11:10, 25 April 2010 (UTC)
thread_title:  Operational until when? 

message: For the EDSAC 99 celebrations, Cambridge and Manchester discussed the correct form of words for describing EDSAC. I believe that the form of words on http://www.cl.cam.ac.uk/conference/EDSAC99/history.html (6 May 1949) were agreed with Manchester as being correct. That is, that EDSAC was "the first complete and fully operational regular electronic digital stored program computer". Neil Dodgson (talk) 16:08, 16 April 2012 (UTC)
thread_title:  Was EDSAC first or second? 

message: There is no reference provided to back up the claim that the Manchester SSEM ran the first graphical computer game.  Unless this claim can be verified, surely it should be removed?  My searching on-line indicates that the first such game ran on EDSAC: http://www.pong-story.com/1952.htm.

thread_title:  Manchester SSEM graphical computer game? 

message: Wikipedia article claimed for EDSAC that "None of its components were experimental." but provided no references.

Herbert L Norris (Technician 1951-63) says:
"When working at the Engineering Laboratory (1940 - 1951), I produced a cylinder of brass about 3" diameter and 6" long, this was eventually to be covered by a ferrite material and to have a 'Head' travelling along it which was to read magnetic signals from this drum. I did not realise that I was in at the beginning of computers.
I was asked if I would like to join the Maths Lab in January 1951, and I was very pleased to do so. I never saw the drum working and I believe there was a problem with spraying the ferrite material on to give an even coat, and the development of the heads had not progressed enough to be run close to the surface."
- indicating that the mag drum store at least was indeed experimental hardware.
Donald Willis (Research Assistant 1948-50 & 1952-55) says that during 52-55:
"An experimental [tape] system was run on the EDSAC"
- likewise, some years after initial operation.
Therefore, I deleted this incorrect claim.

thread_title:  External links modified 

message: Unregistered User:Snowtrack and I have reverted each other's edits over this matter. User:Snowtrack has repeatedly changed the statement that "Work on EDSAC started at the end of 1946" to "Work on EDSAC started during 1947". This phrase is immediately followed by a citation to a source  which states that "Work on the project started at the end of 1946, and the machine began to work in May 1949." If User:Snowtrack has better information from a reliable source, it should be cited. --TedColes (talk) 09:44, 16 October 2016 (UTC)

message: "The early programmers had to make use of techniques frowned upon today—especially altering the code" I don't frown upon it this is a bit judgmental. --Kitchen Knife (talk) 20:25, 30 April 2020 (UTC)
thread_title: Self modifying code

message: The first paragraph states that the design of the EDSAC was inspired by that of the EDVAC. It seems to be more than just inspiration. Maurice Wilkes not only read the famous von Neumann's report. In August of 1946 he participated in a series of Moore School Lectures at the University of Pennsylvania about EDVAC design which obviously was an important influence. As a matter of fact, he produced the first sketch of the EDSAC design on his five-day return voyage by ship to England. Usage of delay mercury lines was proposed first by Eckart for the EDVAC. Even the name EDSAC is a reminder of this influence.Tsf (talk) 20:24, 4 July 2021 (UTC)
