Talk:Ferranti Pegasus

I don't believe the Pegasus is the oldest running digital computer. At the University of Stuttgart there is still a running Royal/McBee LGP-30 from 1958. 173.140.90.72 (talk) 18:35, 22 August 2010 (UTC)

The reference I used (Early Brittish Computers) doesn't say what the differences are between the PEGASUS 1 and PEGASUS 2. --Bubba73 01:01, 4 Jun 2005 (UTC) The main difference is the Pegasus 2 had a larger drum. G4ugm (talk)

I've just moved this article from "PEGASUS (computer)" to "Pegasus (computer)" and decapitalised the name within the article. The reason for this is, consulting a Ferranti Ltd. sales catalogue from 1959, the name is not capitalised; probably because it is not an acronym and is merely a descriptive trade name. References to this machine might need correcting elsewhere. --NicholasTurnbull 21:51, 14 August 2005 (UTC)

I've just added two photos of the Pegasus, as it is in the Science Museum in London, UK... I have many others, also a lot of the original design schematics, etc... My grandfather was part of the team that built it.... Would anything else be of interest to this article..? --LeoNerd 21:10, 27 Nov 2005 (UTC)

A pegasus computer was in use for many years at C.A.Parsons, Turbine Manufacturers in Newacastle-upon-Tyne. Several hundred programs were written in machine code, autocode and in a high level matrix interpretive language. Towards the end of its life a simulation program was developed so that all Pegasus programs could run unaltered on IBM 360 Series hardware and so Pegasus programs lived on long after the pegasus disappeared. I seem to remember that the most diffuclt part of the simulation were the 39 bit divide instructions on the 32 bit IBM machine code set. Tony Momtague, 6th April 2006

Added info that there are least two surviving machines in London and Manchester (see Photo Discussion page), anybody know of more? --Adrian Mars (talk) 21:23, 19 June 2008 (UTC) The Manchester Machine has now been moved to the Science Museum Store at Wroughton G4ugm (talk) 17:24, 1 September 2019 (UTC)


 * The Pegasus at the Science Museum is run for a day each fortnight. I spoke to an ex-Ferranti employee who was one of the operators and he only knows of two machines - with the one in Manchester never being run. --Extols (talk) 11:23, 6 December 2008 (UTC)

The Manchester Pegasus machine was formerly installed at Brooklands Technical College, Weybridge, Surrey. In my final year of school in Egham - 1970-71, by which time it was obsolete technology - we had an optional course in which we wrote and ran simple programs on it, in assembler language. Input and output was via 5-hole punched tape. Running a program to sort ten numbers took about 30 seconds. We thought it was wonderful. 82.138.196.7 (talk) 19:44, 4 September 2010 (UTC)

SR53
The Saunders-Roe SR.53 is NOT a vertical takeoff aircraft. Either the text in this article means to say "first rocket-propelled British aircraft", or it is trying to refer to some other aircraft entirely. In either case, it's wrong and should be fixed.
