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)Reply

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)Reply

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)Reply

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)Reply

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)Reply

SR53 edit

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.
