back to article Turing, Hauser, Sinclair – haunt computing's Cambridge A-team stamping ground

King’s Parade in Cambridge looks like the last street on earth to have anything to do with computing. On one side is an absurdly ornate college gatehouse in yellow stone and King’s College Chapel, which combines the barn-like shape of a tiny chapel with the scale and detail of a cathedral. The other side is lined by tall …

    I remember Acorn

    My memories of Acorn:

    In July 1986, the first week I joined DEC, I was asked to go and install VMS on a MicroVax that Acorn had just bought. 83 floppy disks and it failed on floppy 72. So, get another set (another 83 diskettes) and try again the next week. The most boring time I have ever spend since joining DEC (and I am still at the same company although it's been taken over once or twice)

      I remember doing VMS installs & upgrades on 8" floppies (just about the time the Beeb confidently stated on their computing programme that, "no one uses these any more!"

      That is interesting, since you see hints of VMS exposure in Acorn's subsequent machines. *I AM SYST to log into an Econet server as SYST(EM), for example. Using $ as the root directory on disk filing systems.

      And in the way RISC OS picks up on the VMS usage of system variables with a $ in them, e.g. Run$Path, File$Path, Sys$Date, etc. in RISC OS vs. SYS$SYSPROMPT, SYS$SYSOUTPUT, etc. in VMS.

    EDSAC & buildings

    Thanks very much for this piece, very nice to have. There's one point where I'd question the accuracy, or maybe I've just misread the piece.

    When I was an undergraduate in the Computer Lab in the late 80s / early 90s, the stories I heard about the building of EDSAC and its successors, didn't relate to the location where the Arup building was later found. Rather, they related to a building, also on the New Museums Site, but one or two buildings separated from the Arup building. I don't remember what it was called, but its doorway is shown on a set of EDSAC reminiscences from 1999, which refers to it as an old anatomy lab. In my time, the terminal room was still used for that, complete with old racks for printout, and the mainframe itself was in the same building.

    But I haven't been back for 25 years so I may some of this wrong!

    Don't forget the bikes

    You should also warn visitors about the bicycles. In Cambridge, there are a *LOT* of them. Also, watch out, as many roads that are one-way for cars are two-way for bikes.

      Watch out because whether a road is two-way for bikes or not, expect to see bikes travelling in both directions. Also don't assume that all bikes stop at red lights, not even pedestrian crossings.

      (Note to the cycling lobby - I once almost got mown down by a van going the wrong way on a one-way street, but that wasn't in Cambridge.)

    I pass the old ARM offices on Market Hill often. There often a pie stall opposite and down (opposite M&S) that I can't leave alone.

    M&S in Cambridge is split into 2 separate shops and joined by what feels like a secret passage.

    I must take a little walk and have a look at the Sinclair offices, the seeds of my entire future were sown there. I will see if the people will let me look upstairs.

    There is an IT angle in the Kings College quad: there's a nice photo in August 1984's Acorn User (taken in 1980, with flares and everything) featuring Chris Curry and Hermann Hauser standing in front of the statue holding their new Atom machine - the precursor to the Proton, a.k.a. BBC Micro

      In Cambridge it's a Court not a Quad; Quads are from The Other Place ;-)

      But yes it's a great photo, so of its time.

      Re the pic on the steps of 4a Market Hill, L-R David Johnson-Davies ("DJD"), Hermann, Chris Curry, Roger (now Sophie) Wilson, Nick Toop, holding an Acorn Atom. 4a MH was never an ARM office; only Acorn.

      The Turing Room in King's is the College Computer Room as I understand it; named after the great man. But I don't think there's any implication that he lived in that basement room, it's a cellar. As a Fellow he might well have lived in the rooms above, though.

    Nope

    Acorn didn't 'design the first RISC processor' (although Archimedes was the first commercial RISC based desktop) and they didn't 'develop the technology with Apple' - the first ARM was an Acorn effort. Apple's involvement was funding ~40% of ARM, necessary as they wouldn't use 100% Acorn owned tech in their own products.

    1. VinceH Silver badge

      Re: Nope

      "Acorn didn't 'design the first RISC processor'"

      That's not the only problem with that bit of the article. As you say, though, the Archimedes was the first commercial RISC-based desktop - and that's probably what led to the mistaken belief that they designed the first RISC Processor. Just a little conflation.

      "and they didn't 'develop the technology with Apple' - the first ARM was an Acorn effort. Apple's involvement was funding ~40% of ARM, necessary as they wouldn't use 100% Acorn owned tech in their own products."

      Quite. Apple had nothing whatsoever to do with its original development.

      The other thing that jumps out is if you follow the timeline in the article, it reads as though Acorn designed the processor in 1986 - but the first ARM chip was brought to life in April 1985, with the project itself starting a year and a half earlier.

        Re: Acorn didn't 'design the first RISC processor'

        No, but there's a strong case that Turing did so. His ACE design done in late 1945 had very few basic instructions, among many other beautiful design features.

      There are many ...inaccuracies... in the article.

      "... Cambridge’s first computer laboratory on the New Museums Site – a place that has seen scientific discoveries including the discovery of DNA ..."

      Perhaps the discovery of the structure of DNA was meant (with the Watson and Crick model in 1953). Since otherwise the options for discovery are really either Friedrich Miescher - who first isolated nuclein (at the University of Tübingen), or Albrecht Kossel who purified the non-protein component of "nuclein", i.e. DNA (at the University of Berlin). I doubt either of these warrant blue plaques in Cambridge.

      Re: For the true Sinclair aficionado...

      Camputers (builder of the ill-fated Lynx) was also headquartered on Bridge Street. It was related to Acorn in the sense that it was a spin-off from GW Design, a company that had provided some PCB design services for the Acorn Proton/BBC Micro.

      There's also Jupiter Cantab - designers of thr Ace - but they were way out in Bar Hill, up the A14 (although that probablly didn't exist in those days)..

      Allso worth a stop-off would be the Cambridge Science Park to see Cambridge Consultants, which once counted Clive Sinclair and Robert Maxwell as board members and was something of a nexus of early Cambridge micro companies.

    "The world’s first general purpose stored-program computer was built a few hundred yards away"

    And there's me thinking it was the Manchester 'baby'

    The Manchester Small-Scale Experimental Machine (SSEM), nicknamed Baby, was the world's first stored-program computer. It was built at the Victoria University of Manchester, England, by Frederic C. Williams, Tom Kilburn and Geoff Tootill, and ran its first program on 21 June 1948.[1]

    And I'm pretty certain a certain Alan Turing wrote some of the programs, possibly for its successor.

      Re: "The world’s first general purpose stored-program computer was built a few hundred yards away"

      Let's have it from the Stanford Encyclopedia of Philosophy: The Modern History of Computing

      The first fully functioning electronic digital computer was Colossus, used by the Bletchley Park cryptanalysts from February 1944.

      Turing's 1945 report ‘Proposed Electronic Calculator’ gave the first relatively complete specification of an electronic stored-program general-purpose digital computer....It was not until May 1950 that a small pilot model of the Automatic Computing Engine, built by Wilkinson, Edward Newman, Mike Woodger, and others, first executed a program.

      The earliest general-purpose stored-program electronic digital computer to work was built in Newman's Computing Machine Laboratory at Manchester University. The Manchester ‘Baby’, as it became known, was constructed by the engineers F.C. Williams and Tom Kilburn, and performed its first calculation on 21 June 1948. ... Turing's early input to the developments at Manchester, hinted at by Williams in his above-quoted reference to Turing, may have been via the lectures on computer design that Turing and Wilkinson gave in London during the period December 1946 to February 1947.

      The first fully functioning electronic digital computer to be built in the U.S. was ENIAC, constructed at the Moore School of Electrical Engineering, University of Pennsylvania, for the Army Ordnance Department, by J. Presper Eckert and John Mauchly.

      Other notable early stored-program electronic digital computers were:

      EDSAC, 1949, built at Cambridge University by Maurice Wilkes

      BINAC, 1949, built by Eckert's and Mauchly's Electronic Control Co., Philadelphia (opinions differ over whether BINAC ever actually worked)

      Whirlwind I, 1949, Digital Computer Laboratory, Massachusetts Institute of Technology, Jay Forrester

      SEAC, 1950, US Bureau of Standards Eastern Division, Washington D.C., Samuel Alexander, Ralph Slutz

      SWAC, 1950, US Bureau of Standards Western Division, Institute for Numerical Analysis, University of California at Los Angeles, Harry Huskey

      UNIVAC, 1951, Eckert-Mauchly Computer Corporation, Philadelphia (the first computer to be available commercially in the U.S.)

      the IAS computer, 1952, Institute for Advanced Study, Princeton University, Julian Bigelow, Arthur Burks, Herman Goldstine, von Neumann, and others (thanks to von Neumann's publishing the specifications of the IAS machine, it became the model for a group of computers known as the Princeton Class machines; the IAS computer was also a strong influence on the IBM 701)
