Big Blue Marks Birth of Big Iron. The mainframe computer came into the world 40 years ago this week, and techies gather to mark the occasion. Daniel Terdiman reports from Mountain View, California. [Wired News]
This article is pure nostalgia, dealing with the event that defined my early years in the IT industry, the announcement of the IBM System/360 on April 7, 1964. A truly historic event commemorated:
Indeed, author James Collins has written that the System/360, along with Ford's Model T and the Boeing 707 jet, were the three most important business innovations of all time.
I spent seven or eight unforgettable years installing and supporting those early mainframes in mining companies in South Africa and banks and other international businesses in Greece. In those days there were no "IBM compatible" vendors, no consulting firms or independent software suppliers, in fact the guys who founded firms like SAP, Computer Associates and the like still worked for IBM.
IBM Systems Engineers like me did the whole spectrum of customer support: training the customers' embryo IT departments (then called DP, of course), educating and informing management of the potential, doing the systems programming while that profession was being invented, writing application software, problem solving and debugging and having a whole lot of fun, working with unforgettable people and making lifelong friends.
The pictures accompanying this story are a must for anyone who remembers those years; nice to see the grey-haired old guys who were responsible for the project smiling and reminiscing - even a reproduction of the indispensible System/360 Green Card, which was always in our pocket or briefcase, referred to constantly while doing Assembler Language programming, debugging a core dump, or entering code directly through the switches on the system console.
Meanwhile, this picture of an upright 1960's style upright tape deck, brings back a memory of IBM's Test Centre behind plate glass windows on downtown Rissik Street, with eight such tape drives arrayed majestically around the system unit, where one had to book time to be the single, sole user of the system. Working on a customer benchmark, I set up a large sort (a major feature of all sequential, batch-based systems in those days), to use all 8 tape drives, one input, one output and six work files, and then retired to watch the entertainment with colleagues and other sundry onlookers from across the street, as the reels spun endlessly back and forth in some weird choreography. The Wired caption says:
Today, the System/360 more closely resembles something out of an early Star Trek episode than one of the most important business innovations of all time.
Star trek? Much better than that, in my opinion!
IBM's rather tame tribute on their website is here, while CNET's anniversary review focusses more on the mainframe market of today than on nostalgia.
The Computer History Museum is worth a visit, and their System/360 page is here.
The classic IBM Systems Journal article on System/360 Architecture, by Gene Amdahl (yep, he was one of the fathers of System/360), Fred Brooks and G A Blaauw.
