50 years ago today, IBM announced the 1401 Data Processing System. Originally designed as a spooling system for the larger machines, the 1401 became very popular as a mainframe in its own right, eventually being called 'The Model T of Computers'. By the end of 1961, the number of 1401s installed in the United States alone had reached 2,000 - representing about one fourth of all computers installed by all manufacturers at that time. 15- 20,000 were eventually built. The Computer History Museum in Mountain View is having a 50th anniversary celebration on November 10th. Here's what $125,600 (or $2500/month rent) would get you: [more inside]

The History of Computing Project is a collaborative effort to record and publish the history of the computer and its roots. The site includes a chronological timeline, biographies of computing pioneers, a look at computing hardware through the years, as well as software and games. [more inside]

"In 1964, a computer - the IBM 1401 Data Processing System - arrived in Iceland, one of the very first computers to be imported into the country… The chief maintenance engineer for this machine was Jóhann Gunnarsson, my father. A keen musician, he learned of an obscure method of making music on this computer - a purpose for which this business machine was not at all designed… When the IBM 1401 was taken out of service in 1971, it wasn't simply thrown away like an old refrigerator, but was given a little farewell ceremony, almost a funeral, when its melodies were played for one last time. This "performance" was documented on tape along with recordings of the sound of the machine in operation." The whole story with samples, pictures and video at Jóhann Jóhannsson's site. [via]

Mainframe - The Art of the Sale. Lesson 1, Lesson 2, Lesson 3. Brought to you by 360comedy. It helps to know what a mainframe is, but is not absolutely essential. Enjoy! (Post contains YouTube links)

Hercules! Not the shiny muscle man from the past, but a handy emulator for IBM S/360, S/370, S/390, and z/Arch mainframes. Unfortunately, because of IBM's bullheadedness, you can only run operating systems released when the world was young, unless, for whatever reason, you decide to run something released after the Reagan Administration. You, too, can learn how easy we young whippersnappers have it now, but beware: to effectively use most of these systems, you will need to descend into Hell.

Electronic music buffs cite Radiohead's Kid A as their best work. How many know that Idioteque, arguably the stand-out track owes a debt to Paul Lansky, sampling as it does Lansky's Mild Und Leise [mp3 file], a track composed in 1973 on an IBM 360/91 mainframe. I didn't. Should you find your interest piqued, you might want to read an interview with Lansky. If that was then, this is now: The excellent music video to Zeal [Quicktime] by Plaid, which, although a very different beast, is an excellent indicator of how far electronic music has come. [Probably NSFW].

Multics, Requiescat in Pace. Wow. What does one say.

I know you're all probably missing that old mini-mainframe you used to program on as a kid, right? Ok, maybe that's just me... But darn it, I can do it again using this PDP-8/E simulator for the Mac. You can even write your own simulated DEC I/O devices like paper tape readers via a plug-in API. And for the techno-frankenstein in me, it'll run using SheepShaver on my BeBox too.
