Big, Beautiful Boxes From Computer History

Slatterz writes "We might sometimes complain about the limitations of today's technology, but there's nothing like seeing photos of a 27Kg hard drive with a capacity of 5MB to put things into perspective. PC Authority has toured the Computer History Museum in California, and has posted these fascinating photos, including monster 27Kg and 60Kg drives, and a SAGE air-defense system. Each SAGE housed an A/N FSQ-7 computer, which had around 60,000 vacuum tubes. IBM constructed the hardware, and each computer occupied a huge amount of space. From its completion in 1954 it analyzed radar data in real-time, to provide a complete picture of US Airspace during the cold war. Other interesting photos and trivia include some giant early IBM disc platters, and pics of a curvaceous Cray-1 supercomputer, built in 1972. It was the fastest machine in the world until 1977 and an icon for decades. It cost a mere $6 million, and could perform at 160MFLOPS — which your phone can now comfortably manage."

Nice photos...

Although these photos don't include the functional replica of Babbage's Difference Engine #2 that's currently at the museum, and leaves in a few months. I was just at the museum two weeks ago. It was pretty interesting. There's also an exhibit about the history of chess computation. Apart from those two things though, most of the museum is a big room full of old computers. I wish there were more to see there, but what is there is pretty interesting. I recommend going before the Babbage Engine leaves in a few months if one gets a chance.

What kind of dumbass captions are these?

" The Enigma machine was used during world War Two - it gives more than a trillion possible combinations for a single number, making it impossible to decrypt letters encoded with the Enigma. The big silver piece next to it is a part of the Colossus - a British code-breaking computer."

The writer obviously doesn't know what he's talking about and didn't bother to read any text associated with that display, if he thinks Enigma was unbreakable. Especially since the parts of Colossus were specifically for breaking Enigma. Further, "more than a trillion" is a ludicrously imprecise figure, why couldn't he at least look up a more accurate figure (10^23 according to Wikipedia)?

A lot of work was done on breaking Enigma BEFORE WWII - by the Polish.

The wheel wirings had been discovered (whether by fair means or foul - ie capturing the actual wheels - I can't remember). Enigma was basically hacked^Wcracked by using the fact that a lot of the German messages had key, crib phrases at the start or end of the messages, and that no letter could encrypt to itself. It was Bombes which were the set the task of finding the starting position of the wheels given a possible crib match.

The German Navy used an enhanced enigma machine which used 4 instead of the normal 3 rotating wheels and so was harder to crack. That was helped by the capture of the settings books (about 2 years before the US entered the war).

It was the Lorentz cypher, as used by Hitler and the high command, was the cypher that was decrypted with the aid of the Colossi. A Lorentz machine was bult at Bletchely Park by modifying a British cypher machine.

Bletchley Park is well worth a visit to see the reconstructed Colossus and the computing museum - it was most odd to see the computers I used as a wee lad in the museum.

It's sad that none of it works

The sad thing about the Computer Museum is that almost nothing there works. The Difference Engine replica is about it, and that's entirely mechanical. Some people tried to restore an IBM 1620 back in 1999, but they never got it working.

It's almost the last computer museum, too. The ones in Boston, San Diego, and Germany went bust. There's one still open in Bozeman, Montana. There are a few others which are just stuff in storage. That's about it.

The history of this field disappears very fast.

You would think they could have gotten this right.

The caption on one of the photos (Image 30) reads:

The highlight and centrepiece of the Museum - The Babbage Engine. It's a replica, made in the British Museum using the original as a template.

This is not a replica of an original. The machine in the British museum was built by a team using Babbage's note. No original was ever built, as Babbage could not get funding for the project. The machine at the Computer History Museum (as pictured) is the second built by the same British Museum team who built the first.

If you want to see it, it will be at the CHM until December 2010, at which time it will be moved to the home of Nathan Myhrvold, the person who paid for its construction.

The article is about a time when CPU cycles were more expensive than programmer time and text data took a lot of space.

That's about when I started -- punch cards and all. Maybe two or three turnarounds a day. Before sending a program in to run through the assembler, we were expected to sit there and "play computer", going through all the operations of all paths through the programs before "wasting time" on the big iron.

Mind you, this was in the afternoon. The mornings were spent cutting down redwood trees, tapping rubber trees and mining graphite, copper and zinc so we could fabricate our own pencils for the afternoon's work. The real hotshots didn't make programming mistakes, so they could skip tapping the rubber trees for use in making pencil erasers.
