Re-Opened Computer History Museum Explored 181

gosand writes "An article over at OSNews gives a nice overview of the recently re-opened Computer History Museum in Mountain View, CA. There are some good pictures in the article, and also at the Museum's website. They have a lot of very interesting computers, including an Apple I (signed by Woz), an Enigma machine, and Crays 1, 2, and 3 (yes, there was a 3!)

        Well, that's liberally paraphrased, but the thing to understand is the person who said that was *right*.

        He was making a practical observation about the market, and the market would have been saturated at just a handful of the computers of the day.

        A person making a business plan for the next fiscal year doesn't need to worry about a technological revolution that may take place over the next decade or half century.

        The collection does include international representative machines, including a great deal from the UK. Only about 10% of our collection is actually on display, and even less is currently available on the web. If you want to help us change that, come volunteer.

      No Compaq in the list.

      I have one of the original Compaq "luggable" computers (serial #1555) when they were still limited to two 5-1/4" floppy drives.

      I subsequently upgraded it to an XT-clone, with a giant (at the time) 10 megabyte drive. It was one of the first 3-1/2" hard drives, shock-mounted (with big rubber "feet") within a 5-1/4" enclosure.

      I still have it, complete with the nylon carrying case. I dig it out once in a while and boot up DOS 3.3, just to boggle the mind of people who have never seen one.

      I can now build a complete near-top-of-the-line computer for about 15% of what I paid for that thing, and that's not even accounting for inflation since the early 80's.

      I've been wondering if Intel or AMD will release a 4.77 GHz processor, to commemorate how far we have progressed since the original 4.77 MHz 8088 processor in the first IBM PC.

        While there are some machines that will get this treatment, there are too many that are too costly to run or repair to ever try to plug in again.

        Certainly most of the PC era systems would still boot, but in an attempt to preserve them, we aren't going to try.

        There are a few places where more contemporary machines can be seen in their fully pixelated splendor (running) that you can visit.. Get it while the getting is good.. it onl

  • Somewhere, I have a TRS-80 and an Osborne that has its original modem and CP/M disks. I think I have Wordstar for it too.

    "The Computer History Museum in Mountain View, CA became the first in the world to run an http server on a vintage Altair 8800. The exhibit was promptly destroyed when millions of crazed fanatics of the website "slashdot" tried to access the Altair at the same moment."

    I visited this place a few years ago when it was a bit harder to get into and it was fantastic! Back then you had to call ahead and get an escort through the guarded gate onto the base. The museum was a few ancient warehouses in the shadow of this monstrous dirigile hanger [nasa.gov] which is also an amazing sight.

    I forget his name, but the person who ran the museum was very cool and took an hour just guiding me and a friend through the museum chatting about all the computers they had. Back then everything was in a huge dark warehouse on big dusty shelves. It felt like walking into the government warehouse at the end of the Raiders of the Lost Arc. Every time you turned a corner you were facing a lost treasure.

    Crazy old LISP OS machines in wooden cabinets. One of the original Internet routers the size of a refrigerator with a hand drawn network map of the Internet from 1979 still taped to the side. An amazing old Cray that looked like an art deco couch from the movie 2001. Computers that look like telephone switches from 1901. The kitchen computer! Oh my GOD they actually built this thing! [old-computers.com] See it and believe it. :-)

  • ...is an extinct species known as the "Programmerus Americanus"
  • i heard a rumor that they have one or more CMs. i actually know how to maintain them, does anyone know if they are looking to restore one? it would be fun.
  • Classic computers are really starting to be a collector's market. I remember just a few years ago you could pick up all the old 8-bit home machines you could ever want at flea markets and Salvation Army stores for $5-$10. Now it seems they've all been snatched up for sale on ebay for $50-$100, or more.

  • I wont be impressed until they have a working difference engine [ed-thelen.org] like the British Science museum.

    As one of the people who helped restore the Enigma machine at the History Center, I can attest to the fact that it is genuine. A few years ago, the donated Enigma machine was not in working order. It took a several work sessions to get it operational (cleaning, wire repair, replacement bulbs (of the same type and era), switch repair, etc...) The machine lacked 2 of the 5 rotor types, so another member did a lot of hard leg work to get a loan of some authentic rotors from a TLA.

    The Enigma is a bit cranky. The mechanical contact switches in the keyboard need to be cleaned more often and one might guess. The Enigma is not very ergonomic either ... :-)

    We used that Enigma machine to encrypt a real message that was known to have been broken by the folks at Bletchley Park. Some 60 years ago, their code cracking machine took ~2h 45m to search about 1/2 the key space (during which several false positives turned up) before the real key was found. Turing's algorithm, ported to a stock Cray 1, took 30 seconds to find the same key.

    The Cray 1, designed in the mid 70's, was only 330 times faster than the special purpose Bletchley Park code cracking complex. That 1940's technology used at Bletchley Park was truly amazing for its time.

    p.s. Not only does the Computer History museum have a Cray 1, 2 and 3; it has one of every major model that Cray designed going way back to his early CDC days and his special Navy machine.

  • until recently, I had a working Gould 32/67 (circa 1982) in my garage.

    It was only the size of a fridge, but weighed around 900 lbs. Too bad that my wife insisted that I get rid of it. She didn't see the value in a huge, energy gulping, heat pumping, two MIP machine :)

    I wonder if the museum would have been interested in such a beast.

    Wasn't this a super-fancy SGI building [computerhistory.org] not long ago? How the mighty have fallen.
  • I doubt they have one of these, as it was only sold in the UK in 1982-83 (it was heavily based on a Tandy TRS-80). Mine still works.

    Brief techie details: the Dragon and TRS-80 had a Motorola 6809E processor running at a couple of MHz, which was a hybrid 8/16 bit affair (for some operations such as MUL, the result was a 16-bit number which was placed in the combined A and B accumulators). It had X and Y general purpose registers, and S and U stacks which (at a pinch) you could use as extra registers. The
