Thirty Years of Clamshell Computing

harrymcc writes "2012 marks the thirtieth anniversary of the Grid Compass 1101, the first portable computer with a briefcase-like case with a keyboard on one side of the interior, a flat screen on the other, and a hinge in the middle--the 'clamshell' design that eventually became standard for all portable PCs. It's proven to be a remarkably useful and durable design, and only with the advent of the iPad has it faced serious competition."

      You are right that the TRS-80 was a popular system in the space it was in. I had a Model I and a Model IV, so I know I enjoyed the Tandy brand. Don't confuse market leadership with having a mature market.

      If you went to an office, you didn't see a Tandy (or other computer) at every workstation and most families didn't have a computer at home. By the time computers really started to hit the mainstream, Tandy had flamed out and became a distant memory. I even had a 1000 Series, but it would be my last... too proprietary, too locked in and worst of all, it didn't play Doom :)

      Competition doesn't just mean that alternatives exist. They also have to be popular enough to matter.

      "Popular" is overrated. Just because you're popular doesn't mean you matter. It doesn't mean "good." Windows and Apple are popular. So were Hitler and Stalin.

  3. Miniturization of electronics by MyLongNickName · · Score: 5, Interesting

    As electronics become smaller, the only pieces that must remain large are the input and output devices, so the clamshell makes the best use of space. The iPad's input device isn't meant for serious input... a keystroke here or a mouse click there. Typing a real paragraph is a pain the fingers.

    Now what I am really looking forward to is when these computers can output directly to my retina :)

  6. Also first coveted computer by fermion · · Score: 4, Interesting
    Everyone who knew about a Grid wanted on. It was the first piece of computer industrial design I knew about. OTH it really wasn't a clamshell. it was a pop up screen, like the tandy 200, released two years later. I would say the Tandy 200 is the first useful affordable laptop computer. Both were integrated systems with custom OS. It is interesting to note that we are returning to metal enclosures for high end computers, or those that want to look like it.

    Unlike the Tandy, the grid computer only ran on line current. Compared to other portable computers the innovation in this machine was the flat display and internal expandability and storage. The expense of the screen was significant. Note that first Apple Mac was also a portable computer, but used a CRT.

    In any case most of the computers through the 80's were not laptops, and we did not get reliable clamshells until 1990's.

  7. Sorry, but iPad is *not* a challenger. by Anonymous Coward · · Score: 3, Insightful

    Anyone who does anything productive an iPad ends up buying a case and a bluetooth keyboard, ending up with exactly the same overall use case as a clamshell laptop. The only advantage with the iPad is that the keyboard is optional, but for those of us who do a lot of work that "optional" part is a hassle and thus I always end up just using my laptop anyway. Anyone who claims they can be productive for long periods of typing with the terrible iPad on-screen keyboard is probably lying.

  9. Best use of space in clamshell? NOT by Alwin+Henseler · · Score: 5, Interesting

    (..) so the clamshell makes the best use of space.

    Considering today's power/heat constraints, I find the usual "CPU/GPU under keyboard" configuration illogical. Why not a CPU / GPU / RAM board behind the screen, with a large/thin (passive, if possible) cooling plate at the rear? Or draw air in near the hinges, let air out near the top of the screen (again, passive if possible). Those 2 cooling methods wouldn't bite each other... Then just battery, keyboard, hard disk and peripherals like DVD drive (if fitted) under the keyboard. A few serial connections like USB / SATA + power between the two halves. Likely would leave more space such that a larger battery is possible.

    Much better than packing heat-producing CPU/GPU right next to a heat-sensitive battery (+ a tiny blower to pull that heat out).

      Weight distribution. If the lid is heavier than the base, it's too easy to have the laptop do a backwards flip. Besides, it would add thickness to the machine (but allow for a bigger battery)

    The very first time I saw an on-screen keyboard, I knew it would never be more than a low-throughput device. I rooted for other screen-based input solutions, but Apple never let them be used as the default interface. Some of them actually worked quite well: I was able to get to 50wpm using the IBM SHARK input method with an afternoon's practice.

    no I have a dec laptop with a trackball in the now normal position, Its date of manufacture is 1990 which is the same year as the original Macintosh portable started coming with a backlight, and a year before the first powerbook. The original portable in 89-90 gave you a reflective screen (think gameboy) a full sized keyboard, a full sized trackball on the right of the keyboard, and ran off of lead acid batteries. It was a old clunky luggable about 6 years too late.

    The first powerbook came out in 91 and it came with the trackball built in, which makes since as you HAVE to have a mouse with a mac. My DEC clips onto the front with pogo pins that make the contact as an option. So while the powerbook was the first one with a built in pointing device, PC makers have been putting the trackball under the keyboard for years as an option
