Granted, it displays only 8 lines of text and has just 28 kilobytes of memory, but it's a classic, the first truly popular portable in the U.S. At PC World we have a teardown that'll show you the guts of this featherweight champ." And, like many of the best things in life, it's powered by AA batteries (as is the Apple eMate).

      Actually, this comment really shows how no one bothers to do a little more research than just reading titles.

      For instance... did you know...

      These computers, as well as the TRS-80 CoCos and the Model I, III, and IV units... the units that saved programs to cassette, have greater wireless capabilities than our current hardware. All it takes is to plug in the input and output that are supposed to go to the cassette recorder, and patch it into a HAM radio. It's already being done. People are sending programs and information half-way around the world, without wires and without the assistance of satellites.

      A friend was cleaning out his garage once and had one of these in a box. He gave it to me. I like tinkering with antique computers on occasion. (I still have my C64 programmers handbook that has the fold-out motherboard schematic in the back.)

      A few years later, I velcroed it to a pull-out rack shelf and hooked a null modem cable to it to monitor the console output of a SSL Screen Sound setup (proprietary pro-audio digital mixer/editor in the days before Pro-tools). It couldn't quite keep up with the 9600 baud stream if there was a lot of data streaming fast like during bootup. It did the trick, however, when you just needed to go in and check some of the statuses while the system was running. I think I mostly used it to go in and low-level format the hard drives on occasion.

      It was useful for a while, and that must have been somewhere in the mid-90s that I used it.

      What's interesting to me is the tension this sets up with operating systems like Vista which are moving in the opposite direction.

      Just when the ultimate in MS bloatware comes out, suddenly a new (again) market appears for ultra-portable general-purpose PCs that can't run Vista.

      So we have WinXP on the OLPC XO-1 and Asus EEE PC, etc., because Vista's too big and WinCE is too small. XP or linux+xfce are juuust right.

    What wouldn't you give for a laptop that starts instantly, weighs 3 pounds and gets 20 hours of battery life?

    I'd give a lot for that, but this wasn't it. This is more accurately described as a PDA that fits on your lap. What it did, it did well (for the time), but it was very limited. And modern PDAs get a lot more than 20 hours of battery life.

    In other words, if you want a modern Model 100, get a PDA with one of those fold-up keyboards and go to town. Instant-on, long battery life, and destroys the Model 100 in usefulness.

  • I still use a trusty old HP 200LX, which sports a graphics shell, MS-DOS, 2MB RAM which serves part as disk, and it too runs on AA batteries.
  • I have one of these as part of my "classic computer" collection, and it was the best eBay find I ever got. For something like a hundred bucks I got a Model 100 in near mint condition, with a faux-leather carrying case that was in such good condition it still had the cardboard insert from the packaging in it, a boxed cassette recorder, some software on cassette (remember the good old days when software came with a leather-bound binder containing printed instructions?), all the hardware and software manuals,

    ... the Model 100 is kinda the definition of the perfect portable:

    • Insane battery life on bog-standard AA batteries you can buy in any airport gift shop
    • Full size keyboard for easy typing
    • Screen you can read in sunlight
    • Case tough enough to take a serious beating without a flinch

    Sure, it doesn't have the bells and whistles the kids are into like "color" or "graphics", but in a portable for writers none of that is really important -- which is why many journalists held on to their Model 100s long after they became ludicrously obsolete.

    With the demise of products like the Psion Series 5 [wikipedia.org] (another writer's portable), the niche that the Model 100 pioneered has basically been abandoned; the only thing close to it today is the EEE PC, which would be an ideal spiritual successor to the hardy 100 if the keyboard wasn't so danged small...

  • This reminds me of the Psion Series 3a [wikipedia.org] palmtop, which is almost 15 years old now.

    It had a great usable keyboard for its size (similar to a glasses case) and a big clear greyscale 480x160 screen.
    In terms of runtime, it would run for around 20 hours on a pair of AA's, with negliable standby power, ct1620 button-cell memory backup and instant-on giving literaly weeks of reliable operation between battery changes.

    My friend had a Model 100 and I was so jealous. That thing rocked! But I still have my TRS-80 PC-2 pocket computer. It's so easy to use. It's better than a calculator. You can type out entire formulas then if you make a mistake you can hit the back button and see the whole formula and fix whatever you did wrong. I use it every year come tax time. For such a small display you can address every pixel if you want to draw something or make a simple game and it has a speaker you can play music on. I also have the cassette/printer interface. The printer isn't a dot matrix but pen plotter. That was cool to watch it print reports or draw graphs. The paper goes up and down and the pens go side to side. That memory on it lasts for weeks on 4 AA batteries. Sometimes simple is better.
  • Durable as all hell, power lasts a long time (and spare batteries easy to carry), and a good old fashioned serial interface.

    We still use them to interface with SCADA gear out in the field. You're not going to want to haul a regular laptop into some of those areas.

    And yes, I've been trying to pilfer one ever since I discovered that they were still in use :)
  • My horse veterinarian used to use one of those. She had a PC running UNIX back at her office, and used the portable to connect to it from her truck.

Used it all through High School for taking notes in class (can't write fast enough), and again through college. Just plug in the serial cable and upload to PC at the end of the day. Although by college I'd upgraded it to 32k via the wonderful Club100 site that still sells parts/addons/programs for it (http://www.club100.org).

    It also gave me my start in programming via hand-keying games from a book into it, and learning
  • I have a Model 100 and the thinner Model 102. I used the 100 in college in the late 80's to take notes in class, and even wrote an alarm clock program that woke me up in the mornings! I did a little hack so that it would charge ni-cads from the ac adaptor (not a standard feature). I have the floppy drive, bar code reader, modem cups, etc... It had a very well integrated operating system. one of the better things microsoft has done IMHO.

  • I volunteer as a race official at some bike and running races. One of the guys who does the chip timing for some of these races still uses them as data loggers. He has a whole trunk full of spares he picks up at garage sales.

    Nowadays, it kinda makes me miss my Psion Series 5.

    I bought one of these in 1980 and it still works perfectly. What made it so amazing was that it had the BASIC programming language included with the ablity to create sound, a modem and other goodies. The OS for this device was reputed to have been the last piece of software that Bill Gates himself wrote. The user's manual was incredibly badly written--with page references to non-existent sections, etc. The manual was also reputed to be Bill's first book.

    on one of these that my uncle gave me. Pretty much changed my life.

    What this article really failed to mention was the software side. You could program anything on the computer in BASIC and the LCD screen made it easy to create and position graphics (no need to worry about resolution - each pixel is always in exactly the same place and precisely the same number characters will always fit on the screen.) Made for years of writing games and applications on that thing. This is really something the "laptops for kids" people should be thinking about.

    Simon Travaglia originally scored a TRS-80 out of a bin at the university he worked for at the time, and he wrote out a few articles of the Striped Irregular Bucket. Within that bloody machine came the character of the BOFH, and the rest...is something.

      The Z88 LCD is half the height but higher resolution.

      Nice machine. One drawback versus the M100 is that it has a capactitor instead of a NiCd for maintaining the RAM disk. It seems like it wouldn't matter but in practice it is a huge issue.
