Trying The First Portable Computer: The Osborne 1

  • The Osborne model 1 is described as the first commercially successful portable computer. Weighing in at nearly 25lbs and sporting a 5" screen, it wasn't really all that portable or convenient, but it did inspire many successive portables, luggables, and laptops.
    I recently got ahold of one at an estate auction, and it's in great shape! I did have to replace the vintage power supply capacitors, since those almost always fail on these old computers. I also replaced a faulty floppy drive with a Gotek disk emulator, and made some other small adjustments.
    And no, as far as I know, it can't play Doom :-( In fact it does almost nothing modern at all, and is kind of a giant pain to make compatible with anything modern! I did manage to get a few programs onto it, and we might re-visit this in the future. For now it's mostly a fun novelty and a neat way to look at vintage tech.
    Some of the resources I used when working on this computer include:
    GoTek Floppy Emulator: www.ebay.com/i...
    3-D printed adapter for the GoTek: www.thingivers...
    Kermit disk image (bottom of the page): blog.nroach44....
    Richard Loxley's blog about Osborne file transfers: www.richardlox...
    I'd also like to thank Iso-Tip for sending me their cordless soldering iron. It made the capacitor replacement super easy! You can find them at iso-tip.com/ (Use code SMART24 for 15% off!)

    A friend of mine was the technical illustrator for Osborne, making all the illustrations in the repair manuals. He was at a computer show and remembered Adam Osborne telling people who were terribly excited about the Osborne 1 that they'll like the Osborne 2 even better! People said, "Oh? there's a 2 coming?", and decided to wait to buy the coming model 2. Few people bought the model 1 so they went bankrupt. Loose lips sink ships, or shrink spliffs, I can never keep that straight.

I had a couple expansions in it, don't remember all of it but I did have the screen expansion that put 80 characters on the screen to eliminate the scrolling. I'm pretty jealous he was able to just download the space invades game, I had to type in all the code from the magazine.

    Gosh, this brought back memories. The caps actually would dry out and buzz before they smoked. Ultimately I wound up throwing away four of my Osbornes since there was nowhere to get rid of them. It was the first computer to flag my spelling errors. It would not fix them or offer you any options it would just flag words it did not recognize. It had word-wrap so your text never went off the screen like you are saying. I remember teaching myself WordStar one summer.
    This is a good time to explain to people why the hard drive is called the 'C' drive. Since the 'A' drive is one on the left with the one on the right being the 'B' drive and when hard drives came out they became the 'C' drive! It's been that way ever since.
    I still miss a lot of the CPM commands since there were global and filtered commands that are just not available in Windows.
    I had about 3-4 of those soldering irons back in the 80s too and they sucked so I wound up throwing them away too. I went to the gas soldering irons.

The good old Z80, unfortunately, its production is being discontinued. I think people were stronger back then because 11 kilograms is not a lightweight. A very nice project, Adam Osborne built something exciting there. Those were devices I could look at at trade fairs.

    You are absolutely correct about the three caps (RIFA'S) but looking at C18 the round electrolytic that is just next to the heat sink that is in the center of the power supply board TS 07:27 you finger is right over the top of it.
    It looks like it has gotten hot, Judging from how much of the sleeve has shrunk down. If you look at the other caps their sleeve is still over the top of the can. This is a dead give away that it has gotten hot. another failure is the top will be bulged up. also any signs of fluid leaking out of the top of the creases of the can and the bottom of the cap.

    The zig-zag lines on the CRT are due to the beam re-trace. That is, the electron beam returning to the top after scanning down to the bottom of the screen. Normally, the beam should be blanked during this time so that the lines do not show up. Your monitor must have a fault either in the retrace blanking circuit or in the overall brightness. Could be more capacitor troubles, or it could be a resistor in a high-voltage area that has changed in value.

    Galvin was the first, but they were sued by Motorola and forced to change their name. Motorola was called Galvin Manufacturing before they developed their car radios. I saw a Galvin in a store, but it was being shipped back to the OEM to be re-labled and change the BIOS chip to display the new name.

      @@saveitforparts There are several important differences in it and any C64. First, its 60Hz clock signal comes from a crystal oscillator module. with an internal divider to provide a 60Hz TTL clock. Second, the keyboard cable uses a special 23 pin connector that is very difficult to find. One of the ROMs is also different, in that you can load the first program on a floppy with just two keys. I believe it also used a slightly different VIC chip because the video was much better than most C64.
      I used one of mine 30 years ago to emulate all the patterns on a Tektronix master sync & test generator when I was building Ch 58 in Destin Florida. All they had was a building and a transmitter so I had to bring my own test equipment.

    Cut power on for no more than 5 sec. Let sit for 10 to 12 hours or more; repeat ON/OFF cycle at least one more time; maybe leaving on for 10-15 sec if no caps blowing or getting hot. After two or three days, the caps should be reformed and you should be good to go. Good luck!

    Display lines are called retrace lines, thats the high voltage electrolitic capacitors (probably 600v) in the high voltage power supply, you'll find them close to the flyback transformer.
    While in there look at the sawrooth waveform (now you can use that oscilloscope) distirtion there will also cause retrace.

    I used one of those when I was in the 7th grade. Back in the day, there was a computer store called Computerland that used to let students come hang out at the store and use computers....

    "I did have to replace the vintage power supply capacitors, since those almost always fail on these old computers." - Always replace them, regardless, before power up. If you haven't operated the device in years, change them. It's not worth the bigger things that usually go with psus when they die.
    Like for example, i had a TV, NOS in the box, never opened. My dad needed it, so i helped him set it up. Just before i'd put it in the plug i said "you know, magic smoke will come out" - and so it did.

    I had a vendor give us a lugable as well call it a bit like that from the 90s with it had protocol card like frame relay , sdh stm ATM, e1, protocol decoders, test and decodes realtime worth about half a mill , one rep said one day car got broken into they tried running off with one , but dropped it as I weigh about 20 kilos

    i was around in this era..strangely one complaint from users was the ports being on the front..yes it makes it easier to plug things in but if you have a lot of cables plugged in they tended to lay across the keyboard..which was irritating to users...

    These things being portable are roughly equivalent to the early _"brick phone"_ cellular telephones.

    For the serial port, you need a dongle in the middle with LEDs on it. You need to make sure that you have Rx and Tx swapped, and you need to make sure they're both using the same form of flow control. Probably best to use xon/xoff (software) flow control. After that, you need to play with parity, data, and stop bit sizes and port speed. Start with N,8,1, 300, and go from there. No way that port is faster than 2400.

      @@saveitforparts cool. For DB-25, 2 is tx, 3 is rx, 7 is common. 2,3,5 for a DE-9. You need a null modem cable or physically swap lines so that rx off one side goes to tx on the other, and visa versa. As for hardware flow control, good luck. I hardly ever used it, and couldn't remember them. I think maybe rts goes with cts, and cd is pin 1?

    • @saveitforparts
      @saveitforparts  Месяц назад

      I read somewhere that you don't want null modem for this, or maybe that was another computer I was working on. I do have a few of those as well, plus Ye Olde Laplink cable.

    • @paulheitkemper1559
      @paulheitkemper1559 Месяц назад

      @@saveitforparts if it's dcs equipment, it's already swapped inside. That's why you need the LED dongle. Tx will light the LED for that side. You want to see Tx and Rx lit, else both sides are connecting Tx on the same pin, which obviously won't work.
      I suppose you could use a meter, but it's helpful to just leave it inline during the whole process. Plus, you can see the flow control lights go off and on based on settings during the comms, and that's kinda fun. Those old ports were so slow, sometimes it feels almost like you could decode the bytes manually.
      I've heard a null modem cable called a laplink cable. I think they're the same thing.
      Personally, I always liked the null modem cable that has a Y with 9 and 25 pin connectors on each end. You could talk on the 9, and connect the dongle on the 25
