Palm M100 "Kaizo" Hack: 8 Megs On the Cheap 99

Posted by timothy from the small-hands dept.
For those who must, absolutely and without fail, take apart anything electronic which crosses the threshold of their homes, Toolsmith writes, "Here's an interesting site explaining how to upgrade your Palm m100 to 8MB of memory. "Kaizo" is Japanese for "Upgrade". They show pictures of an m100 being upgraded from 2MB to 8MB. Here's the link. Has anyone tried this one yet?"

    "Must take apart anything electronic"... That's so true. I just bought a DVD player, and for some reason a disk got stuck in the tray. Now, the place I bought it is just a few blocks from my apartment, so I could easily have taken it back for service, but instead I just whipped out a screwdriver and started opening it up.

    I don't know if opening a DVD player will void the warranty, but I honestly didn't care that much. And it wasn't so much the disk or the player that I was concerned about; I was just suddenly filled with excitement that I had an excuse to see the inside of my new toy. It was at this point that I realized Wow, I bet most people wouldn't be doing this.

    Just thought I'd share... =)

    This looked fascinating to me until I realised that you need to rework surface mounted components!

    I don't know how many people who read /. have tried this, but I have a few years ago. It is possibly one of the most incredibly difficult things you can attempt! I could move that little resistor they have marked, but to succesfully remove an entire DRAM chip and resolder a new one would require some extraordinary skill!

    Even when I was at my most practised and my hands seemed rock steady to me I would NEVER have attempted this!

    even now i could remove the chip, but to put in place a new one would be unthinkable

    Please no-one try this unless you are completely sure you can pull it off, I have visions of hundreds of wrecked palms from people try to do this.

    If you DO want to try it still .. good luck :)
    but don't come crying if your Palm gets amnesia ;)

    Kaizo doesn't mean "upgrade"; it means "alteration" or "modification".

    BTW, if you go here [fureai.or.jp] you can read the original Japanese (and if you can't read Japanese, you can look at the pictures of the place where they did the modification - a little bar in Akihabara). The hack is more impressive when you realize they did it while getting drunk ;)

  • There are special irons we used to work SMT parts, but it was more for discrete capacitors and resistors and such, don't know what is recommended for working the multipin devices like the SDRAM in this case.

    Beautiful hack though!
  • It's not too difficult if you have the right (i.e. expensive :) tools... I took a class on surface mount soldering at the local community college (for no particular reason), and to remove surface mount chips, we used a large rectangular iron tip that would heat all the pins at once. Let it heat for a while so all the solder melts, and give it a little twist, and it comes right off.

    For those of us with lesser means, if you don't care about saving the original chip, you could probably use some small diagonal cutters to clip all the pins, then desolder the pins individually. If you do want to try to keep the original chip, use desoldering wick on the pins and gently lift them up. (Then you'll have to try to bend 'em all back in line if you want to use the chip elsewhere... if I were doing this, I wouldn't worry about keeping the old chip... that's way too much work :)

    As for the resoldering part, that's actually not that hard... take a surface mount soldering class to find out how it's done ;)

Too many people, IMO, are delving into stuff they don't really understand, and then bleating when they wind up with broken stuff.

    How do you do?
    Now you gonna die!
  • The key problem is most likely not only the mechanical one of soldering in the new chip but also that you have to be ultra careful not to zap the chips by electrostatic charges. So you need antistatic wrist straps and a place to attach them.

    I seriously doubt they did it in the bar in Akihabara which they mention on their Japanese page. This area of Tokyo is one of the most lively places you can imagine (only Shibuya or one of the major subways stations are similar).

    Besides that, you really need a very steady hand to solder pins that have a 1.27mm (i.e. 1/20") grid, hence roughly 0.5mm distance between the pins.

    But with the right tools it's ok. I once had to build a pre-series demo model using SMD chips and it worked fine (but took forever).

  • Well, I actually taught myself how to do this :)

    oh, and clipping all the pins IS a cheating method, but hey, it is how i would have done it, then your can remove the old solder and remains of legs at you leisure.

    And yes, whilst soldering a new chip in is technically quite simple (hint: stick the chip down to hold it in place, but don't use massively strong glue in case you want to reposition it :). that is a fantastically huge number of pins and I would never be able to keep my hand steady enough to do it without making a mess of the whole thing :(

    all through this, you have to make sure you only apply as much heat as you need, because too much heat will make all the tracks on the board curl and peel off. I watched this happen once, it was a horrible sinking feeling in the pit of my stomach.... AND the damn solder still didn't melt

    ok, time to stop waffling and go back to working :)

  • Yeah. Then there's the people who post to linux-kernel saying things like, "I've been getting these strange oopses - it looks like something's buggy in the memory management", and go on to give a system report that begins "CPU: Dual 300MHz Celerons @ 450MHz..."

  • Why do you "seriously doubt" that they did it in Akihabara? It even has photos of the place where they did it. And Akihabara is nowhere as busy as Shibuya, Shinjuku or any of the major business areas in Tokyo. Added to that is the fact that they did it in the evening (after 7:30), when Akihabara is a lot quieter than it is during the day.

    They even thank the owner of the bar for letting them use electricity and bring a soldering iron into the bar ;)


  • I get told that roughly once every five posts I make, but I think a search time of less than a twentieth of a second is cooler than adding an extra 20 million sites ;)

    Well, there's a knack to it, and you need the right tools (Good Iron, solder wick, heatgun, good eyes ) and lots and lots of practice but replacing surface mount IC's ain't that hard.
    When we (as in the development section of my company) were smaller we used to do it fairly routinely for prototypes and I've done 208 pin QFP fit/replacements by hand with a pretty good (four out of five) degree of success first time round. Some of our full time line techs get way better success rates than that. They tend to heat the component with a heatgun lift the thing out whole (note: leave the pads on the PCB ;) then clean up the area with wick, put down the new device, anchor the corner points, drown the thing in flux and then just run across the device pins with the iron and solder, finally clean up any pin shorts with wick and job done. (It's pretty impressive to watch this happen at first)

    OTOH I'd agree that the average /. reader should never try any of this on anything as expensive/neat as a palm pilot...Well not your own anyways... ;>

  • I haven't done the palm upgrade (I don't have a palm pilot), but I did replace the 32k sram in my hp48g with 128k sram.

    The sram was surface mount... I just used solder braid to get it off the board.

    Soldering on the other chip was challenging, and even more so as I have shaky hands. I clipped tiny segments of solder off of the solder spool using an exacto blade... the pieces were maybe 0.5 mm to 1 mm long. The solder had a rosin core so the pieces were like donuts. I then stuck the pieces onto the leads of the sram and placed the sram on the solder pads on the board.

    With the small amount of solder in place, I didn't have to be tremendously steady with the soldering iron. I did manage to bridge a couple pins, but the exacto blade separated these as well.

    I suppose you could use solder paste, but I've personally never had much luck with the stuff.

    I wasn't too familiar with electro-static discharge at the time, so I didn't use a wrist strap. But this was in missouri, and if you have something like 40-50% humidity static usually isn't a problem.

    years later I am still using the same calculator.

    so anyway, surface mount isn't always that hard to manually work with.

  • I can't believe that got a +5 informative... and I can't believe I just complained about moderation... I guess there's a first for everything!

    This looked fascinating to me until I realised that you need to rework surface mounted components!

    Anything you want to hack these days you will do so by reworking SMT. It's a fact of life until we get to molecular circuitry, at which point I think the game will be over for most people. Hell I think with the BGA stuff now it pretty much is over for the hobbiest.

    It is possibly one of the most incredibly difficult things you can attempt! I could move that little resistor they have marked, but to succesfully remove an entire DRAM chip and resolder a new one would require some extraordinary skill!

    Actually reworking SMT is not all that hard. I used to assemble PCMCIA video cards (204 pin TQFP, some SOJ, a handful of 1206 resistors and capacitors, etc.) with nothing more than a pair of tweezers and a fine pitch soldering iron.

    Rework is slightly more difficult but the simple truth is that if you're going to throw away an IC, the best way to get it off the board is to take a razor blade and cut the pins off flush with the case and then remove the pins from the board. Much cleaner, and much less chance of damaging the board itself. If you've got to save the chip things get more difficult in a hurry but that's another story.

    even now i could remove the chip, but to put in place a new one would be unthinkable

    Placing a TQFP or other fine-pitch component is a piece of cake. You need that fine point iron, some solder flux and solder:

    • make sure the pads are clean (i.e. flat)
    • take your flux pen and put a fair amount of flux on the pads (just wipe it across a whole row at a time)
    • place the chip down and carefully line it up
    • tack down one corner of the chip. There should be enough solder to short 3-4 leads together
    • re-align the device (it should only need submillimeter realignment) and tack down the other corner
    • use the flux pen and wipe it across all the pins, a whole row at a time
    • Now this is the tricky part... you literally drag the soldering iron across one side of the chip.
    If you had enough of a solder blob and the iron angle is right and you've got enough flux, you will leave a perfect amount of solder on each pin and the solder job will be indistinguishable from a professionally mounted device. The speed at which you drag it is enough to heat up the pad and the pin sufficiently and the capilliary action of the solder "sucks" it under the pin and bonds it to the pad. I destroyed a few devices (bent the pins, you can never get them looking right again) with the wrong angle but once I got the hang of it down, I could do a 204 pin PQFP in about 6 minutes. I did up 150 prototypes that summer and not one had a failure in the solder work.

    This kind of stuff can be done, and quite easily... you just need to keep your most valuable resource (patience!) handy and keep your excitement in check.

  • Is it possible to do this same type of hack to a TI-83+ due to the fact they use the same type of proc (Dragonball Z80)?
    TI-8x uses a Zilog Z80 processor, no relation to the Motorola Dragonball processors used in Palms.

  • it was a 30 watt iron, which is pretty excessive for the job... a 15 watt would probably be safer.

    That's a common misconception that heat kills.

    In reality, too little heat is actually far more damging to the board. You end up causing the pads to lift up from the epoxy board by keeping the iron in there too long.

    Yes too much heat is damaging, but I've seen far more boards killed by people and their "cold" irons. Use a hot iron, get in, and get out.

    I used to sometimes carry around small MS-DOS executables on my HP48-Sx calculator. It had kermit, after all. Things like that marvel of utilites: Dirmagic, which was like 8K bytes.

    They didn't run on the calculator, but you could push them out the serial port to whatever computer you wanted.
  • Are any of you as obsessive as I am about getting each and every screw back in?

    Yeah, but I lose half of them half the time, and then spend a while frantically obsessing where they might have gone and gently shaking the unit to make sure there aren't any screws stuck inside... I need to buy one of those toolkits with the screw holder.

  • Can we expect a world epoxy shortage as Palm splatters it all over the pc board to prevent people from, um, reengineering their Palms?

    Oh, that's right, this isn't Netpliance. Sorry. Carry on....

  • In order to realize the possibilities of this, stop thinking of the Palm as an organizer. That's what it gets marketed as. Now start thinking of it in different terms, for example...a small terminal you can put anywhere in your house. Check email, sequence MP3s, view current news, weather, etc. It is essentially a small computer waiting to be put to good use.

    They work well as dumbterms too. With extra space in this thing, the next step could be a use for something like monitoring and recording performance data. I've been thinking about using the serial port to take readings and record flight data with my Palm on a model airplane.

    The price for the old palms is only $150 now. Where else can you get a copmuter with a display for that much?

  • It's not just the electronics, it's just about anything that can be taken apart!

    I think I started taking apart all of my X-mas toys when I was about 5 or 6 years old. I was 8 or 9 before I was able to start putting things back together again successfully, though.

    The worst is when you crack something open, and all of a sudden all of the parts don't fit inside anymore (like coil-wound springs :-)
  • Maria is edefinitely not normal.
  • My angle? Well, he's wrong ;)

    But no, really, it doesn't mean "upgrade". The word you'd use for a (memory) upgrade is zosetsu, or more generally, appugureedo.

    To give you a better "feel" for the word, kaizo is made up of the characters "to revise" and "to make". Among similar words using the first character are kaizen ("improvement") and kaishin ("repentment"), as well as kaichiku ("renovation (of buildings)"), kaikaku ("reformation") and kaizan ("tampering", also used for alteration of web pages). Words using the second character include zosen ("ship construction") and kenzobutsu ("building" or "construction").

    Basically, you'd use kaizo for something where you were altering an object, but not necessarily improving it; rather, converting it to meet your own needs. It's commonly used to describe the things that young males in Japan do to their cars or motorcycles; adding fins, spoilers, wide wheel wells, etc.

    Well, I have two points to make ..

    1) you were presumably trained or taught yourself, you must have made a mess of things a lot of times before you learnt ...

    2) you were presumably paid to have a skill to do this

    you said yourself you made mistakes, how many people who read these are going to be able to achieve this, the only reason it isn't hard to you is because you have practise. The real big danger here is someone is going to see this, and try it ... and then turn their Palm into a paperweight

    you make it sound simple, and I admit it is. but whilst what to do is simple enough, the actual doing of it isn't - it needs practise, skill and a steady hand. (or i suppose a powdered solder/flux mix you can paint on, and a soldering iron with a wide tip to heat a side at once :)

    Back to the main reason for this post though ..
    you say it is easy, when for 99% of people it isn't, and I had to point out the real world here :)

  • 1) you were presumably trained or taught yourself, you must have made a mess of things a lot of times before you learnt ...
    2) you were presumably paid to have a skill to do this

    Actually previous to that job I hadn't ever done SMT work or rework. I was an ace solderer though, having ruined a good many boards in my youth. That technique was taught to me at that job and while the first couple of boards didn't look all that hot, they did work (couple loose connections which when reflowed were fine). I was paid to solder them up using the technique they taught

    That technique isn't necessary on the M100, as the pins on the PSRAM aren't really fine pitch and you can touch each one without much trouble.

    The real big danger here is someone is going to see this, and try it ... and then turn their Palm into a paperweight

    They saw the pics... if they're ballsy enough to try it, then I guess they'd already weighed the risks associated with palm modifications.

    you make it sound simple, and I admit it is. but whilst what to do is simple enough, the actual doing of it isn't - it needs practise, skill and a steady hand.

    I agree... there is an amount of steadiness and skill to it. I had replied to your comment because you made it sound like a tantamount feat... it really isn't, and chances are unless you have a 900 degree iron or a 5W iron you'll mangle the board, but if you have a decent iron and the patience to do it, you'll do just fine.

    This is one hack that impresses me, for many reasons. Not the least of which, is the language. Perhaps I should get drunk, and write all my documentation in Japanese. The English page is great poetry- Too bad Slashdot won't allow tags so that I can do it proper justice.

    Molly, you just made my .sig. Thanks!

    First, nothing begins if not opening.

    Since the body isn't composed of glue like PalmV about m100,

    opening out is simple.

    But, it is because the used screw is special.

    " T5-Type" not too generally is necessary.

    I just got off the phone, with a vendor who had, until recently been supplying me with Expendable Bathythermographs. I've always liked their model "T5" probes because they range deeper and faster than anything currently available. Sadly, all that the vendor could tell me was, "they aren't too commonly requested, so we stopped making them."

    Damn. I need to consult slashdot before making any purchasing decisions in the future....

  • I got my Palm V upgraded from Tony Rudenko at http://www.palmpilotupgrade.com/. I just got it back today. Only 8 days after I sent it, and that includes a weekend. Check it out. It is really worth it. It does not even look like it was opened up! It is perfect! He also speeds up the CPU if you would like. He has also done over 100 of these with a 100% success rate. Give it a shot!

  • just bear in mind that not *everything* gets backed up in a hotsync

    As ashpool7 pointed out, you can force everything to be backed up by setting all the backup bits, and you can use a freeware program to set all the backup bits.

    For everyday use, I suggest BackupBuddy [backupbuddy.com]. Each and every HotSync will back up everything perfectly.

  • From an early age I have always taken things apart, but I have learnt my limits. I now do not mess with electronics on a board level, but I will disassemble everything that I can with the tools that I own. I recently inherited from a friend, a receiver which was intermitantly working, turned out to be a dusty power-switch ... I think that this is natural curiosity, and that people that do not pull things apart as soon as they get a chance have an underdeveloped sense of curiosity, and they are the oddballs. NF
