  1. UPDATE: After disassembling the PSU (which had tested faulty), it looks to be a transformer or a fuse on the voltage regulator board in the PSU. The model is seen as a Wan Nien 03c30-00011. Google has come out completely dry, and there is no way to determine what the transformer specs may have been. Has anybody ever gone this far into a PM PSU? The PSU is ACBEL-API9841

    Source for PB1x0 battery pack cases?

    Interesting, I still see some occasionally on eBay, you just need to be on the lookout. I still have my casings, probably should get them out and start making 3d prints of them. I may also still have some circuitry, but I would try if you could find the schematics, I think there are some lurking here.
  3. Thanks for the advice, I never thought about that. I will try to report back on what that gets me when I get the chance. PS: Love the car too, I have been using this username since 2011 when the 1 series was still a thing in the US, I never thought the 2 series would be a real BMW lol.
  4. I recently bought a Power Mac G4 Gigabit (450DP, 128MB) at a thrift shop. It was working when I tested it at the store, and it powered on and attempted to boot it. When I got home, I hooked it to my ADC Studio Display it powered on fine, but had a kernel panic before it could fully boot to the operating system. After taking the HDD out to replace it with another IDE drive, it now fails to so much as turn on. Different power cords and displays failed to repair this, as well as a CUDA, SMC, PMU and RAM reset, reseat, and replacement. I then put that to the side and two weeks ago picked up another PM G4 Gigabit for free at VCF East on the last day in an attempt to fix the other one. Got that home and also proceeded to power on at all. Nothing seems to be unseated, and I can only assume that I will need a new PSU, which I cannot find a good replacement for under $50, which is crazy. I am aware of the ATX-to-G4 PSU mod, but I would really prefer to still have the ADC power available to the Studio Display. Would it be possible to reflow the PSU? I have a guide that I am ready to use, but I am not sure that it will be a permanent fix? Any ideas on repair?

    3D Printing old PowerBook parts?

    Looks like this may have some more interest than I thought! I could certainly see what fabrications I could do to get some of these basic shapes molded. I was working with my PowerBook 150 last night, and to say the least, the plastics made sure that that was the last time the machine would ever be a whole unit again. Has anybody ever seen the actual chassis split? I knew the screen was common but I had never seen anything like what I saw last night. Thinking about it now, considering the costs of prototyping and manufacturing, it actually might be a good time to start looking at alternative ways to house PowerBooks with the plastic plague. Looking at how people sometimes make Raspberry Pi laptops and use housings. Or maybe make them look like slim desktops. Thanks everybody for the input! -M235i

    3D Printing old PowerBook parts?

    What about fabrication of just the hinge mounts? We should be able to just fuse together the rest of the frame.

    Thanks! As a sophomore in HS right now, I could only wish I was in an era where computers were moving at such a rate, and the colors so beautiful. All we have now are the standard black office Dells. They're great, don't get me wrong, but there just isn't anymore passion in them like they used to have. Oh well, I guess i'll settle for working on friends MacBook Pro's and laughing at them when they complain of the keyboards breaking and screens discoloring when they (well, parents) spent $2000 on a machine.

    PowerBook 5300ce

    That would be correct. I'm thinking of trying to get this machine back in working order, but if it becomes unfeasible (which is a real possibility), I will be parting out the system. I will make sure the lcd makes it to you in that case.

    PowerBook 5300ce

    Lucky find, my 5300ce I got recently will need a complete rebuild. Crumbled in my hand as I got it out of the shipping box. Oh well. I think yours would just need the solder for the DC Board.

    M235i Thread of Finds!

    I feel like this is something that I should've started a long time ago. Here and there, I acquire some finds that I just need to share. Sometimes they show up on the r/VintageApple sub, but I think it is time to start logging it in one place too. I will be showing some of the more recent finds from the past year or so, starting with one of the most recent catches, then moving to the stuff that falls into my hands as they come. First Up, my newest catch, a Rev A. iMac G3. IOB with everything down to the plastic protectors that came with the computer in shipping. Price - Free. Really pays to have people looking out for you on the FaceBook Swap groups. Met the seller, turned out it was her first computer that she had purchased with her own money and was her first time on the internet as well. She couldn't see it go to the recycler but needed it gone. I was happy to take into my wings a machine so incredibly clean. I'll let the photos speak for themselves. Rev_A._iMac_Find.zip

    PowerTower Pro 225

    And the ability to offer these machines at lower prices with smaller overhead that Apple could not do because of the use of more generic components. Also, clone companies could release to a more specific market sector quicker. Also, since the market share for the clone companies was smaller than Apple, and more (cheaper) DP server market components were placed in over the proprietary MP cards, the lower price almost made it impossible for Apple to make similar spec machines at any lower a cost.

    What is the current view on these hard drives?

    Just want to take a look at all of the drives that are used in old Macs (and PC's). Hopefully this helps if a replacement drive is needed in the future. Frankly, the best luck I have had with the slew of hard drives I have had, the Quantum's always seem to be the easiest to fix, but almost always arrive seemingly dead. It takes removing the cover and playing with the head and the stopper to get them working again. Once you do that, usually they are good to run for a while, even be stored in both hot and cold climates. Stat wise, of the 13 Quantum drives that I have, 2 have died (1 DOA and 1 that had something go wrong, only to scratch the platter). Honestly it is a shame that many of the drives (and as a result the computers they are in) get tossed as a result of gummy rubber. All you need is 10 minutes and a PSU to get them working again after 20+ years of dormancy. Prices for a working one are through the roof, but a 'broken' one can be had for under $20. That quick fix or a little diagnosing usually has the little bugger running. The Connor SCSI and IDE drives always arrive DOA or on their last legs, usually when I get a Mac with one of those things they are backed up (if their is anything worth backing) and then run until they die, which happens pretty soon after. They are usually either gummy or the boards running them are on the fritz. Also not very fun to take apart. They are a little pricey for what they are, but are cheaper then almost any Quantum. The Seagate drives will always work, albeit very loudly as echoed above. Never have needed to take one apart (knock on wood), but of the 5 or so I have in Macs and PC's they have never let me down. As a result though, they are some of the most expensive types to get, and are getting rare to find (for SCSI at least). Maxtor drives... oh boy. I honestly believe they arrived from the factory broken. I have never actually seen one run properly for more than 20 minutes, either on PC or Mac. The only reason to have one is to look at the chrome plated models (which look really good) that I have lying around, but otherwise, avoid like the plague. IBM drives also seem to have excellent reliability in anything they were put in. I have Travelstar's in quite a few laptops and they never give me an issue. They are great laptop drives, but the desktop models can be a little more sporadic and finicky. Prices are all over the place, I have seen some go for $20-$80 for the same working model. Just a matter or watching the market. The only other HDD I can think of are WD's. They have never let me down, but I do not see them in older Macs at all. So YMMV.
  13. Just an idea that came to my mind when working on both my PowerBook 5300ce and 150. Both of them suffer from that PITA hinge and stress cracking issue. Both have the standoffs ripped off the housing and the 5300 is literally crumbling with the Rev. A plastics. As the 5300 fell apart in my hand and more fragments of plastic than actual computer piled up next to it, I looked at the other piece of the screen assembly and it occured to me. The chances of finding new assemblies or housings for these things are becoming harder and harder everyday, with most (if not soon to be all) eventually having it crack. Why have we not assembled 3d printed case part replacements? I would believe the filament would be strong enough to hold the very tight and overpowered metal hinges (for at least a while), and it would not be that hard to model the standoffs and the threads for the screws into the moulding. Almost all of the PowerBooks using ABS plastics can have the housings fit into a printing tray for fabrication. I still have the parts from both models that people could use to assemble a proper model of it. I have the basic knowledge of 3d modeling, but I would like to know if anybody here has had any luck with the printing of cases, housings or assemblies. And if not, should I atleast see what it would take for that to occur?
  14. I'll throw my 2 cents in quickly. Surprised no one mentioned in detail the Power Mac G4's as a bridge unit. It is one of the best Macs you can get. The fastest to run OS 9 natively (dual 1.25 7450e's in the '02 MDD), excellent in Tiger or Leopard, ample connectivity for everything under the mac sun (USB, FW, PCI, etc), and the early ones also have Zip drive support.

    Free Clamshell iBook!

    Saw this on /r/VintageApple subreddit a couple of minutes ago. I'll echo what everyone else has been saying, it is a really nice find! I thought I was lucky finding an iBook Clamshell 466 in Graphite for $25 with the same accessories you got. I have the same thing with the battery. I even recelled mine last year and it looks like it gave up when in storage. I tried that Battery Updater but it only works with the M2453 models, so M6411 owners are out of luck when it comes to that type of reset. Good luck getting it all back up to spec!
