  1. Thanks, Can you shoot me Bruce’s details (or better still e-introduce me. I am at timhd@outlook.com) as keen to get the old girl working again. While  I am not in a hurry to get it fixed asap, as these are fun pastime projects, I likewise  don’t want to ‘try’ and wreck such a rare item as a CE) trying to recap it myself.

     

    Ps - If you’re keen to do it, I can wait til your freer or I can see if Bruce is up. After all, once I’ve played with it a while I might be prepared to flick it to you to play with or buy or something as I really jut like getting these old systems and maxing them out and then either have them on display or sell them to another enthusiast one day.

    I agree with Byrd, caps on the DC board are bulged, a common issue on the 5300, will prevent the 5300 from booting or do any strange things.

    Thanks. Yes, I would say so. Re-assembled again and noticed this time the screen cutting out during booting up, which I presume means not enough power coming through.

     

    Anyone in Australia handy enough to replace the caps (looks like 100uf35V caps) as am not handy enough with the replacement techniques and these are rare enough.

    Alternatively, as the power board is quite small, I'd be prepared to ship to the USA if someone wanted to do the repairs for a fee?

    First of all it sounds like power issues are your main issue initially - the 5300 have highly delicate DC jacks and it could be booting off battery (perhaps it has a little charge) than from mains power.  The caps on the DC power board also look a bit bulged - those 100uf 35V ones you have pictured.  I'd be cleaning the DC board with electrical contact cleaner (Bunnings sell it now, WD40 branded) - and do the same cleaning on the RAM and other connectors.

    Thanks for the tips @Byrd. I am actually without any battery for this (but am aware PBs don't need them nor PRAM battery to run on AC power). I think the power supply is good as I've run the PB for quite some time doing various reboots and PRAM resets etc and it only seems to crash at the same stage in the startup. Hence I suspect though it at that stage  of the startup that the HDD and maybe the display (or whatever else is being pinged - maybe FDD check - at the startup is just sucking down too much power from the power board and it dies - so the most likely culprit is the power board.

     

    I didn't think the caps looked bulged, but then I am no expert on this. Anyone out there able to replace caps on just the power supply board? (used to send MBs to Maccaps etc) - as that seems to be a common thread in past discussions and something that will need a repair at some stage.


  4. I recently acquired a 'cosmetically good' PowerBook 5300ce that had some issues. I've had a few attempts to work through the symptoms using the Service Source and reading other Forum posts, but am having little success getting it up and running and would ask for any further tips you have (short of recapping etc, but appreciate that might be a cause/something needed). The seller acknowledged it had some issues when booting ('occasionally operational' eBay Link) and as such it either gets to (i) Mac Chimes of Death (4/8 chimes); (ii) Restart - Bomb ("Bus Error"?) or (iii) failing to boot (Hard Drive shuts down mid boot as Finder Screen is being populated).

     

    I've done a basic strip down and re-assemble and noted that I can solve the first 2 issues via (i) removing/reseating the RAM Board (NB: the PB seems to be missing the GASKET under the keyboard which might mean the RAM Board is slipping out - any tips as to what makes a good substitute as a small foam insert (5mm high) seems too much?) and (ii) booting with Extensions Off (Shift). But despite a check of the various components and careful re-assembly, I still find the PB is shutting down mid-boot (Hard Drive shuts down hard, screen goes black).

     

    A secondary issue/symptom is that the PB boots once the PS is plugged in. I have done the PRAM reset and Power Manager Reset (per the Service Source Manuals) and can see no visual issues with the Power Board (no bloated caps or goo visible) short of electrical testing. The Hard Drive seems to be ok (per the eBay images, it can boot) but I seem to not to be getting that far, crashing about 10-15 seconds after booting with Extensions Off and just as the Finder is setting up the Desktop (don't get as far as seeing any icons, but it does get past the extensions/boot screen).

     

    The PB has no battery, which appears to have leaked a little, but not onto the MB as far as I can see - it appears to have corroded 2 of the pins on the battery connector - so I am booting from mains with the correct Apple PB 45W power supply - see image gallery for high res details.

     

    Welcome any suggestions you have for next steps to help get this going again in its full 800x600 603e 117Mhz 32MB splendour.

    Hi GuidoB,

     

    Would you be so good as to make DiskCopy 4.2 images of the disks and put them up on to Macintosh Garden, Cory's VTools or somewhere where they can be easily accessed please?

    I can imagine myself stumbling upon this thread in 8 years' time looking for these drivers hoping to find for a link to them.

    @ArmorAlley, I will do that once I confirm the files work fine. It’s the least I could do, given Guido’s already helped me and so that others like me, don’t hit the same problem (I was amazed that 3 of the versions on Macintosh Garden just have a text file in them saying, Oh BTW Disk X is corrupt, but no mention in the title to the file that the set is incomplete!)  

     

    Thanks again @GuidoB for helping me out.


  6. Does anyone have a complete set of the PaperPort Vx SCSI drivers?

     

    https://www.macintoshrepository.org/2558-paperport-vx

     

    As per above link, MR has lots of drivers for the Serial (standard) configuration, but I am running mine via a SCSI cable and it needs different drivers. The Repository has 2 lots of PaperPort Vx 3.5 SCSI.sit (StuffIt Archives), but both of these say Disk 3 was corrupt and thus the other 2 .sit files are useless without the missing disk!

     

    Does anyone have a working Visioneer Disk 3 with the SCSI drivers that they could create a DiskCopy4.2 image for an upload it to MR / and or send it to me? 

     

     

     


  7. Any chance the Asante Card is conflicting with the Nubus Pivot?

    The Asante Maccon manuals talk about the need to swap a jumper to change the address setting when installing them aside Radius Pivots (say in a IIsi). I had this issue on a IIsi I was installing an Asante card with a Radius card. Appreciate that Iici is not the same type (Nubus vs PDS) but could that be a possibility why it not comes up?. 


  8. So, an update on this project.

     

    I got some more time to re-check things and tried the 0379 Color Pivot LE with my SE/30 Color Pivot card again recently.

     

    Here's what I got at first try... but leaving things for a bit of time, I started to notice a bit of a pattern and turning up the brightness/contrast seemed to speed things up...

     

    So as it warms up, we get a better picture until perfect after about 5 mins... Thoughts on what the issue is - I presume it's the monitor, not the card?

     

    NB: Earlier post with the purple/blue line was the SE/30 Pivot card (not color) which outputs on Blue until you wire R-G-B lines to get monochrome pivot on some monitors (LCD etc).

    Link seems not to work, but I managed to unpick it and I think this is what you were referencing as first hit (among others on a similar thread). https://aronnelson.com/aron/duoTick.html This, like others, identifies C28 as the culprit. Will give it a go.

     

    NB: The PowerBook Duo 230 is going well again. Did a strip and reassemble after I noted some comments re importance of one of the screws needing to be in solid to help grounding or something. Working like a champ now. If only the Duo Dock was that easy to get going! Ta

    There's a single component in the original DuoDock's PSU that's a very common failure point. Don't recall offhand, but it is or was a well documented fix. Mine failed back in the day, fixed it and it's still working.

    Do you recall what tests you did to fix the error (eg multimeter check on traces etc or are we talking transistor/chip level replacement that got it going)?


  11. Anyone tried to get a DuoDock working lately? I got one that was supposed to be working, but doesn't. Did a basic strip down, everything looks ok, not entirely sure where to start - was going to research what common issues are for the Duo Docks.

     

    Separately, my Duo 230 boots for 20-30 seconds then just stops. Sometimes it goes for longer, sometimes shorter. Not sure what is causing that, but see it seems to be common and might be IC/transistor related though the differing cut out seems to suggest heat related (as need to leave it off for 5 mins before I can coax it to boot again).

     

    Any thoughts from those who've had a play with Duos and their Docks.

    Yes, When I replaced that cap, the problem went away.  IT was a 22uF, 25V electrolytic cap. I also replaced the 10uF 50V cap while I was there. You have to pull the covers, then remove the AC power block

    (4 screws)

    Then remove the fan shroud and fan,  and pull the circuit boards from the AC power block.  The caps are on the small controller board.

     

    Do you mean the "High-Voltage Power Supply" per the Service Source manual, or was it on the DC board or DC power supply? (Haven't been inside the iintx for a while - recall it was quite a disassembly but I went all the way in to check everything as best I could.

  13. Per the LC Series User Manual  Macintosh LC Series/ Quadra 605 - tim.id.au there's a few to choose from.

    You could google for images to get a look at what they look like and whether they'll go with your LC 475:

     

    LC and LC II provide built-in support for many monitors, including: 

    • Apple High-Resolution Monochrome Monitor (M0400) 

    • AppleColor High-Resolution RGB Monitor (M0401) Rev 2 (M1297)

    • Macintosh 12-Inch RGB Display (M1296)
    • Macintosh 12-Inch Monochrome Display (M0400)

    • Macintosh Color Display (M1212)

    • Apple Basic Color Monitor (M9103)

     

    LC III, LC 475 and Quadra 605 provide up to 16-bit support on 12-, 13-, and 16-inch monitors and 8-bit support on 15- inch portrait and 21-inch monitors. LC III, LC 475 and Quadra 605 support all Apple monitors available at CPU introduction dates, including:

    [as above plus] 

    • Macintosh 16-Inch Color Display (Macintosh LC III only)

    LC III, LC 475 and Quadra 605 support NTSC and PAL. 


  14. I acquired a later revision Apple Multiple Scan 15” Display - Model M2978, Nov 1995. (Ie this one is different to the model (M2943) you commonly see in the Apple manuals by this name, which was originally introduced in mid 1994.)

    When the monitor powers on, the green LEDs below Horizonal/vertical centre/size indicators cycle from left to right continuously. The monitor's main power LED remains orange, and does not flick over to the ‘on’ green indicator as normally happens when a Mac boots up and sends images to the monitor.

     

    Anyone have a manual for this older variant or could tell me what this means? Is it not getting a signal (this Model has a vga female port on back whereas the earlier model had no plug with the cable running from the back to the standard Mac DE15 monitor connector and I believe the connector I have is the right one.
