Interesting as 640x870 is the default resolution (though 75Hz is the correct setting) for the Apple Portrait Displays: https://lowendmac.com/1989/macintosh-portrait-display/ http://web.archive.org/web/20080112161619/http://docs.info.apple.com/article.html?artnum=4815 See also this article...

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)...

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...

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...

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...

@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...

Great. Thanks

Bump. Anyone?

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...

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...

Finally, about there (a minute later, all good and pivoting fine).

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...

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...

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)?

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...

Any update on this? Looking to do something similar.

Great idea. Haven’t managed to get A/UX working on anything yet - so not sure if I am a good test subject, but happy to assist however I can. 

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.

I had similar scenario with my NTX. Did replacing the AC power block capacitor fix everything? Where is it located so I can test/replace?

Great work! I'd be interested in getting 8 simms if you do end up making a production run of these. I'm sure here must be some others on here after those SIMMS and have no way of producing their own!
