Interested in seeing how you're going to restore the chassis. I like the original industrial steel look and I don't really know how to bring that finish back and 'metal' paint just doesn't cut it for me. Perhaps sanding would help?

How is the RTC doing? It’s an Apple part so you’ll never find a replacement unless you get one from another Mac... If it’s doing fine, then you can go trace hunting. Oscillators and diodes should be referenced in the schematic.

A demo can be found on the MacGUI. That's all I could find I'm afraid...

Yup. Technically, it should work. And if you want to use a larger pre-made image, download one from this tutorial (I used it to set up my SCSI2SD, and it's a more complete version of what I've written...

Cory already replied to this one. Mine's still got the High Sierra BootROM, I haven't tried updating it because I can't install Mojave and I'm not using NVMe SSDs anyway. The RX5700 looks like a great card to replace the 1080Ti with, which I have to UNDERclock in order for it to work properly...

I upgraded my 2016 Macbook to Catalina on day 1 and everything works fine, except the Basilisk II GUI (as @pcamen already pointed out). No Mail.app problems at all. The only thing that bothers me is the lack of Airdrop support for older macs.... I have Mavericks on the machine I'm typing this...

@HeartletTullius Blank image as in blank .img or .dsk 'hard disk' image. An image is basically a file that once opened (mounted) behaves just like a normal USB or SD card (i.e. a volume), you can then access its contents just as usual.  So... First, open up Disk Utility, select your SD card...

Basically, you need to find a blank image, use Basilisk to install Mac OS onto it (plenty of guides online on how to do that), and then use dd (terminal) to write it onto the previously set up SD card (standard procedure, use scsi2sd-util for that).

A couple years ago, I got in touch with Lapis’ former CEO about their SE/30 color card. He told me they never got to publish 7.5 friendly drivers for any of their cards...

I've had to find another workshop as the first one wasn't really interested. The second one I've found is great though. This guy services industrial grade PSUs but he's also a 'Funk' collector (ie radios, TVs, talkie walkies, CB etc.) and an Apple aficionado. He worked on a few Lisas and has a...

Interested in the outcome of your research, Bolle... My SE/30 also has this issue but somehow it's worse. The wiggling occurs on about 1cm. Mind you, the Analog board is still 100% stock (PSU, LB recapped).

Seems like I'm starting a monologue here... Anyway, the /PFW wire is indeed getting around 5V (4.4V in my case. FYI, the ATXs work by shorting the green Pwr_ON wire to ground, i.e. the other way round). The soft power circuitry must be using the 5V trickle line but the latter isn't directly...

Okay, interesting, so it doesn't like loads. 

Nevermind what I said above. This doesn't actually mean anything as the 'load' isn't purely resistive. If it had been 0 or really close to 0, then it would have been a problem.  Knowing this, I felt pretty confident about plugging it in for yet another smoke test.  And it booted right up. I...

Well, today I got the multimeter out, and noticed that the entire 5V rail appears to be shorted to ground: there's only 26Ohms of resistance between the two and the multimeter in continuity mode beeps so that can't be good, right? 

Hi all To keep things short and simple, I am now in a situation that prevents me from devoting as much time to the hobby as I'd want to. Don't worry, I'll come back to it in a few months, my passion for Macs hasn't gone away at all. There's just more important 'life' things going on at the...

Makes sense. But 28A should be enough, right?

Okay, I've done more research on PSUs.  The original Quadra PSU outputs the following voltages: +5V Trickle 'Constinuous' @ 1.25A +5V 'Normal' @ 33A -12V @ 1A +12V (a) @ 5A +12V (b) @ 5A Modern PSUs can output most of the voltages above with a higher amperage, except for the 5V rail. This...

Great to hear that it works as expected. The more I think of it, the more I think that the 'locked' behaviour must be handled by the logicboard. It must send some sort of repetitive signal to the PSU to tell it to start up. The only thing I have left to do before kickoff is to select a proper...

There’s no speaker connector on the classic II, just like the Plus it’s integrated in the main LB connector.  Is sound working after boot up? You can check this with a system 6.0.8L (make sure there’s an L!) boot disk by navigating to the sounds control panel and adjusting the volume from...
