nice, I'll give it a try. I maintain a DokuWiki, and I stick a QR code to the devices that links to the URI. The URI is uniquely defined by the device serial number. I use the phone to scan the QR code and land on its web page. It's useful to generate the QR Code from your system. I currently...

instead of going “horizontally”, I’d now take the time to check all the traces, starting from the address lines, and the video circuits. Another option is debugging the boot sequenze using the serial output, checkout for Adrian Black video

Thanks mate, I do use 'dd', especially in the past with the previous generation of SCSI emulators; now they use file images instead. What is the deal with DumbDD?

I see a lot of enthusiasm here—that’s great. That said, speaking as a layman, could someone please clearly outline the expected use cases for this “DumbDD” app?

for the records: I used a Mac mini 2011 running High Sierra to install macOS onto an external SSD via USB. I then moved that SSD inside the iMac using a 3d printed frame. Everything works correctly. The only minor issue is that: - The system identifies the Mac as a Mac mini (the icon shows a...

Did you try it yourself? When I attempted the same procedure on a 2011 MacBook, Internet Recovery failed with a “server not available” error. I also tried the commonly suggested workaround of changing the system date via Terminal (e.g., using date before starting the recovery), but it didn’t...

@bibilit , is an ISO image just fine?

All the cables were unplugged, and the hard drive and SIMMs were removed. I managed to get it to boot; it’s now (as expected) stuck at the “?”. Next, I’ll install a new glass panel and an SSD. However, as with many older iMacs, I’m having trouble creating a bootable macOS USB installer from my...

I got this iMac for free. https://support.apple.com/en-us/111983 It does not boot, "BEEP BEEP" ... and without the glass ... it could be my file server for the other macs

I've updated it to 10.3.9, and it seems to fly pretty well to me. I read different suggestions here about downgrading it to even 9.2.2 or 10.1, why? But yes, it depends on how I want to use it :) At the moment it will sit in the livingroom to show its nice design and to let friends play music...

I’m quite happy with this. The colors of the picture are false, the Mac itself is pure white while the keyboard is terribly yellow, so a bit also the mouse. The speakers are perfect! Ah, I have the box. I’m planning for RAM upgrade. Any recommendations for the MacOS X upgrade?

@leonlas , I'm sorry, I can not tell

I have a decent SE/30 logic board, slightly affected by battery acid. After adding a couple of bodge wires, it works almost perfectly. I replaced the original RTC with a new ATTiny RTC module. I installed 4 × 4 MB SIMMs in Bank 0 (16 MB total). The machine boots in 32-bit mode using a BMOW...

thanks, can u pls provide the URL? I got this https://www.utsource.net/sch/CY7C128A-20VC.html Replacement Models If the CY7C128A-20VC is unavailable or obsolete, consider the following alternative models: CY7C128A-25VC CY7C128A-35VC
