    G4 MDD not booting

    Sadly no, I'll be waiting to find a replacement CPU to try. Good luck 🤞

    Recommendations for SCSI disk recovery software

    Not SCSI specific, but it should work, GNU ddrescue can make an image by doing several passes, skipping bad blocks first, then scrubbing them to get the most of them. Works on Linux, probably also on OSX. Once you have a raw image you can convert to dmg or whatever and work from that with tools...

    Reverse Engineering the Macintosh LC III Logicboard

    Looks like you'll have to file the 96-pin one and cut into a 21-pin to get the 18-pin extension… Maybe a hot-wire would work for that.

    Reverse Engineering the Macintosh LC III Logicboard

    Almost ashamed I successfully recapped my LC-III last year :p

    Open Source 68-Pin 512kb VRAM

    Oh no it's not about you or your project, I want it to be useful to the most people, I just genuinely don't trust online services to be available for eternity so I was concerned about long term. Sorry if that sounded mean. I don't have KiCAD installed on my new laptop yet but I can have a try...

    Open Source 68-Pin 512kb VRAM

    Ah ok so the source is available but on some cloud instead of the git repo. At least it's public. Let's just hope the cloud doesn't vanish :)

    Open Source 68-Pin 512kb VRAM

    Also, putting zip files in an SCM kinda defeats the purpose of it, you can't diff it (yes, with git it's even possible to visually diff gerber files)… But for that you need to have them directly in. It will also make the git repo smaller since git will only store the text diff between versions...

    Open Source 68-Pin 512kb VRAM

    Hmm why only PDF for the schematics? The "source" in Open Source means source, not a screengrab of it :p

    G4 MDD not booting

    I already tried various combinations, and I just did again with two more PC2700 sticks I had around, nothing worked.

    Reverse Engineering the Macintosh LC III Logicboard

    Well I would maybe if I didn't have so many projects already. And then I'd do it in KiCAD anyway so it probably wouldn't match with the PCB which would be a shame.

    Reverse Engineering the Macintosh LC III Logicboard

    Yeah but modifying the PCB without the schematics would be harder without at least a netlist for checks.

    G4 MDD not booting

    Just tried, didn't work any better. In fact it doesn't even beep for no RAM, just sits there, and after 10s it maxes out the fan as it'd do after a PMU reset. Putting back the original PSU gives the original behavior again. I didn't have all wires available, I only had one for 12V, but I doubt...

    Reverse Engineering the Macintosh LC III Logicboard

    Well, schematics available as ugly bitmap scans and schematics in a usable format is different but yeah…

    Reverse Engineering the Macintosh LC III Logicboard

    Are you just doing the PCB directly or the schematics also? Could be interesting to be able to patch it. At least to add a switch/jumper for overclocking :)

    Qemu can now emulate a Quadra 800 and run A/UX 3.x

    Cool I'll be able to use that for my Haiku port then :cool: There has been a presentation of the 68K status for QEMU last year for one of the M68K talks.

    I made a short video expressing my love for the black Performa 5400

    I've heard several times this advice on screws: turn it reverse until falls in the original thread, then it should get back in again. Not sure it works all the times though.

    I made a short video expressing my love for the black Performa 5400

    Very well filmed video! I also happen to have a 5400 black… Beauty. It's sadly sleeping in a box for now, I should give it some more love. :)

    G4 MDD not booting

    Ah yeah I forgot to mention I did verify all the voltages from the PSU as well as per this doc. But maybe it's still weak, at least I do have ATX PSUs handy.
