Following this closely as I've tried the SRAM + memory hole punch before and failed Already learned a lot as usual. I hope you will be successful in your build

Found this while looking for something else: the PB140-460 connector (60 pin one) is still manufactured, although it's a revised design (extra metal clip). Unfortunately this design isn't available in 72 pins. Reference is TE Connectivity 2-111196-2. It even still has the old AMP logo from the...

Hello, From having replicated the MacSnap SCSI with the help of a few other members here, I can tell you this thing is very sensitive, either by its design or the old ROM sockets. First the broken pin isn't an issue, it isn't connected to anything. All of the boards are like this Second...

Tim & Dart based PowerBooks do not get to the floppy icon if the HDD is dead and is blocking the SCSI bus, they are stuck at the gray screen Pretty sure the 170 with display the floppy icon if you remove the HDD. Also the logic boards are fully solid, no need to recap theses

Got it. That's an old unsupported mode which doesn't work anymore due to Bluetooth security updates. It never worked with MacOS. I think you are the first person to use it. With 1.4.4 you can try with the pin 484848, it worked on Windows 10 back then

Always nice to have options, good job! Yeah it's kinda short but sufficient enough if the mouse is near the Mac. Can always use a straight serial cable as an extender

Hello, Had theses around, figured I could make a guide on how to convert them to use with old Macs. VTech is a company that did Apple II clones, and later education computers. This mouse was designed to be used with such computers, but the circuity is compatible with early Macs. It's a fully...

Probably dead hard drive. Most of them are dead at this point. The fact that the grey screen show up is a good sign however

You are too fast. Impressive work. -12V is for audio right ?

Not sure if that's what you are asking, but, shortly after boot, the adapter will scan for a mouse in pairing mode around and connect to it. Subsequent boot does not require the mouse to be in pairing mode

I've got a few of theses. Some were indeed privacy filters The other type was a filter supposed to reduce eye fatigue similar to what theses yellow glasses do today with LCDs. It worked somewhat well, at least on screens where low refresh rate was an issue (< 75 Hz for me) Some had additional...

What was written on the CPU itself ?

They are indeed fragile, you can replace them, but will have to remove/replace the ROM sockets first

Thanks everyone! Documentation has been pushed to the GitHub, should be good enough so everyone than can build one. Let me know if something need to be improved As for the limits of this board, there is a couple of limitations which are present on the original as well. Sockets First main...

Is this a real 1.4 Ghz die ? I remember having a few gigadesign back then, and they were factory overclocked, and never stable. The only way I could get it remotely stable was to reduce speed a little bit closer to the non overclocked G4 speed and this abomination: Before going to this, as...
