Apologies newish to the G4 lineup. So haven’t done too too much but yeah makes sense for units that shipped with those external speakers. Rookie mistake on my end. These came out literally the year before I was born so want to learn more about potentially modifying these and so forth. I suppose...

I can't find a data sheet for the Lucent 1258U, also the Lucent chip on the G4 Cube is a Lucent 1258AK5 (Don't know the difference). If I can get that that should actually give us what we need. Because you are right pins 16 and 15 on the 3550 control in out sound clock and data.

I’ll try looking into the connection there as you mentioned and see if it works. If not I believe it really is something in the software that was just never finished and removed altogether as a result.

I've been slowly discovering a lot about the G4 Cube which in my opinion is one of the best looking Mac's Apple ever made. After looking for one for a while my good friend @Jockelill gave me a great deal on one and I've been loving the device a whole lot since receiving it. I've slowly...

Absolutely if you need me to confirm what caps are said values just ask.

Here you are:

Realize this looks like nutrition facts

Absolutely that would be awesome if you did. I’ll take some better photos tonight of the boards and upload them here.

Hey everyone I made a recap guide for the STB. This guide is for the STB3 (not the much rarer STB1) but I also decided to make a teardown guide on fixit in case some of you are a little uncomfortable trying to see how to disassemble this device. I also wanted to clear up a common myth or two...

That's so odd even looking at chip date codes none of this makes sense I guess maybe they had separate teams with different plans and who's ever design was cheaper and more efficient won. Or maybe it was for a team developing the network interface or something and they had an odd case. Then...

I’ll take some of mine right now. But that EGRET is odd. The case looks right for a DVT stage but what's odd is the ROMs are soldered my best guess is this is a very late updated model they were planning maybe? Maybe plans for something like in the 6400 with a split riser in an updated EVT stage...

can you drop the 7200 and 6500 too? Thanks in advance :)

If you have a 1.2 Amp Lisa Power Supply there's finally a published List now.

It’s a work in progress @max1zzz has updated the PCBs and sold the first few prototypes. This is a great tool for testing Vias, sound chips, scsi interface, cpu, and rom status, and even voltage. Works the same as a TechStep normally would except you select which rom variant through DIP...

Oh yeah I’ve got 10 more I’m getting from him. Be warned every single one I’ve gotten needs work and some have had battery damage so make sure you pull those boards out.

Needs ADB soft power (keyboard power on) to boot up, similar to a Color Classic. Also if it doesn’t chime, the led is on, the screen is black, and the fan is running add RAM. If you need RAM it’s the RAM G4 and G3 Mac’s take do not force a random 168 pin simm in.

What is it doing, any sounds or is it a black screen, no chime, fan spins, no led situation? And yes I'm in NC.

Hey everyone thought I'd make this list and share it with everyone. I know there has been a post about the logic board recap guide HERE , Thank you to @shadedream for that! And before you ask yes, the Beige PowerMacintosh G3 and the PowerMacintosh G3 All In One share the same logic board...
