I picked up a B&W G3 with an OWC450 G4 in it that would not boot. Put that 450Mhz G4 into a beige G3 and got it up to 533MHz.

I ordered a Lo-tech ISA XT CF Adapter rev. 3 so I can add a CF card for a hard drive. I have to start somewhere, so I found an old Pentium 233 and installed DOS 6.22 on an internal CF card. I was then able to format a 720K floppy to use in a 3.5" drive on the Sperry. And the Sperry might...

I completed the analog board recap. Since I swapped tubes with a Macintosh Classic, the tube in the Frankenstein will be white. I thought I found the correct pinout for the keybaord, but maybe not. Since the keyboard I have is assumed to be XT and not AT, I assume it should direct connect...

I hereby nominate myself for a vacant position. Over the last few years, this forum has changed me in many positive ways. I have expanded my collection, my knowledge, my participation in this community, and my interest in tinkering. I plan to retire from full-time work in the next 2-3 years...

Now the swap! 700Mhz screen into the 1GHz machine! The Pressure marks are gone! But the center looks dark. This will be a candidate for PPC Challenge 2027 for CCFL to LED conversion. To the LCD panel pulled: definitely different, but identical functionality. This one had an additional...

I have a 1GHz 15" with some screen smudges, so I want to swap out the screen anyway. I have a non-functioning 700MHz G4 that will be the donor. The iFixIt teardown getting to step 8, that is NOT the screen code you need (it appears to match the serial number). The panel code is under the...

Being that there were three/four different variants of the G4 15", which do you have? They may have different panels internal, depending on model. Once you know which one you have, finding a similar panel equivalent on Panelook.com might help in your search. I am going to assume it is some...

Use an iFixIt gude to disassemble, then find the LCD panel number on the back, then check your standard eBay, Amazon, etc for that model.

I think there is... And the sub to that is:

No chime? Do you have a wired USB keyboard you can do a PRAM reset on? Check the voltage on the CMOS battery? Correct PSU? The G4 Mac Mini uses the same plug but is only 84W (A1105 model).

TLDR; Picked up for parts cheap, intent was to steal the tube for a green Macintosh Classic (completed). Can I fix the rest? This is what the machine should look like. It goes by many names like Olivetti M18, Cordata (Corona Data Systems) PC-400 or PPC400-XT. But mine was missing the...

I stopped by Free Geek yesterday and found another G5 project. $5, no graphics card, missing the acrylic air deflector, no hdd, no ram. Single processor, dual core, 2.0GHz. I added all the spare parts needed, and it fired right up. And then I remembered I had a spare dual core processor that...

How long is it? Maybe these on eBay?

Here is some more reading for you, maybe it will help.
