I just picked up an old Cinema Display and Apple Cube speakers. I tried connecting the display to my powermac g4 as it was the only comp I had which had the same display connector and it wouldn't power on. Also, the cube speakers seem to get power through the amplifier.

Questions are:

Is the display shot or does the powermac not have the capabilities to power a display like this?


How can I use the cube speakers?

I had to search around a little about those Cube speakers. They get power, and audio, through the USB port. They are sold as working only with the USB port on the cube, which has more power than standard USB ports. You can also plug into the USB ports on certain Apple displays - those that are powered through an ADC connector.

There's some more info: http://www.ebay.com/itm/APPLE-PowerMac-G4-Cube-Pro-USB-Speakers-M7963-06-2G-/141257465893?_trksid=p2054897.l5658

The cube speakers probably won't work on anything else, although you could probably cut off the amplifier and solder new RCA connectors. The same instructions for the standard Apple Pro speakers should work, I suppose.

I think you have to connect an ADB line to get the display to work (or at least change any settings) - but I might be wrong on that...

Got them plugged into the back of my other Cinema Display and no sound. Does the amp have to be plugged in also?


----------

Solved! I had to change the output settings. Any idea about the screen?

Try plugging them straight into the PMG4. If that doesn't work, try switching the output in Sys Prefs. I know the driver was in OS X through 10.6.3, which was Intel only, so in theory they should work with any PPC Mac running OS X (maybe even OS 9, but the driver may have only been in the Cube's version of OS 9).

If you ever want to sell them, let me know. Mine are trashed.

Also, that first display you pictured won't work. Your G4 looks to have VGA and ADC, those displays used the old DB-15 connector found on Old-World ROMed Macs (Beige G3s and earlier).

Cube speakers will work with any Mac with a USB port that is running OS 9.0.4 through 10.9.2, with the exclusion of 10.6.3-10.6.8. When used with standard power USB ports, the Cube speakers will not work at their maximum designed volume. Macs that can drive them at their maximum volume include the G4 Cube, acrylic Studio displays, and most Intell Macs made after mid-2007.

The blue Studio display you posted a picture of is the middle model of that line that has a VGA port. Your G4 has a VGA port and with a working power supply for the Studio display, it'll work with it. The ADB port does not need to be connected for it to work. Make sure the video source is set to computer, not video in.

I plugged it into the g4 vga port and nothing doing. Is it possibly it's just busted?

There's an external power brick for that display - 24VDC, I think. Can you measure voltage on that power supply?
It's possible that the video board in the display has given out. Be sure to try the display on other computers. It's a standard VGA connector, so should work on anything with a VGA output - doesn't need to be a Mac. (That's not to say that the video will be good, as there could be driver issues on a Windows system, but the screen should light up, and you should get _something_ generic/blocky on the screen.

Do you get ANY indication on the screen? Power light blinking or changing color?

Those old B&W Studio displays work well on any VGA computer, no drivers needed. They're rather dim and have a low resolution of 1024x768.

So far so good. The powerbrick is very damages but wires are hanging on. Screen is so cool and I'm glad I found these for sale!


Too bad I can't connect it to my g5 though

Actually the speakers are connected to my g5 as I have a set of imac g4/powermac g4 speakers for this already. Just found the screen and speakers for sale and couldn't resist.

The brick is shot but works. I can feel heat coming from it and it's buzzing. Hopefully I can find something to replace it.

733mhz so it's kinda slow compared to my 1.8dual g5 but has grown on me!

Huh. I didn't know they made with one with a VGA port. Guess that would belong to the B&W G3?
Yes, that one was to go with the B&W G3. The older model had DB-15 and ADB. The third blue Studio display is the least common. It's more black than blue. It was updated to have DVI and USB instead of ADB. It had an integrated USB port that was where the RCA video input was on the previous two models.

That sucks man (the logicboard)!

Are you going to replace it?
Probably not. It needs alot of work. I pulled the heatsink off and all I saw was burnt original paste. Okay that solves the freezing issue.

It wouldn't start with the door closed and half the RAM doesn't show up. Reseating the RAM every start fixes it but unless you close the door ever so slowly it cuts out. I think it is a ground problem in the PSU snake to the 24 pin connector on the Logic Board. For a single 1.25 MDD I don't deem ordering parts worth it, especially since my daily driver is a G5 and a MBP.
