What kind of monitor is this? Have you tried it on a Composite Monitor? If not, check your VGA Settings. 

I'm very much a fan of the 5400 and even moreso the 5500... There was a lot of machine in them for the money, with a decent video controller as well, and they were actually decentl…

You dont have a 5500/6500 laying around do you? Click to expand... I agree, those are pretty cheap are not really sought after, will try at least for testing purposes.

No, was gone, left while unsoldering. Thanks again

Hearing buzzing matching system functions is the TAM buzz. Means your audio isn't toast, but something is stopping it from producing sound.

If all else fails, sourcing a 6500/300 board, desoldering various connectors to make it fit, etc, would be a good project.  The baking sode mixture sounds like a bad idea IMO, and …

I'd remove the socketed chips, clean contacts and reseat first

I've had a "Mystic" VGA-modded Colour Classic with LC575 board which has been running fine for a decade, and it's one of my most used 68K Macs.  I was also given a "Takky" VGA-modd…

^----  i agree the 5400 is a good machine, its like they finally did it right.

You can find 10" "flatscreen" monitors out there, but you'll have two problems to overcome. The flat screen won't fit the very curvy bezel that housed the very not-flatscreen Sony …

Second vote for the G4-mini and 10" VGA tube (if you can find it). But if you're going to bother making it more modern, why go half way?  Drop a brand new Mac mini in there, or bet…

Somebody done that before (http://www.mac512.com/ccpmg4.htm), back when G4 cube was the smallest Mac available on the market.  However, given that the Cube is such iconic and clas…

Well it increases the current tails in the horizontal output circuitry so it swings the beam harder.  But the problem with this, it adds stress to the sweep circuitry so eventuall…

My main machine is an upgraded Quicksilver G4, which I am using right now. With a 1.6ghz 7447A, a SATA card( with 10000rpm WD's), a Radeon 9000 and an usb card, it can handle youtu…

I thought about this. Can you tell me which one is it? Just so you know, I also replaced the VGC chip and it made no difference. Thanks!! Pitou

Well I cant advise that being a good idea or not...  But, I do know that the trace damage will need patch wires on the ones that are open circuit. 

My guess would be something with the character ROM?

I love the 5400s.

According to Mactracker, the 5400 needs 70ns dimms, and the 5500 needs EDO.  That may be the source of the confusion. Or maybe the overlap in speeds: Mactracker says the 5400 goes …

I would assume that if you put faster RAM in, it will just run at the slower speed if that is all the machine can handle.  But when I used to service PCs, there were always some ma…

Has anyone ever used an LED display for a personal computer display? Anyway, yes the chipset supports it. Just not sure if the Cube with OS X will. Best bet is to simply try.

I think that with RAM speeds, unless you go too fast, you can go faster (but not slower) than the recommended. In fact, it'll make your system faster. Go ahead with 60ns 168-pin DI…

Both are also quite rare (fewer than 150,000 Cubes ever made)...I'm not going to lie; not the biggest fan of FrankenMac-ing the rare ones at this point.

Well, it *is* a challenge after all. 

G4 Cube in Colour Classic? It's funny because both machines have a sort of cult following (in a good way). I'm even thinking of making a Mystic...
