Any chance of getting a scan of that manual?

That makes me feel better that a “coincidence” was possible. I just realised I had also been stressing the PSU out earlier with a new SSD-IDE drive copying off the original ATA hard drive. Maybe a combination of both sucked a little too much for it to handle.

That was my original question in the thread. I had come to the same conclusion, how could RAM with higher voltage break something rather than it just not work? The only answer was that is was coincidence that the PSU blew at the same time I opened the machine to put the RAM in.

Exactly what I thought and then even with removing the EAM the PSU is still smoking. They system definitely doesn’t like it as the power light comes of for about 3 seconds and then turns off the whole the system still tries to boot with PSU smoking it’s head off.

No. The ram fitted fine. However when I checked after the “incident” the ones I installed were 5v instead of 3.3v

I found another G4 in my collection with a lot more RAM than the one I was trying to upgrade anyway. So I might just out this one on the “maybe later” shelf.

I have a few 4400/7220s as well as a StarMax 3000. I want to be able to use one of them to burn CDs. I have an ATAPI CD-RW drive in a currently dead G4 Gigabit. My other option is a 6500 I have but that is a bit more fiddly to swap out the optical drive. Can any of these be used to burn CDs?

I have a G4 Gigabit Ethernet and accidentally put 5v RAM into two of the slots. It booted however the power light went off after about 3 seconds and then I could smell smoke coming out of the PSU. I unplugged it, removed the RAM and rebooted. Same thing, Power light goes out after 3 seconds and...

I will take one of these sets for sure if they are available. Craig

This is correct, the Pioneer LX100 is the only legit 68k clone. Pioneer installed LC/Quadra 630 logic boards in them with no mods. All mac diagnostic software sees it as a genuine 630.

Mines has an SE rom which only supported 800K. How could the Outbound support 1.44M?

Is this the card that Daystar developer for Apple and they both sold it with different logos?

What do I have here? This looks like it might be an 040 to PPC upgrade card yet it doesn’t have any identifying marks on it. If that is what it is what models was it intended for, LC474, Quadra 650?

Battery removed long ago and board thoroughly cleaned.

The rest of my logicboard is fine as well. Just this connector. Something weird us going on to cause such isolated corrosion.

After getting the tip regarding the GIMO port loopback decided to dig a little deeper and have found the issue.😢 After cleaning it still oddest work. I think the socket itself is stuffed. I will transfer the whole DOS setup over to another LC630 I have and see if I can get the loopback board...

System 7.5.3 Update 2 and the loopback cable is installed.

I have a Reply card but haven’t attempted to install it yet. I am still having problems getting my Apple DOs cards to work. What is the Vibra module?

I have been trying to get the DOS side of my LC630 going. I have the PC Set control panel set and it sees the DOS card. When I restart the card I get the startup beep. However when I switch to the DOS side there is no video. I have tried fixed resolution monitors and multi scan monitors but I...

From my experience you also need to choose the slowest write speed you can. I find any disc written above 4x rarely works when I try it in an old Mac. My current Mac Studio with Apple external SuperDrive doesn’t give me a speed option (it is greyed out at “Maximum” which is about 20x). Most...
