    Power Mac 7600 PSU clicks but doesn't start up

    I just acquired a Power Mac 7600/120 and it seems to have a power issue, but I'm not entirely sure what the issue is. When you press the power switch on the motherboard, the power LED lights up green for just a second and there's a click from the power supply, but the system doesn't start up...

    Affordable graphics card upgrade options for G4 Cube

    I'd like to upgrade my G4 Cube's graphics a bit but I don't really want to spend $100+ on a video card. What are some good affordable options? Was there ever a Mac Edition Radeon 9200 AGP card that could fit in the Cube, or a GeForce 4 MX440/460?

    Evie's Conquests

    Somehow my recent-ish Conquests thread vanished so I have to start over again...I've gotten a couple Mac things recently but one I only just got today and the other hasn't actually arrived so I'll start with this one, a PowerBook 180 with a 6MB RAM upgrade I got off eBay to replace the 180 I...

    What kind of cord does a SCSI Zip drive need?

    I recently acquired a SCSI Zip drive from a thrift store, but it didn't come with either its power or data cables. The power cable should be easy enough to replace, but what kind of data cable do I need? Would a straight-through DB25 to DB25 parallel cable work?

    iMac G4: No screen activity

    I picked up a 1.25GHz 17 inch iMac G4 at VCF East this weekend but despite being in very nice shape overall, it seems to be troubled. When you press the power button it bongs like normal and the internal fan spins, but the screen never comes on. I've already tried pulling the RAM (it was already...

    CPU upgrades for PowerCenter?

    I have a Power Computing PowerCenter 150, and I also have an Apple 200MHz 604e CPU card. Could I put the 200MHz card in the PowerCenter, or does it require only PowerComputing CPU cards for some reason? And if it can accept an Apple CPU card, can you freely upgrade from 604 to 604e or am I stuck...

    iMac G5 Doesn't Recognize Any RAM

    I have an iMac G5 (2.1GHz iSight model) I rescued from a certain death by replacing the power supply. It's working in the sense that it powers on and I was able to install an OS, but any RAM stick I've tried to put in the RAM slot so far is not recognized, the computer only ever reports the...

    iBook Clamshell Screen Replacement Advice

    I've got an iBook Clamshell (graphite 466MHz FireWire) with a bad screen and I was able to buy a screen that is supposed to work (it's a LG Phillips LP121X04). I don't actually know what brand the current broken screen is. What else do I need to prepare for this? The old guide I found says you...

    How to open up a 7100?

    I've never owned any of the machines in the IIvx case before and now I have a 7100/80. Unfortunately my hard drive seems to be bad, and I don't really know how to open the machine up beyond sliding off the top cover. How does it work?

    G4 MDD main PSU connector pinout

    I have a G4 MDD (single 1.25GHz FW400) that doesn't power on, which I'm sure means a dead PSU. I managed to find a spare but I don't know if the spare works. What is the pinout of the main motherboard power connector so I can probe it and see if it's putting out anything?

    Broken icons in dock in Tiger?

    So I got an eMac the other day with OS X 10.4.11 and it's fully functional except for the fact that most of the icons in the dock are ? icons that are non-functional. How exactly would I go about fixing this? This hard drive is packed with software and I don't currently have a way to back it...

    Color Classic doesn't boot off external HD

    I somehow messed up the boot partition on my SCSI2SD in my Color Classic and made it unbootable, so I figured I'd just use my external SCSI HDD with System 7.1 (and the required enabler) installed to boot the Color Classic and re-bless the system folder or whatever else I'd need to do to restore...

    No sound from Color Classic

    My Color Classic (upgraded with a 550 board) no longer bongs when booted up. I haven't recapped the 550 board so could it be caps that are the cause?

    Mac IIfx outputs green video

    I have a Macintosh IIfx with a Macintosh High-Resolution Video Card (supports 640x480 at 67Hz) and when running it through a 10-switch DB15 to VGA adapter set up in 13" RGB mode, I get green video. And by green I mean...really green. I'm using one of these adapters set for 13" RGB, mode 5...

    Problem with Power Mac floppy drive

    I needed to make floppy disks for one of my 68k Macs so I decided to try using my 9600 to do it. However, despite using 6 disks from 3 different brands, I wasn't able to initialize a disk successfully. I'm hoping it's just dirty. If it is, how do I disassemble it to clean it?

    Diagnosing the 9600 From Hell(tm)

    So I've had this Power Mac 9600 for at least two years now that has just never worked. It just will not boot off a disk. My 8.1 and 8.6 CDs don't do anything at all (and this is after I cleaned the current optical drive and upped the voltage a little) and while it attempts to boot off my 7.6.1...

    Replacing a Power Mac G5 Optical Drive

    I'm thinking my Power Mac G5 optical drive has gone bad, as it's experienced great difficulty just reading CDs/DVDs and won't burn them at all, even at a reduced speed. Do I need to be overly specific when looking for a replacement or will any SATA DVD burner do after taking the front panel and...

    Diagnosing a Plus that won't turn on

    I have a Plus (that was converted from a 128k) that doesn't power on at all. Where can I probe with my multimeter to see if the power supply is putting out any voltage?

    Mac Plus floppy drive jammed shut?

    I just picked up a Mac Plus that works, but the floppy drive seems to be jammed in the down position despite there not being a disk loaded. Is this something I could fix just by cleaning and lubricating the drive or is this a more serious issue?
