Posted by davelawrence8 at 11:51 am on March 17th, 2021. Up next for #MARCHintosh: Syncing up my Newton MessagePad and eMate. Magic.Īnd here the PowerMac sits, two weeks after I took it out of storage, still humming along and plugged in – mostly because I’m nervous to shut it down again. What were the exact steps that worked last time? Let’s try that.Īnother PRAM zap, and while the Mac hangs on boot, hit the reset button again. A dash of cuda resets, a pinch of removing the PRAM battery, invoking the Command-Option-P-R incantation – I went through a week’s worth of this witchcraft, trying in vain to get that Mac OS 8 boot screen again. I tried these techniques over and over again, in a variety of steps, like conducting some ancient spell. I found a few tips online about disconnecting the motherboard to reset the power supply, performing a hard reset to the motherboard, and letting the PowerMac sit in a time out and think about what its done (okay, that one’s mine). i would say this is a first, but ive had this happen before about a month ago with the exact same issue (since then hard-drive was erased and restarted from scratch) I. The PowerMac would not boot back into the OS, even after zapping the PRAM, performing a variety of key commands on startup, and multiple restarts. I ran a quick first-aid with disk utility today but unfortunately the disk utility froze on 'preforming fsckapfs -n -l -x /dev/rdisk1s1'. Since the Mac booted into the OS, I figured a fresh restart would be a smart idea. Great! We’re in business! I let the PowerMac boot into OS 8.6, and started a Disk First Aid routine to make sure everything in the hard drive was working properly. That one’s out! After a few more tries, I found one RAM stick that let the Mac start the bootup process. I started with the lowest memory RAM stick, and after trying to boot, got the familiar “ bad RAM” beep. Time to troubleshoot.įirst thing’s first: start with one stick of RAM and see if that works.

Install the software and run any needed updates.
Select the option to do a clean system installation. Launch the system software installer, then press Cmd -Shift-k. On the underside of the motherboard, directly under the batter, some of the solder dots seem to have flattened. Insert the first system installation disk or the system installation CD in the appropriate drive, then restart your computer. I used tin foil to try and seat the batter correctly.
I cleaned it up, but the + connector on the batter socket was snapped. I looked inside and the battery and socket were fried. However, when I press the reset/interrupt, it gives the error code: The screen seems okay it boots to a blank white screen.
