Now that I have a bunch of fresh PRAM batteries, I can try put in new batteries and determine whether it's a hardware problem or just dead PRAM batteries.

There are quite a few older Macs that won't even boot with a dead PRAM battery - I discovered a few weeks ago that every Mac II, IIx, IIcx, and IIfx that I own would not boot. A small thing, but a lot easier than unplugging the AC cord. Now that I've installed new batteries, I can shut down the MDD and then start it up with the power button again. For instance, the Mirror Drive Door Power Mac will shut down just fine with a dead PRAM battery, but it will only start up again if you unplug the power cord.

It's really nice how Mac OS X can automatically log into Apple's time server to set the system time at startup. when the computer is powered down) for quite some time now.

I've been running my G4 Power Macs with dead PRAM batteries (they keep track of the time, boot drive, etc. If you know more about G5 hardware, please tell me more. While a 2.0 GHz or 2.3 GHz Power Mac G5 would benefit from twin dual-core CPUs, I suspect that would be the only benefit of such a transplant. My gut feeling is that it would run at the same clock speed as the CPU that the Power Mac was designed for, although I have no hardware knowledge to back that up. Then there's the question of whether it would run at 2.5 GHz.

Assuming the 2.5 GHz CPUs were running at full speed, this bottleneck would make the upgraded machine slower than a true 2.5 GHz dual-core Power Mac G5. My guess is that while it may be possible to swap this CPU into a slower (2.0 or 2.3 GHz) Power Mac G5, the memory bus would not run any faster. The G5 Power Macs were all designed so that the memory bus ran at one-third (in some low-end models) or one-half of CPU speed, and the last generation dual-core Power Macs had a different architecture than previous G5 Power Macs. It seems someone had a 2.5 GHz dual-core G5 module for sale on eBay.

I received an email wondering whether it's possible to upgrade the CPU in a Power Mac G5. It was also a good opportunity to reaquaint myself with some of my favorite old Macs. than I did actually copying files from the floppy disks. And without an Ethernet network in the basement, the PowerBook was a great machine for moving the files to my office.ДЄll in all, I spent more time setting up old Macs, finding cables, etc. It's been a long time since I've worked with 800K disks that wouldn't mount on a more modern Mac, and it was great having an old SE that could read the disks - which included the client's Masters thesis. Step 7: Pop in a blank CD-R disc, drag the copied folders to it, and burn the disc. Step 6: Bring the WallStreet upstairs, connect it to our Ethernet network, reboot into OS X 10.2.8, enable File Sharing, mount the Work partition from my G4 Power Mac running OS X 10.4 'Tiger', and copy the folder to its Work partition. I am a firm believer in keeping all of my work on a separate hard drive partition. Step 5: Using the same cable and process, copy the files to the 'Work' partition on the PowerBook (booted in Mac OS 9.2.2).

Enable AppleTalk networking, turn on file sharing, and copy the files to the folder on the Power Mac. Step 4: Find an ImageWriter II printer cable and connect it between the printer ports on the Power Mac and the SE. The SE was able to mount and copy the 4 disks that the newer Macs couldn't even mount! Step 3: Dig out the old Macintosh SE, one of very few Macs I own with a built-in 800K floppy drive.

No luck with the 800K disks in Mac OS 9.2.2. Step 2: Pop the floppy drive module in my WallStreet PowerBook, which I always keep handy. If not, set it aside to try on another Mac. Step 1: Set up the old beige Power Mac G3 (giving it a fresh PRAM battery and installing a working hard drive with Mac OS 9.1). My Mac collection is in a storage room in the basement, and I have a desk set up outside the room for work. Some of these files go back to the late 1980s, and there was always the risk that some disks might be unreadable. I worked on a challenging project over the past week, copying files from a handful of 800K and 1.4M floppies and burning them to CD.
