Which reminds me..one of these days I've gotta find a Rev. A iMac somewhere...would be a neat machine to play around with, not to mention that if I keep it original and in good nic…

I am 99.99% certain these hacks will only work on a 233Mhz Rev A board.

From what I gather, 8.6 is the minimum that will run on this iMac, and you say it would need less than 8.6. Does that mean there's no way to get this to work?

My B&W gave me fits until I did a firmware update on it. I went from 8.6 to 9.2 to 10.4 http://discussions.apple.com/thread.jspa?messageID=3841731 The Revision 1 B&a…

^^digging around it looks like the floppy port will only run on systems below 8.6, if the iMac has had the firmware update applied for OS X then that too could be a factor.

Yeah, that's what I'm thinking of. I do hope it's the RAM, will try with some from my G4 later. Fucks me right off too, as I scrounged this last week and there was another where I…

Yep, booted into OS 9 and the drive didn't do much except spin and then stop. I also tried inserting a disk before booting and nothing much happened. You would think it would spi…

^^sounds like a hardware rather then software problem.

I assume you're using OS 9 or earlier to try and read the floppy, being as there's no support in OS X

But then, why not just do a clean install of OS 9 and skirt around the problem? Click to expand... Both my 8.6 and 9.2 CDs that boot my 7500 just fine give the same error, as d…

After playing with the drive for a while, I was unable to get it to actually read a disk. It is getting power because it spins for a moment after a disk is inserted, but it seems …

J12: It was actually a common hack back in the day to mount a 20 pin boxed header here and connect a surplus Mac floppy drive to it - worked out cheaper than buying a USB FDD, if y…

I just mounted a connector onto the floppy drive port and tried it. The drive is getting power, it spins when you insert a disk.

I have noticed on an old 333 MHz iMac logic board that there are traces for what appear to be: J12 = Mac floppy drive J11 = CD analog audio J4 = Serial port (Used for IrDA in or…

There's a prior listing of offending/offensive ATi extensions in the thread: http://68kmla.org/forums/viewtopic.php?t=822&postdays=0&postorder=asc&start=25…

I've installed OS 9.0 from iMac install media onto a beige G3 and experienced the same problem. The solution was to use the generic 9.0 install CD. You may be able to fix it by twi…

Compare the presently-installed extensions with those that would be installed from the OS 9 CD—using TomeViewer to see the latter if you have to do so—in case what you believe to b…

I have an iBook Clamshell battery if you need one.

Batteryspace.com sells NiMH tabbed 4/3AF cells. Getting eight of them to fit into that tight PB1400 case may be a problem, so the tab soldering must be done in a very compact man…

DON'T put any Clamshell battery parts into the 1400 battery or vice versa. The cells in ALL iBook batteries are Li-Ion cells, whereas the 1400 uses NiMH. Interchanging them would b…

Clamshell battery: With my iBook Clamshell SE's battery being well and truly dead, and since it came second hand with the machine when I bought it (meaning no guarantee or warrant…

first thought, duff RAM/slot, try one memory stick at a time and see what happens or if there is only one then try a different stick. If that doesn't work then I'd suspect a knack…

I recently conquered a beige G3 desktop from university. It's stock + RAM. Unfortunately, I can't get it to boot. Booting from the HD which has OS9 or an OS9 CD bombs after loadin…

Just got a 3400c but haven't dug into one for awhile and haven't opened this one up yet - need a power adapter to test it out before I go taking it apart. Is there a way to tighte…

I have an old edition, (2nd, I think) It's from 1994 and covers the very first Power Macs, so that's where I read it.
