No programmer unfortunately, so will continue to attempt the revive. Followed all of the above - drive is on side, oil in motor, heated gently. After an hour or so, booted with drive on side. The motor turns just fine it seems, but now it starts with a solid orange light and one-two clicks...

Thanks I'll give it some sewing machine oil and report back - have got synthetic 5W30 but it feels a bit wrong! @Franklinstein that's exactly what it is! Heaving and groaning something awful, it is. How would one consider dumping the PROM?

Thorough search for attempt to revive - seems like it's a good idea to oil the motor? Can lithium grease be used? Or should it be a machine oil? Exactly where should it be put and what needs to be rotated? Does the drive need recapping? Have circled the obvious ones with excellent mspaint -...

Update to this. Many hours of dipping & sanding later and it's pitted & macabre. However, all of the rust is gone, even though some of it was probably structural. It'll be fun to put back in and hopefully boot up safely. Will post update pics later.

Thanks all. It has been indeed a pretty lucky battery bomb. Have taken it fully apart and begun slowly removing the rust with a wire brush - it ain't fun. Here are some "before" detail pics: It'll be sanded and wire brushed, will run some phosphoric acid over it, and then perhaps a...

That certainly took longer than expected. The case was frozen in place by the battery bomb, and took hours to separate without damaging it. Perhaps by serendipity (must've stored it laid flat, on its ... right? side) - the battery bomb appears to have popped onto the metal but spared most of...

Thanks - will give it a go and report back.

Hi everyone Have had this Classic for 20+ years but haven't really looked at it since last boot in 2005 or so - forgot it existed. Sadly, the pic is from AFTER cleaning it with distilled water. It looks bad. Have refurbished a fair few Classics since, but am a bit confused about this one - if...

Ha ha, indeed, thanks for your perspective. Personally love all of the AIOs right up to when everything became aluminium-finish. It seems though, for some reason, these particular models aren't as well-regarded, which is strange as they have lovely high refresh Trinitron displays and some are OS...

Have been using one of the "can boot to OS 9" eMacs as an early OSX machine, however the front panel is yellowed as anything. Not looking for a philosphical debate on the technique. I would like to restore the original look. More looking for whether it's possible on these double plastics. Has...

That doesn't sound ideal. Alright, will power it on in a dark room - could it be due to the shielding below the AB (which was pretty rusty, & bent out of shape a little when reinstalling it)? Alternatively, can a 580CD AB + CRT fit in the same spot? Got one that the case exploded into showers...

So, recapped the 6300 board and plugged it in - chimes and boots to ? screen. Next step is to do the same with the 580CD board and see how it goes. Guessing this is now the world's slowest PM 5500! There were a couple of alarming "snap" or "crack" sounds from the back of the CRT that lessened...

OK, so thanks again to all - cleaning up the posts on the AB and removing the gunk from the connectors did the trick. @joshc Everything appears to work, however now on power-on there appears to be a hissing/whining, almost sounds like a kettle. Sounds like it's coming from the back, near the...

So, measured top 3rd pin from the edge with 1 probe, and touched other to 4 & 5 (both black wires in the above photo). Repeated the same on the bottom, 0L. Changed ohms to 200, 20k, etc, no difference. Did the same on a spare Performa 580CD board, and same results. Assuming I'm doing it...

Ok! And more newbie questions - does it have to be plugged into the PSU to check this? Or can it be done with the board out? I put the red probe where you have GND marked, and the black probe on the pins adjacent to it (and 2 across - both black ones). Getting 0L. Swapped red for black, and...
