Hmm I've found quite a few I have some machines that did explode already. This is my first macintosh II not sure if I'll keep it or not but I want to play with it at least first and I couldn't wait to get those batteries out when I saw them.Wow, that was close!
Sidenote: Why is it that some people seem to only find Maxells, and some almost never find them? Was it regional? In probably the 30+ Macs I've come across, I have only found one intact one...
Forgot the edit was removed, so ill reply. Meant to say ive only ever found one maxell.Wow, that was close!

Ohhh hmm nope, I have some batteries, but didn't put them in this is my first macintosh II that I've played with so I was not aware that they required the batteries to boot. On machines I've used in the past that required it, they would usually power on but just not boot, this isn't doing anything at all.Have you got a pair of brand new batteries ? The Macintosh II series will need ones to kick the boot process (there's a trick shorting two wires on the PSU connector though)
Just put fresh batteries in it but still nothing so unfortunately that wasn't my issue.Ohhh hmm nope, I have some batteries, but didn't put them in this is my first macintosh II that I've played with so I was not aware that they required the batteries to boot.

Ugh yeah I was thinking I'd need to do that, I guess I need to find a list of caps to order or sit and look them all up on my own but rather just order them and have them on hand before disassembling.Your board has the original electrolytic SMD capacitors, it needs to be recapped.
These Mac IIs also have a tendency of problems with their start-up circuit which is documented here: https://www.downtowndougbrown.com/2015/03/explanation-of-the-macintosh-iiiix-power-onoff-circuit/
My Mac II wouldn't start even after it was recapped because of a bad trace in the start-up circuit.
Got it I'll give that a try when my caps come in. On another note what's the easiest way to tell if this board is FDHD already? I couldn't seem to find a list of the chip numbers just which chips needed to be changed.That one just pulls up by hand, it’s inserted directly into the CPU and MMU sockets. Just be gentle with it.

I get what you mean. I've never seen one, and I've collected a lot of machines over the years in NW US and UK.Wow, that was close!
