Great.  Count me in for 1 set (4 modules).  I was thinking of getting 128MB but I think that's probably a little over the top (though it would be cool to look at "About this Macintosh" and give myself a satisfying nod  :-)  )

Hi would you ship to the UK?  I am interested too

Yeah, I've fixed it.  It turned out to be the RTC chip. I checked the NMI and it was all fine so that was not the problem.  Then I searched the forum and found someone who had the exactly same issue as me last year, albeit with Q700.  Battery leak damage, startup chime is fine and then the...

Thanks @techknight.  Yes the online resources tell me 0000000F is software related, which confused me.  But maybe NMI is being triggered somewhere, causing this error code to appear.  I will check the NMI area carefully (which I haven't done yet apart from adding R11). At this stage, I am...

Thank you @techknight for your reply. The first photo was just to show what the board looked like when I got it.  As part of repair, I cleaned up the area and added all of the missing components including R11.  I don't believe NMI button is stuck because if I press it before the screen comes...

Hi I bought a non-working Mac IIfx from eBay.  There was a battery leak damage to the motherboard.  Some components near the start up circuit were missing and many traces and vias damaged.  The SRAM at UD16 had a couple of pins corroded away as well.  Not surprisingly, initially it didn't boot...

Yeah I did think about just cleaning underneath and soldering the chips back, but I couldn't be bothered doing it twice if it didn't work.  I had already ordered the chips (they only came in lots of 20s so I have plenty of them anyway) so I just replaced them to save the hassle. Now IIci is...

I am answering back to my own question.  I fixed the shutdown issue with my IIci by replacing three chips in the startup/shutdown circuit (UB13, UD13, UE13).  It is working perfectly.  I do not get the shutdown delay that Jon183 reported. You can see the photo of the motherboard with chips...

I finally got around to looking at this again (only after 9 months :-)  ).  I've fixed the issue.  I am posting my result for anyone who is having the same issue. I checked all traces and vias using the IIci startup/shutdown circuit schematic.  I found no issues. In the end, the only thing...

Hi Jon183, it's been a while since you posted this so this is a long shot but I thought I'd give it a try. I have a similar issue to you.  I dug up my 30 year old Mac IIci and it didn't boot properly (It started up a couple of times, no sound, and then eventually it stopped booting completely)...

Hi all, I got my 30 year old IIci from my parents' place a couple of weeks ago.  It had not been switched on for over 20 years. It did power on but there was no sound.  But eventually it stopped powering on as well after a day or so. I looked at the board and not surprisingly the surface...
