So have you tried bridging the two pins? Have some random Combo drive in my Pismo (from a Dell Pentium 4 notebook), did the same mod and it works a treat booting now. The Pismo s…

Thanks for all your help in solving my problem, I will probably just buy a replacement from a local vintage computer supplier this weekend. thanks again

Until you can find a replacement PSU or work out how to fix your existing one, I think you should look for a simple swap. The Apple II FAQ (easily found on the net) describes the …

it still pulls only 5 and 2 though.

As long as the mac is plugged in I'd should be ok.

3.6-V primary cells such as the half-AA lithium thionyl chloride battery used for PRAM maintenance and time-keeping in Macs rarely leak, even after declining to voltages such as 0.…

You want to measure voltages with the power supply plugged into the motherboard. I believe it needs a load to function properly. Mike

Well I did what II2II suggested and took a multimeter to the power supply. First off idk if this is another symptom, but when the system board is unplugged from the psu, and u turn…

Ok, thanks, once I get back from our camping trip I'll open up the iMac and see if there's a dead battery. -Apostrophe

My 2E used to overheat on hot summer nights, and when it did, it would behave very strangely. That's why clip-on cooling fans were a very popular accessory. And for years, someone …

I don't think there's any difference between a dead battery and no battery in an iMac, it should still boot. It's the same 3.6 v battery that they've been using forever, so luckil…

Hi, I'm in a good mood; today me and my dad were over at the house we're trying to sell, to clean up the yard and stuff. While there, I picked up our hp Photosmart printer. I br…

I'm more inclined to say the PSU is the problem, probably because my II+ was exhibiting similar problems and swapping in a modified AT PSU solved most of the problems. The quickes…

Easy causes could be loose chips (give a solid push with your thumb on any socketed ones) or a marginal power supply (try with no cards (especially the disk drive card) installed).…

Yes, it did cross my mind when you joined up. The other macdan is a bit of a Powerbook guru. In fact, he might have just given me the clue I need to make the UJ-841 drive bootabl…

Well I bought a Monitor II, Apple IIe, Disk II, Parallel Pro Card, 80 column card, etc. It was complete in all the boxes, with manuals and disks, and extra parts with only little u…

MacDan says they'll take any standard laptop optical drive [] ]'> Click to expand... Well, that's a coincidence in names!

The wheel turns ever slow, and yet it doth turn... I'm typing this on the Lombard right now. It's got OS X 10.2.8, 512MB of RAM, the original 333 CPU and logic, a new 80GB 5400rp…

I'd go with a firmware update. Its unlikely that OS X would have anything to do with it - despite the fact that I primarily run my iMac under Mac OS X, it will quite happily boot o…

You might be able to instal directly in Open Firmware.

Might be a firmware update, yeah.

Good news: I got a hold of ROM 2.5.1, on an installation CD for a G4 system. [] ]'> Bad news: The CD won't boot my G4! [xx(] ]'> According to the system profile…

I have a USB2 PCMCIA card that I can use if that particular change is made.

For my Lombard I just pulled 5v from the pads on the bottom of the mobo from the USB ports. They are nice and exposed and it is super easy. I have never used much more than a keybo…
