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…

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…

Impressions on speed and battery life. Speed: There are broadly comparable start-up times; the system, however, seems marginally slower in saving a file for some reason, but not …

I just love my iBook SE (366 Clamshell). however, the battery seems to be completly dead. The iBook was running OS X, so i installed Mac OS 9 to run the Battery Reset application…

Great! Love to hear your impressions on speed, battery life, etc

Following repeat problems, I replaced the ram chip, and now there is no trouble with Virtual Memory enabled or off. Ram must have been bad, though the particular component has give…

Driverguru, the "Nike" you're describing was a shipping product from not that long ago. It was an add-on to the iPod, not a custom MacOS portable device. And "Nike" wasn't a code…

On the other hand, what is it with beige motherboards dying? I replaced the one in mine twice over the years. Both times the symptoms were a non-booting OS X install, OS 9 bootin…

Thank, Frank. That should be easy to find. On the other hand, what is it with beige motherboards dying? I replaced the one in mine twice over the years. Both times the symptoms…
