I have a Macintosh IIci, running 7.6 with a special Mac to VGA adapter so I can use it on MultiSync (modern) screens. The Mac starts up fine but after about 5-10 minutes the Mac turns itself off, when you turn it on again in a half a minute the machine turns off. Then if you try and turn it on again it will only be on for a few moments. I'm guessing I need a new power supply. I just want to confirm this before I buy anything.

Thanks in advance! :cool:

Not sure if this will help, but will offer anyway.. I have a complete machine (boots fine) IIci. How about $15 + shipping? (USPS)

Thanks for the offer but I don't know. I have over 35 old Macs, I don't need to buy anymore, my machine works fine but I believe the power supply is going or is by now dead. I can get a power supply for $8 on eBay with $12 shipping though, or I can find them similarly priced around the web. But just for the heck of it (or if I change my mind) what are the specs of your machine? Mine are below. I also have a Macintosh IIcx, I can see if that power supply works in the IIci (which it should) but I dunno if that one is dead also.

Macintosh IIci's Specs:
Raster Ops TrueColor Nubus Card
Numbus Ethernet Card
Macintosh IIci Cache Card
12mb RAM (or more I forget)
500mb HD - OS 7.6

Well if its slow to boot or shut down, it seems like an OS the Mac II's had issues on some of that... If no power till then a Logic Board, PS, Ram (prably not but who knows:))...

Sorry I couldn't understand that too well.

I'll try and reset the PRAM tomorrow, I believe it is the power supply. I mean why else would the Mac just shut off when your in the middle of something (not always the same activity)...

I'll start shopping for one, or maybe does anyone have a Power Supply for a IIcx/IIci/Quadra 700 (which seem to be all the same), a complete computer is nice but I don't know,........maybe.

:confused:

Try eBay or a computer store that sells second hand Mac parts.

And here's the service manual that shows you how to replace and install the IIci/Q700 PSU:

Thanks! I forgot that I'd probably have to figure out how to move things around and take things apart. I see that the Power Supplies are only $7-9 but the shipping is usually $10-12, so Looks like I'll have to pay around $20 for one of them...meh

keep the replies commin'! :D

Well, I really would try simply things before wasting money on a new PS... But if you do be sure to get on in a Apple Service Part Box or Seal stright from Apple... So that way there no problems...

Too bad a power supply from 1988 is pretty hard to find brand new in a box at one of the new Apple Stores, hehe. :rolleyes:

I found one on eBay from a seller I have bought items from before. If I can't find a better deal I'll just buy it there. Ye Old Mac Milt saves the day again! :eek: :)

The one that is here is a basic stock system. I believe 64 mb ram (might be 128, would have to fire up), 80mb drive and good floppy.

Case is overall in excellent condition, I think one or two of the simm socket clips are bent / broken, but it still hold the memory in place.

I would just prefer to sell the whole thing, but if you want only the PSU, I suppose we can work something out.

Not available today on AIM / Aol but will open it up tonight / this weekend and we can chat.

I can not help the originator of the thread, except to say that unless this machine in particular is of some special value, I'd just ditch it or buy the replacement offered here for $15. I mean, you're not completely sure that the $5 more you'll spend for the PS is going to fix the problem anyway.

On a more general note, I got an old IIcx which hasn't been booted up since I got my B&W G3 in mid-1999. I've been holding on to it for nostalgic reasons, but when I saw Sonnet's 040 upgrade cards for earlier Macs, one that would help this bad boy run 8.6, I began to think that maybe this old fella old get some more use. Although for what, I'm not sure. Just a geeky project I guess. But I really liked 8.6, and I may find some uses for it that would take up too much time on my less-ancient B&W. (God knows I'd love to get a new G5, but financial realities are keeping that from happening.)

There is also the possibility that it is the logic board - the IIci is a soft-power model, meaning that the logic board contains the on/off switch logic for the power supply (this is also why you can use the power key on the keyboard to turn the computer on and off).

The power supply is really easy to replace - you just open the cover and pull out the supply (I think there is a plastic clip to release, but that's about it, not even any screws (except the one for the cover, if it's even installed)) - then just slide in the new one.
