Excellent write up. I’ve looked for a good picture of the atx adapter on numerous sites and yours is by far the best. Thank you so very much!

@Shahram Alavi: It seems as though a swap might be feasible. The only pins I’m not sure about are the +3.6v pins. The ATX +3.3v ones might suffice, but I’d have to try it to be sure.

Your best bet might be to find a replacement IBM supply on eBay — it’s amazing how many old parts you can find there.

Hope that helps :)

I am glad to hear that my own experiments and information helped you to get your machine running again, have a good day.

P.S., thanks for the link to my site.

Just what I’ve been looking for. I’ve just purchased an old 400 mhz Strawberry for what equals around 35 $ with a fine startup chime and no dislplay – with the intend to do an ATX conversion, still making it as small as possible (and a friend of my has an ols LC III lying around) So this could be the answer.

Kind regards
Morten

This machine is now slot loading, thanks to the DVD-ROM and floppy slot widening. It should be possible to do almost the exact same thing with a true slot-loading iMac.

This is awesome. Has anyone done it with a slot load machine yet? I have like three of these sitting around gathering dust and the only thing is that the power supply is dead.
