someone gave me a couple of miniature pc's today
they were P-III's but missing the proprietary powersupplies.

never saw anything like it...the power connector was
just 6 pins.

the only marking was the model number BK630.

a minute on google and I found it was called an iBook

and I even found power supplies...but they were $80 each!


Well so much for that project...

except the specs said they were 5volt and 12v
(no other volatges were listed)

on the mobo was a header for the HD power jumper wire...

what the heck , I;ve got nothing to loose...
just plug in a standard AT power supply there
and run the HD & floppy direct from the PSU


well guess what...both machines worked!

on one of them the ps/2 ports were bad...but the
machine works with a USB K.B.

Of course they will look a bit funny with an AT powersupply
bolted to the top :)

IIRC, there were "BookPC", Apple would throw a fit if they
knew you're calling it an iBook.

They were a bastard child of PCChips/PC100/ECS. Cute little
things for their era but pretty junky overall.

The worst part is those PSU had quite high failure rates,
probably why yours are already missing the PSU.

I wouldn't worry about it, funny but working beats broken.
Another alternative is to get a PSU that has a voltage
adjustment pot (to make it easier, instead of trying to mod
the supply to boost the output some) then run some heavy
wires from it to make it a brick-like supply lying a bit
further away. Using the pot you can adjust so the voltage
reaching the motherboard connector is closer to 5.0V under
full load.

Well, I think I'm going to scrap the board with the bad ps/2 ports...
but I put the other board in an ATX case

and was able to actually use one of those proprietory , Dell, ATX power
supplies
that has been sitting under my bench for ages.
Since I do not need to use the power connector...
I figured it's a good way to get some use out of it...

It some day I do get a Dell machine in here that needs one of those
power-supplies...
I still have a couple left anyway :)
