Powerbook 100

[bibilit]

I am the new owner of a Powerbook 100 thanks to Galgot.

For 10 euros he was able to bid and collect it for me while i was in holidays, and the whole sum included post and packing (which was more expensive than the powerbook itself)

The palm rest was broken, the hidden screws were not found by the previous owner, the battery missing, no PSU nor floppy drive.

Galgot was kind enough to give those two last items, both non working, thanks again mate.

The PSU was repaired and Logic Board given new capacitors :



the hard drive was given the "glue in the square hole" treatment, everything was put together again and i fired the little Powerbook tonight:





Most of files are Word or Claris, all where deleted.



the Powerbook is 4 Mb and the Hard drive is 20 Mb, System is 7.01.

The Powerbook is not finished yet, i should reccap the screen, as i had some crashes when the screen started to fade, but not bad at all.

Nice! What does this mean "glue in the square hole" treatment. A common fix for common PB 100 ailment?

 

[bibilit]

Yes, the Hard drive was a non-worker before, both 20 MB and 40 Mb drives have a small hole where the HD arm is resting, filling this hole with hot glue is the fix.

I'm not familiar with this- do you have more info or some links?

Super ! Now we have to find a good palm-rest ( And a left foot for mine...)

@ScutBoy that Connor HD repair trick was posted here by Aplmak :

Was able to repair one for my PB100 like that.

Thanks for the pointer! I don't recall seeing that here.

Congrats! "Hot Glue in the Square Hole..." That is great to know! I will need to research that!

EDIT: I forget - the PB 100 is a 68K or a '030 PB?

 

[Carboy7]

68000, am thinking.

 

[bibilit]

68k (68HC000) is a Macintosh Portable with new clothes indeed.

Now we have to find a good palm-rest 

yes and a rear battery  holder which was also broken, in the other hand i have the rear port latch, so can't complain... the palm rest has been glued back for the time being.

If you want, I now have a PB100 'shell' spare. Its rear battery holder is also broken, but it's just the part that "overlaps", so you'd end up with a small gap when the door is closed.

I'm in the US, though, so shipping would end up being rather high.

Yes, probably, don't worry i will probably find a spare someday locally.

Thanks anyway.

Here is a good map of the caps in the display... I use a little sewing needle and gently lift up the soft screw cover caps so I can put them back on undamaged... Then you need to pop off the center plastic piece before removing the front of the display.. The display plastic slides down.. I usually push from the bottom corners and slide downwards unsnapping the hinge area pieces.. There is a center clip but it usually pops off.. I think it is all explained in the take apart guide from Apple..

There are 8 little 3.3 uf 35v caps disguised as tantalum but really electrolytic canisters in a little black case... wiggle back and fourth and they come off easily.. Don't forget to use a qtip with 90% alcohol and get up all the electrolytic goo.. but don't use too much soaked alcohol as it will seep into the display plastics to the side... so use a DAMP qtip. I have always used small radial tantalums cut very short and layed flat.. it's a delicate job..

BTW I have never repaired a display where those 8 little caps haven't leaked... they leak bad... the solder is a pain in the @#@%( to get flowing as electrolytic fluid has been sitting on it for a while...

Great, i was looking a good picture of the above, thanks.

I want to see the screen's output after you recap it.

Not a huge difference, but caps were shot anyway, not for the faint hearted, caps are tiny are very close one from another.

I am surprised you didnt use SMD ceramic, they would have fit a bit better.
