Nice find! I'm sorry to hear about the corrosion, though. It might be repairable, but in the worst case, if you need a new logic board, I think like 360alaska said, you can get on…

That's the button, If you end up needing a logic board I believe there are a few that will swap in... Also, is that a G3 cache slot accelerator? those are pretty rare!

ok - have to have a go at this thing so - is it true that acetone neutralizes the acid decay? - plan on talking out the board and washing the bejasus out of it with acetone - …

I don't think the TAM is impossible to fix. But I bet the back of the board is a mess.

ah jasus nooooooooooooooo - looking at those pictures I can see green on all the via's under where the battery was - noooooooooooooooooooooooooooooooooooooooooo

hi 360 alaska took a few pics of the mainboard is the reset button the one outlined with the white line Got a bad scare when I first looked inside this....the harddrive was half…

Congrats on your TAM find Of course it will probably need caps...Did you try the reset button on the logic board?

what a score................I got me a TAM baby!!!!!!!!!!!!!!!!!!!...............Oh happy day - The tam is not working..........I know nothing about them. - took off back cover…

oh.........here is the other yoke I picked up ------------- .....................

Too bad you "HAD" that 5300, Bibilit. Not only is there problems with the power connection on the 190/5300 but sometimes when the battery leaks, the PSU Area (under the trackpad) i…

yup the HDD is bad. Sometimes if you flip it around, itll get going temporarily.  I just picked up an SE and its doing the same thing. Had to rotate the drive around so i can get …

I have nowt (a Yorkshire term meaning nothing) in the way of Mac laptops except some Intel ones (MagSafe, various versions) and an iBook G3 (Snow, Dual USB, 700MHz, 16MB VRAM, 256M…

It is not advisable to use ceramic capacitors in DC-DC switching circuits to replace electrolytics. Tantalum is ok.  Ceramics will vary their capacitance based on the applied volt…

I'm just shaking my head on this because looking at the 190 power area on the last pict Sherry H. posted and having seeing it on my 190, that is a tiny area to recap. No way one is…

the flub-flub-flub is not a broken trace. its either a bad capacitor, shorted capacitor, or shorted load somewhere on one of the rails. You will need to measure resistances to grou…

Yep, DC-DC board is specific to the PowerBook 5300... Unfortunately the 190 has got the power circuitry directly on the logic board. I'm not sure what could be wrong there except m…

Tonights job...

Test the adapter on another machine, like the clamshell iBook if you got it. At least you will know that will work or not.

Thanks to everyone for support. I will have a closer look, and hope to find something. I have checked with hard drive disconnected, without VRam and Ram.
