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

Man, I never really knew I needed this until now. Would be cool to have one to cover the floppy slot actually.

You have a 3D printer? Nice. I don't know of a 3D model of the drive cover, but if someone has an SE drive cover and a 3D scanner, they could scan it in.

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.

If you didn't bridge anything then you might have a small fragment of debris floating around... Take that board out and shake it or blow some air on it... Also, Have you checked wi…

Well since pretty much everything on the entire board runs on 5 V . Usually shorts are caused by solder bridges. But in the case of these LC boards. Have a closer look at all t…

I am thinking that maybe the board is bad, the problem come and goes for whatever reason, i have removed most of my work to double check, and nothing obvious. The problem disappea…

As a general rule of thumb, any 601-based PowerMac I use OS8, 8.5/8.6 on 603-based machines and 9.1 on 604-machines... that being said I am running 9.2 on my 9600 with OS9helper. G…

I havé continuity between 5 volt and ground at the PSU connector and at C19 pads.

nothing too significant.
