Powerbook 5xx AC Adapter — #5
Ok, so it sounds like my basic idea will work. Good enough for me. I'll try it on the 520 I don't care about just in case.

Mac OS 7.6 on PowerBook 1400cs/166? — #20
The Maxell 650MB CD-Rs came yesterday, as did the floppy drive and HDI-30 to DB-25 SCSI adapter. The PowerBook and the AC adapter are coming Monday (18 May 2015). I found the Clams…

Powerbook 5xx AC Adapter — #3
I havent tried it recently. I vaguely recall screwing around with a generic power supply on a 520 long long ago when mine died. Back when I was actively dicking around with these m…
2400C battery internal configuration? — #6
the lighting is too dark, and the pictures are too blurry to make out anything useful, but its possible the PCB circuitry is similar/same to make heads and tails of my battery.

CPU upgrades and 9600 board faults... — #6
Yeh I'm quite enjoying using it actually... posting this from it in fact. I still havent worked out exactly what it's affliction to the R7k or the properly working Rage128 is yet, …
CPU upgrades and 9600 board faults... — #5
The Sonnet card will work well, and one day look out for one of their later G4 700/800/1000 upgrades which also run well in the 9600, and reliably. It will feel like a new machine…
CPU upgrades and 9600 board faults... — #4
Sounds like all systems are go then. Might do the switcheroo then. Would I be right in assuming the majority of programs wouldn't really be able to make use of the multiprocessi…
CPU upgrades and 9600 board faults... — #3
Never heard of, Sonnet upgrades are usually very forgiving and don't tax the machine like others (with selectable bus, multiplier speeds .... Sonnet did none of that), so I'd go fo…

External port traces run through the internal one first... except for one or two. I forget which.

SE/30 no internal SCSI — #6
that is funny your external port works. but the internal one doesn't. Techknight knows dead scsi traces oh so well.
CPU upgrades and 9600 board faults... — #2
That does not ring any bells for me. Doesn't mean it never existed, but does mean that it must have been pretty obscure if it did.
There were issues putting G4 upgrades into the …

I would double check polarity on your caps, and then just retouch all the solder points once more, make sure everything is good.

Nope. Open traces.
PowerMac G3 All-in-One, iMac G3 - Same Symptoms — #17
It's by no means a Lisa or 128k level of special to me, so I'll more than likely go for the LCD transplant route. Make the machine so much lighter, easier to move, and a tad more p…
