That's the general consensus. This is exactly why it took me so many months of constant looking for an A1139, it was the only one that had the 7448A. Funny enough, Apple's own Internal Engineering team made an "Oops" and screwed up the Design datasheets. Obviously this was later corrected before...

Honestly If everything here goes to plan I don't see why not. After all this is said and done I might go back and make a Video Series on YouTube about the steps involved and how to do it yourself. What to look out for-- certain signs relating to certain configs that need to be adjusted etc...

Here we are, Cinebench 11.5 CPU score. From my research we're along the lines of a 1.67-2.00Ghz Intel Atom n450. Which I guess is kind of a thumbs up, as the atom wasn't introduced for another 3-4 years after this guy was. And for the sake of a few laughs I figured I'd compare it to my main...

Give me an hour or two and I'll get that posted for you! :) BTW: If anyone knows any more good comparable benchmarks (As mentioned above) let me know.  As for stability, this thing is a rock. I mean that as in VLC (480p), Virtual PC w/ Windows 98SE Running Landmark Benchmark, Geekbench...

Very strange machine indeed, no doubt a proper dual would have scored much higher than that.  @Elfen Thanks Elfen, stay tuned there will be much more to come as this is just the beginning. I think I've figured out the Voltage Tables, so I should be good to go as high as the Cooling system...

I'll beat that by the end of next week, I promise. I'm expecting another 20% out of this baby as I'm still on stock voltage.  :) Never seen that before, not on the GB database either. Hmm.

Armed with the Engineering Schematics, PCB files, and a soldering iron we have achieved PowerBook glory! http://imgur.com/a/Yviy6 GeekBench: https://browser.primatelabs.com/geekbench2/2603039 With a score of 1136 we've claimed the seat of the highest Geekbench Powerbook Benchmark ever...

I agree with Drone, you could either pull the board and stick it in the oven (~350* @ 5-10 Minutes) hopefully that would reflow everything. Or the more practical way to find a replacement online either as a standalone, or a parts machine.

Curious as to why you'd not recommend the SD option? For the money they seem to be the best option in terms of Cost/MBs/GB, I mean you can get a 64GB UHS-3 1066x SD card for around @$25. I'd be willing to believe it depends on the actual controller chipset that's used on the adapter. A lot of...

You should try to reset the PMU/PRAM. It could be holding data from the old batteries etc.  HOLD: Command+Option+P+R  While booting up from a complete shutdown. The machine will restart, I usually hold it until it reboots after the second time. If that fails: If the computer is on, turn it...

I'd had the same Syba drive as you did, I could never get it to work. My thoughts are that it has two IDE channels but most machines don't support that. I bought the single CF slot, smaller form factor one and that worked right away.

Those adapters are about 2x as much as you should be paying on the Bay. Go with an mSATA to IDE adapter. They will give you the best speeds since they are UMDA7, and lowest access latencys you're going to get in that machine. You can get mSata SSD's probably cheaper than anything other than SD...

Holly smokes, that is a beautiful Floppy Emulator.... I would buy a system just to play with that thing.

Ah! Sorry I missed this reply. I finally found out the one I had used, It's a "Sandisk Extreme Pro", the price's are a lot cheaper than I payed for it (about half), but that's probably due to SSD's becoming so cheap as well...

I agree with this, from what I've seen as well the motherboard Standoffs are sometimes placed in different locations. For example in the top right corner of the motherboard some cases have two standoffs right next to each other, and I've seen others with only one there. Which, I suppose you...

Just a note for anyone interested, I've learned that if you dip all of your Capacitors in Conformal Coating, unless they explode, you should never have to worry about it leaking all over the board again.  Conformal Coating is a Clear Nail Polish like liquid that is intended to be applied on...

Glad to hear you got it working! Are you just using a standard CF to 44 Pin IDE adapter? Like this one: Also, which speed is your CF card? When I overclocked my Libretto 110CT and added a CF card, I put one of those Sandisk Ultra Pro 32GB cards in there, I was looking at around ~120MB/s...

Is that CPU the BGA479 Version, or the Socket M? You could probably upgrade that if you needed too.

I've tried 10.5.8 On the 15" version of that same machine, worked like a charm.  Does that have a 7447A or one of those special 7457/7448A CPU's?

If anyone has the part number of the EEPROM/Controller that is used you could probably find a datasheet to rewrite the register values.  My thought is to dump the ROM of a known good battery pack, then one of another that has been completely drained/used up. You could use a simple Hex editor...
