PowerBook 150 came in today but the Logic board seems dead. No Sign Of Life ... even after it's been plugged in all afternoon. There was a gnarly corrosion on one of the smt resistors. I don't see much else out of place. There are no electrolytics on this board.

The "stackable" memory like the Duo? Yeah, as I recall it has the bottom one with a tall riser and a second stacked on top. I'll refresh my memory when I'm back at the office tomorrow.

Not sure if you tried this already, but always worth a shot to try and power it up with no battery in it. I bought a "dead" PB 170 for cheap that turned out to work great once the battery was out.

Very nice scores!

Yeah, I tried no battery first thing. I think it's dead. I'll give it a round of looking for a problem first. The fuse looked good.

The goodies in that pic are worth their weight in really good stuff, that's the hard part.

Even if this one winds up being DOA, you can nab any 4MB 150 you want. ;)

The RAM adapter slot is the same as the Duo's, but I've never seen that two level upgrade on anything but the 1400 Memory Cards.

What you have there looks like it might be factory stock. Apple part#s or © on the cards? I wonder if, with and without the daughtercard, the memory config works out to be the two (?) upgrade option levels available?

Is there a support bracket for the upgrade cards in your 150?

No bracket, just a standoff that the lower case screw passes through. The riser looks Apple - "JEDI MEMORY B.D". The cards are Kingston - KTA-D230/14 (Kingston, Duo 230 14 MB?).

Yep, that's the Apple adapter, Jedi was the Code Name for the PowerBook 150, so it's right up your alley! [;)] ]'>

Folks who don't like its Passive Matrix LCD must not have cut their PBteeth on a PowerBook 100's 640x400 Single Bit Passive Matrix LCD . . .

. . . 640x480 in Grayscale . . . priceless! :approve:

I've got one that's sucking hind teat on the hacks list ATM . . . one day! [}:)] ]'>

I went to a ham fair swap meet today and couldn't resist grabbing a $10 PowerBook 180 with extra batteries (PowerPlate), all install disks, car charger and assorted software (CPU and RAM Doubler, Connectix PB Tools). I'm leaving the $75 Laser 128 where it is, though.

Picked up a PowerBook Duo 280c from craigslist. I've been needling the seller for a few months and he finally accepted my $25 offer. He threw in a Duo floppy adapter in box, USB Pro keyboard, 1.44 MB floppy drive and the keypad for an adjustable ADB keyboard. The Duo looks and works great
