Yeah, that's the card that @AlpineRaven referenced. There were similar cards made for the PowerBook 190 and 5300, which I believe let you keep the video output port.

I have some Farallon ethernet PCMCIA card which is specifically Mac compatible and works well. You can also use a hacked driver to get the very common 3Com EtherLink III card to work on certain Mac OS versions. See: https://www.floodgap.com/retrotech/mac/enet3c589/ Also, if you have a PiSCSI...

It's not a scam, it's just a last resort. IIRC the way it works is that they send a jolt of power through the electron gun/guns which "blows off" or burns up the back most layer of degraded/worn out phosphor on the tube, which exposes new phosphor under it which brightens the picture. Whether or...

Rejuvenation is not really an option. It has a fair chance of killing the tube, and if it does improve things there is a very high chance that it will go back to being dim or even worse within a short amount of time. Usually bad caps will cause picture instability, rather than a perfect but dim...

2300c definitely has vinegar syndrome too, unfortunately. Nice haul though, that should all clean up nicely!

Let us know what the main BMS chip is. As Joe said, the BQ series chips are generally able to be made to work after a recell. Gets tricky with some of the stuff Panasonic was using, and anything proprietary of course.

I'm an amateur programmer, "learning as I go" and whatnot. I find LLMs helpful when I've got a bug I can't fix. I'll give it my code, ask it to tell me what's wrong, and I make sure I understand what the problem was rather than just blindly trusting anything. 9 times out of 10 it's one tiny...

Nope! I don't. Haven't ever needed one, and never got one with any of the stuff I've bought. I do have the eMate's software CD-ROM and all the original documentation, so I'll install that on my 3400c and see where that gets me.

I just got an eMate 300. Battery holds a brief charge but is beginning to leak so it needs to go. The power adapter it came with is an aftermarket 7.5V 2A supply, which works fine so far. No "too much power" errors. Is it going to be an issue and do I need to source a 1.2A supply? I don't have...

The 7.5V 2A power supply for the 100 Series PowerBooks fails nearly 100% of the time due to the ELNA-brand capacitors inside of it spilling their guts. There's a specific method where you can use a hammer/mallet and a flat-head screwdriver to cleanly bust the brick open, after which you can...

Whoops - somehow this thread slipped by me! Today is "macdat monthly site update day" so this should be up later today!

Can't help with your main issue, but they do not need a working PRAM battery to boot. I believe some/all of the Duos will only boot with one of the two power buttons if the PRAM is dead, but since you are getting power that isn't your problem.

I'll go ahead and add the cap reference to MacDat: https://macdat.net/repair/cap_reference.html Can't wait to see what you accomplish with this project! Edit: The cap reference ZIP file seems to be corrupted - showing as 1K and Windows says it's empty.

I don't know whether or not the voltage load on those caps is enough that same-value tantalum replacement is "not advisable", but as far as I know, that should at worst cause a shortened lifespan for the caps., rather than causing an immediate failure. FWIW, I used tantalums on my PB100 to no...
