Would be interested in anyone know what the Klixon and JF5N parts are for? They are inline with the battery circuit and must provide some sort of feedback mechanism.

That looks like the exact product I ordered. PM your address and I'll send you a set of 8 to get you off the ground. I think they're even still in the shrink wrap.

I started this very project in 2013: - Tore open a 500 battery and took pictures - Bought tabbed AA NiMH cells on Amazon - Bought 3" wide Capton tape on Amazon to tape the battery back up (and to cut masks for adjacent parts during hot air rework) - Both my PowerBook 540c and my 520 stopped...

I wanted those. ; ) If you cast off any parts lemme know.

Micron GAM 0398 appears to be a Micron part number, but not any kind manufacturer reference. This is some sort of programmable logic, do we know the make/model of it? Also, this is the soldered chip in the top right corner(?), do we know what the socketed chip closer to the DIN connector is? I...

Trag - saw you in there, wasn't trying to call you out. If anything, that thread is a little hard to read so I couldn't tell who knew what. Thanks for your honest reply and thanks for digging through the sticky black tar of memories about something you wrote years ago. Thanks for the floppy...

Weird. Here's an email thread between Gamba and some other folks talking about an eBay purchase of the Micron XCEED plans in 2002. Does anyone know what happened to that set of plans? I have to assume they're a different set based on the recent seller's claim of being a Micron engineer. Not to...

How would you implement a modern RAMDAC in this scenario? Would you look for some sort of IC that provides old-world VGA-out support for modern video interfaces and feed it the frame data from the FPGA? I've always thought sourcing the RAMDAC might be the hard part but after looking into...

That's a nice early-ish production SE/30 board. Cleaning: Never had to deal with battery corrosion like this, but if it helps, what I do is... I spray boards with foaming industrial Simple Green (no coloring), let it sit for ten minutes, rinse under a faucet for sheeting action, then pour about...

I have a beat-up 540c that come out of the dump and a working 520 that I just bought off of eBay to get an extra battery and a power adapter. I'm hoping to turn them into a working 540. First Issue: As far as a recell, I've read this thread a few times and I'm wondering if there's any...
