Hi again. Yes you are correct, I did remove additional components to make room for the PSU which was just a little too long to fit along the bottom of the PCB with those in place. My original intention was to leave the inductors and capacitors on each power rail, but I decided the PSU probably...

Merry Christmas.

Thanks, I see you're also attempting to revive an analog board. Good luck with that. I had similar symptoms as you describe in your thread, that is until I blew things up. These are the parts I used to get to this point. pATX Power supply https://www.aliexpress.com/item/32888405080.html...

So it stayed like that until basically two days ago when I found some time to look into it again. In the mean time I ordered some parts, a "PicoATX" PSU that takes an input of 16-28V or whatever, I don't like the look of the 12V input ones, as I'm guessing they just pass the 12V through which...

So... after moving house and finally reaching the end of the year, I finally had some time to look at this again. But a catchup story first.. I did order a bunch of components and try to fix the ABs, I can't remember where I got to with the C1/EAB but the C2/LAB I made some progress after...

Hi, the thick red and white wires are the output from the DC-DC boost converter soldered into the yellow plug on the edge of the last picture.. The white one is negative/ground, but as the boost converter has common negative it is technically surplus to requirements. The red one is +29VDC...

Here's a couple of pictures that show what's going on better. I've ordered cables and a different dc-dc to make an adapter harness. Turns out some Lenovos use 14p molex, and ATX adapters are readily available, so I'll just move pins around and splice wires accordingly.

Hello, I am new here. Figured I'd jump in with something outrageous. Preamble: I've acquired a non working Classic and a Classic II with early (EAB) and late (LAB) analogue boards respectively. I have recapped both ABs and LBs.  The LAB would blow the fuse immediately, eventually 'solved' by...

Kia ora. This is my first post on this forum. I thought this might be a good place to start, I've built a 2032 -> 1/2 AA adapter using veroboard and an appropriate holder. The metal terminals are made from solder lugs from 4mm "banana" sockets. But bits of terminal strip for 18650s would...
