So, long story short, I got a Schneider EuroXT with a 21MB HDD and a 720k Floppy. It was in pretty much good condition, not real dust inside, battery was clipped as soon as I opened, and it had some really minor corrosion next to it which was treated with vinegar and Isopropyl alcohol.

I've connected a 8-bit ISA card (which was tested working), and pushed the power button. It turned on but no image showed up. Hard disk wasn't spinning up either (which some lighter taps fixed).
Measuring the PSU, all the rails were over voltage, minus the 12v one which was around 11.5v.
Made a video of it "booting" for the #win31 channel guys here: https://www.youtube.com/watch?v=CvWBwl4grHQ
While this photo isn't mine, I have exactly the same one: http://www.strauch.de/schneider_euro_xt.htm / My board: https://photos.app.goo.gl/iz3jpngi8m6wkFJ78
Things I've tried:
- Pushing all the socketed chips down
- I've frankensteined a cheap atx psu and connected the right voltages to the right pins as the board has a non-standard connector, still no boot (and strangely, 12v was still 11.5v rail on that one).
And I got some questions too:
I'm guessing a normal AT keyboard won't work even though the plug is the same right?
Would there be something to switch on the motherboard so it doesn't use the CGA internal video and uses a ISA Video card instead?
Would it need a bios battery to show up something on the display?
