Feature Request: Ability to do soft power #2

Open trick-1 opened 1 month ago

trick-1 commented 1 month ago

Some machines like the SPARCclassic LX have software power from the mother board. This allows for power on/off via certain workstation keyboards.

See page 32 and page 77 for some background. https://docs.oracle.com/cd/E19127-01/sparc.classic/801-2176-13/801-2176-13.pdf

From what I can tell there are 3 wires GND Power ON (signal from motherboard) Power OFF (signal from motherboard)(

Would be fantastic to get this feature added.

I have no such machine, so I would not be able to verify the board dimensions or try out that version. If you can donate a broken machine to me, I'll contribute another version :)

Same size PSU, the board you have designed fits just fine.

Appreciate the response. If I see more machines with this I may look at how to do this. I also note that I have a 'soft' power switch on the back instead of a mains side power switch. Based on what you have indicated I suspect that that is also different from the board you have.
