I have an old mainboard, type PWA-286C, running a 10 MHz Intel 80286. I have no manuals, so I am looking for documentation on it.
I am especially wondering if there is a connector for the real time clock battery. Maybe J21? Also what the voltage for it might be. Also wondering about the large J17 near the CPU.
Additional question: The board is running a Phoenix 3.0 BIOS. I guess there is no internal setup program? Can I use GSETUP on this?
Here is a picture:
