Very interesting link, thank you. Those manual scans are very good much better then the ones I found on google.
So it seems this board has a deep memory of a failed battery state going by that russian post, and like I suspect something to do with bios/odin chip preventing it posting in normal circumstances.
I got rid of the keyboard error lock by booting up with no keyboard then plugging it in, entered bios went past post did a few hard and soft reboot and keyboard working ok BUT this is all with the cmos clear jumper on, still getting blocked booting with no battery or external coin in a holder which I measured 3.2V.
going to have a break maybye for a day now.
so next on agenda is
1. check if keyboard error comes back after board fully drains after a day
2. check regulator output inside cpu socket
3. dump the bios image to pc
4? I got a barrel battery that has charge I might solder it on original pins if get bored
I don't have a post card unfortunately but I have been meaning to get one for a while they are pretty cheap
