Got recently an old A2000 board. Which is supposed to be functional.
I cannot test it at the moment (my A2000 is not working), but visually it looks fine. The CPU and battery are missing though.
There was battery leakage before the old owner removed it, but the damage doesn't seem serious to me. CPU socket is also corroded, all contacts are green.
Please let me know if there's something that needs to be done with the board regarding (past) leakage and corrosion.
I will use the board in the future to assemble again my A2000.
