The battery is still there looking ok. Did not found my keyboard .... I think it s some software emulatipn of 3.1 Roms installed.
I would still consider removing the battery, or taking it to someone to remove it, and putting a coin cell adapter in it. Also if you post a few more pics, particular of the motherboard and expansion cards and maybe run whichamiga or sysinfo and post more information.
I think you could get alot "more" of interest....

I say more because we are all interest in it
