They are 256k (32k x 8bit) Static RAM IC's

Soooo I think this is a memory board.... :unsure:

Could be wrong though

I think it uses the RAMs as ROMs so that they are writeable, hence the row of batteries to keep them backed up. Unfortunately the batteries are also the reason why the PCB is falling apart :( Pity, looks like a nice board to have.
