    IREM 'WW III' 1981

    From readme (Stefan Lindberg)

    The PCB is not working so I don't know if the roms are fine, the sound rom
    was for sure bad it gave different checksums but most of the reads matched
    the MAME soundrom (red alert) it is marked exactly the same "w3s1"(IC5).
    The Bprom matched the Red Alert set also... marked "W3" i think?
    it's hard to see because the sticker has been damaged.
    The other eproms exept one did not match anything in MAME,
    and only one of those had the eprom type markings on it... I read all
    like that type.

     Board set consists of:
        M-27MB (Main board)
        M-27SC
        M-37B  (Sound board)
        M-33 SUB-1
