Sigma mikhkon Garfield machine

[Nepa Coin Op]

I have a few of these,this is the big one with the bonus wheel up top
 1 boots other 2 both give cd rom/eprom do not match  . CDs look good and clean.... I’m deathly afraid to dig too deep into these not knowing much about them ... I’m sure the working one can use batts, is there any issues to chainging batts on it ? From the manual looks pretty cut n dry ...with keyboard set bios at default and that’s it


 These are really nice games would love to seem them running

Manual says error is incorrect rom or cd .... all 3 units are the same all have same cd with same sw numbers on it ...


I’m thinking maybe bad or dirty cd rom drives Or bios info lost from dead batts



Any info on these is greatly appreciated
Thanks
