just picked up 2 S2000 machines
1st is a super Stars spin with error" printer Hardware error" and closure M which I read is a notification of door closed
and 2nd is a Cleopatra 9 line which is a eprom error which ends up at please close main door and does nothing .
Have worked on and repaired many Splus machines but these are my first attempt on the s2000
previous owner claims they were working but had to do battery change after sitting for 2 to 3 yrs
both are coinless with printers and BV. do not currently have clear chip or key chips for these machines
