Help with Blazing 7s MAINS SAFERAM SIGNATURE CORRUPTED - FIXED

[4 Deuces]

Hi!  

Just picked up this machine for $200.  
Upright roundtop with progressive.  
Nickel denom with CC and hopper.
17" monitor looks pretty good (minor burn-in)
BV is missing, but cash can is in place.
Inside/out in great condition.
Glass is great condition.
Overall, I think a good buy and fun project.
Wow this thing is heavy ... must be 300 pounds!

Meter displays C1 and screen displays MAINS SAFERAM SIGNATURE CORRUPTED.

Based on previous posts ...
I'm thinking I need to start with battery?
Then clear/reset - where to get these?  I need a key too - anyone know what key # opens these to MPU?
Then see if C1 clears itself or if I need to reprogram that as well.

Any help/suggestions is always GREATLY appreciated.  :-)

Got the keys and got inside!
Battery tested fine (whew!)
Got the reset chip and went through procedures - GAME WORKING!   


BUT ... progressive still displays C1.
I know I've seen posts on this and that it has to do with communication,
so time to start reading posts and tackle this last step.

Of course, if you know what needs to be done, I'd love to hear from you.   


THANK YOU to Golden Gameroom (a.k.a. Blueridge Slots) for the fantastic BV and Transport with centering pin.  Works great and got it fast!
Rudy's Deals also hooked me up with a face plate below the upper glass and another game for it!  As always, super fast delivery!
