S9000 Alpha Stars & Bars QH - NVRAM Clear Failed - now machine boot failure

[stlscott]

Hi everyone,

I wanted to change the Denom on my S9000 Alpha Stars & Bars QH.  Everything has been working fine, it was just set to 25c and I wanted to change it to $1.  No issues, plays great, fun game, not a single problem.  No big deal right, but a clear is required.  While doing this process, I changed all 3 batteries as well, they were reading sub-3v so out they went.  So I get the 312 Clear CF from RB (known good source of course) and run the clear.  The NVRAM fails.  I try this several times unsuccessfully.  Each time, each boot, the NVRAM fails (see pic).  So then I boot the machine back up on the original OS/Game CF cards and that now fails too.  Pics of error attached.  Again, no issues with the machine AT ALL until I failed on the clear.  It is the 317 OS and I used a 312 Clear chip.  What would cause the NVRAM clear to fail?  What the heck do i do now?  This is the 512mb MPU 300mhz.

Thanks for any and all help, as always!

Remove the 2. batteries and try a clear without the batteries to see if the error goes away.  If it does, after the clear put the batteries back and do the clear again before you try to boot with os and game.
