I figured I would start another post since my last one was solved. Thanks for the information! I am currently stuck on a green, call attendant screen which I have attached to this post. I am trying to absorb information on these things as quickly as I can, and as far as I can tell this should go away when I key it. However when keyed, the only thing that happens is the screens go black and reset, but it goes right back to the same screen. When I try to key it again nothing happens, and I get no messages when opening the doors.
I tried pressing the white test button per sixcardmark's advice to no avail. The test button was working when I was getting a non recoverable red error (invalid SafeStorageHeapBlock). I did jostle the brain box a little bit and that is what led to the green attendant screen. Perhaps I went a little bit too hard and something came loose?
Speaking of the brainbox, I would like to remove it and take a look inside and make sure everything is seated, but I have not been able to figure out how to get it out yet and I would like to not damage anything. I am also curious if I have show boot chips, because I am not seeing any license dongles anywhere on the backboard.
Lastly, I know this likely means I am going to need some ekeys and do a ram clear, but I was hoping I could get by without them for the time being.
Sorry for the many questions; it is quite a lot to take in! I appreciate the help!
