Xerox Alto/Star archives

Xerox 6085 in Kansas City I happened to mention to one of my son's schoolmates parents that I recycled computers and now I am the lucky recipient of a complete Xerox 6085 system including external 5 1/4 floppy, complete manuals, software, hardware, every thing except the Xerox 4045 laser printer. The previous owner was the original owner. If anyone needs copies of the manuals I will make copies for cost. I found when I hooked it all up and powered up I get a 4 digit code in the upper left corner. I suspect that the system battery may have died. I have 6 large boxes of manuals and software can anyone give me a hint in which manual the hardware troubleshooting guide is found? Is there a guide or index to all the manuals? I remember the great gray or orange walls of DEC manuals, but at least there was an excellent index.
