I get absolutely nothing -- I tried to zap the pram, nothing. No CD starts this up. The monitor continues to display the amber light -- have tried a different monitor just to rule that out. I took the RAM out thinking I might get some death chimes -- nope. Could the SCSI devices (all internal) set themselves to a different address by themselves? I removed everything external. I'll try to find a brand new battery today. Thanks for your help. pat
