I have an IBM model 600 which has not been off for about 4 years. When I tried to bring it up, I had a fan assembly that was bad, replace the fan assemble. Then I had a bad disk drive, replaced disk drive. Now when I try to start the machine I get "disk drive missing from the configuration", I then attempted start DTS and received User Profile Disabled for all the different profiles that may have been used previously. How do I now get into the system?
Software/Hardware used: IBM model 600 OS V5 R1 or maybe V5 R3
