It fails to boot with '551' on the LED. I got some hints from my SE about why this is happening, but unfortunately the last resort - rebuilding the system - is not an option, because the thing won't even boot from tape. I am about to start loading diagnostics from floppy, but I thought that by the time that happens, somebody else might be able to give me more clues. Please. rob -- -------------------------------------------------------------------------------- "Unix has its weak points, but its file system is not one of them." -Chris Torek rob rob@dinner.asrc.albany.edu or rds95@leah.albany.edu I have no idea what the uucp path to me is.
