From: "Steve Johnson"
a DEC repairperson showed up to do "preventive
maintenance" and managed
to clobber the nascent file system.
Turns out DEC didn't have any permanent file systems on machines that
small...
A related story (possibly a different version of this one) which I read (can't
remember where, now) was that he trashed the contents of the RS04 fixed-head
hard disk, because on DEC OS's, those were only used for swapping.
