Hevi, list:
It was 10 years ago I had to recover a GIS installation with about $200,000
worth of data on it, on a DEC 3000/600 that had been stolen, trashed and
abandoned in a trailer in Tuba City AZ. The machine was full of red sand and
had a resident black widow. It was C-2 secure. It took me months to crack
it, but with some help from former DEC guys in Albuquerque, I got it. It was
pretty simple IIRC.
Let me check my notes, if I still have them, and get back to you on that one.
