Delphi was the home-written time-sharing system for the PDP-11/45 I

not sure if it was backed up to tape, or just to duplicate RK05 packs.
In addition to Steve Ward, Chris Terman may remember something about the
Delphi system and backups.

What was the name of the system(s)?
A complication is MIT, being MIT, used their own backup tape format
on some of their Unix systems.
And I should ask Lars if the backup tapes of the
DSSR/RTS machine went
to the MIT archives - they might well have done, and Prof. Ward just
didn't know that.
