I went from B6700/B7800 to HP 3000 in 1979.  After a year on
STORE, I joined the IMAGE lab and led the development of Intrinsic
Rollback, and monitored the design of Transaction Rollback (never
implemented), and designed Online Backup (also never implemented).

Part of that work was inspired by knowing about Burroughs DMSII!
The main designer of DMSII (and WorkingSet) was Roy Guck, a very
Fred White-like guy (Roy also happened to be my assistant scoutmaster).
Strange parallels!
