Hmmm...
KM-9 on a PDP-9 in 1967.  Not quite an OS and pretty painful (by modern 
standards) DECtape-based system.  All the software we developed was for bare 
metal - a data collection system in a nuclear lab.  (CPU s/n KA9-17.)

TOPS-10 in 1970-74.  Strictly as a user of timesharing system.  Loved it. 
(CPU s/n KA10-13 or -14.)

Some contact with RSX-15 in 1974.

A little work with another PDP-9 in 1975. Disk-based this time.

PDP-11/40 running UNIX 1974-77. Strictly as user.  (Not a DEC OS, so I guess 
it doesn't count.)

RSX-11, various hardware 1977-1990.

RT-11 198?-87

Brush with RSTS ca. 1979

VMS many versions from about 1979 through reirement in 2015.
