TRAX-11 was a transaction based system. Mostly targeted at the 11/70, unless I remember wrong. However, I seem to remember that TRAX-11 was also somehow tied up with RSX-11M-PLUS, and also the 11/74, but my memory might be confusing me. MicroPower PASCAL was a standalone system I seem to remember. You built the software on something else, like RSX, and then you booted the created system on a bare machine. CAPS-11 is something really old. About the same timeframe as DOS-11. It was obsoleted around 1974 or something, I would suspect. Very short lifetime of some of the earliest systems for the PDP-11.
