At the present time, RT-11 is used in running TSX-Plus in three ways:

(a)  To boot TSX-Plus, either it is usual to initiate TSX.SAV via one of the
      UnMapped RT-11 monitors such as RT11SJ or RT11FB since most,
      probably all, Mapped RT-11 monitors are too large.

(b)  Certain RT-11 utilities such as DIR.SAV and PIP.SAV are often used in
       addition to other RT-11 programs such as MACRO.SAV to accomplish
       goals under TSX-Plus which S&H did not write.

(c)  Many of the TSX-Plus device drivers were originally RT-11 device 
      modified to conform to TSX-Plus requirements.

It is probably (c) that is actually the reason that RT-11 is needed to run
TSX-Plus since S&H could have managed to write the boot code in
addition to the RT-11 programs that are used.  But as long as an RT-11
license was a pre-requisite to run TSX-Plus, there really was no need to
also write all of the device drivers from scratch as well.  For the actual
situation, as long as RT-11 was already present, the straight forward
solution was the one used.

If my comments are incorrect, it would be appreciated if someone could
provide the actual information.
