1. Reconfiguration of TSX-Plus to change the number or type of time-
sharing lines is accomplished entirely by editing the TSGEN.MAC file
and then rebuilding TSX-Plus. In fact, TSX-Plus requires a stripped-
down RT-11 single-job system, and attempts to build a more complex
version of RT-11 will probably lead TSX to tell you that it does not
have enough memory to start. The only requirement of importance is
that RT-11 recognize all loadable device drivers specified for TSX:
terminals are not handled through a loadable driver by TSX.

2. Changing the number and type of lines is well described in the
TSX-Plus System Manager`s Guide. Basically, you need to change the
declared number of lines, then add a LINDEF statement for each new
line. If a new multiplexer is to be added, a new MUXDEF will be
needed as well as a LINDEF. The TSGEN.MAC file adequately describes
the flags that determine whether a line is remote or local, and so
forth.

3. S&H (the people who wrote TSX) are generally competent and helpful.
Call them if you still have problems.

4. TSX-Plus is an extremely nice system for a small multi-user PDP11
system. Apart from anything else, informal tests suggest that it is
a great deal more efficient than either RSX-11 (gak) or 2.9BSD Unix.
I have used it for three years, and recommend it highly.

5. There are hordes of trademarks here. I am in now way associated
with the owners of any of them except as a frequently-dissatisfied
customer. I am more satisfied with TSX than with most other things
in the computer software world.
