This file attempts to give information necessary for you
to bring up the S software necessary to fully support Teletype 5620
Dot Mapped Display and AT&T 630 Multi-Tasking Graphics terminals.

The automatic system generation process should have
already put together most of what you need.  In particular, the
software that runs in the host computer can be compiled on any
machine without any special DMD or MTG software.
The host software emits ASCII characters that represent operations
and operations to special S software that runs inside the
terminals.  This set of ASCII commands is identical for both the
5620 and 630.  The host software is already capable of driving
a 5620 or 630 terminal that has already had the terminal software
downloaded into it.

The difficulty in provinding full support for these terminals is
in cross-compiling the S software that must run in the terminal itself.
Of course, to do this, you will need one or two cross compilers.
For the 5620, you need to have acquired the Software Development package
that includes the cross compiler and libraries appropriate for the
WE32000 processor that resides in the 5620.   For the 630, you need
the Software Development package designed for the MC68000 processor
that resides in the 630.

I will pause for a moment while you go out and get this software ...

Well, I hope you have the software installed now.

That was the hard part.  Now, here's all you have to do.
If you have the 5620 Software Development package installed,
you should set and export shell variable DMD to reflect its location.
For example,
  DMD=/usr/dmd export DMD
Now execute
  cd $F/tty5620
  make
This will make the downloadable file $C/Sterm.5620.

You can do the same kind of operation for the 630.
  DMD=/usr/630 export DMD
  cd $F/tty630
  make
This will make the downloadable file $C/Sterm.630.

You should also edit the S function tty5620 to reflect the
location of the 5620 command 32ld.
Edit function tty630 to contain the location of the command dmdld.
