I have some questions about the TeX files at the Terminator archive.
The archive at atari@terminator.cc.umich.edu lists the following TeX files:

Questions:
1. There appear to be 3 versions of TeX here: ctex, sttex, and texst.
   Is that right?  Which files go together? It looks like texfmt, texfonts,
   texshel2, texshell, texsrc and texst go together.  Right?  Obviously the
   ctex-xxx files go together.  Right?

2. What are the differences between them?  I have a minimal 1040STf with 1 DSDD
   floppy.  Which should I get?

3. There are also dvi programs: dvieps and dvist3_2.  I sent for dvieps and
   encountered CRC errors during arcing.  Any ideas?  Does dvifonts work with
   both dvi programs?  What other files do I need to run dvi?

4. What are the rest of the files?

As you can see, the TeX files are quite large.  So, I don't want to waste
net bandwidth getting files I don't need or can't run.  Any info would be
appreciated.
