You can change Mathmatica 386 and 387 to use a higher resolution by editing
the display.bat and init.m files.  Just change the line that says something
like   "msdosps -monitor 1 -display vgahi %1 %2 %3 %4" to say "vesa" instead
of "vgahi".  You must then load a VESA driver for your display adaptor unless
it's built in to your hardware.  If you do not do this, it will default to
640x480x16 anyway, so you won't loose anything.  The init.m file is in your
PACKAGES directory.  The display.bat file will display a PostScript file
outside of Mathematica.  I haven't figured out how to save one yet, but you
can unerase the file called "tempfile" in the directory that you told the
MINSTALL program to put temporary PostScript files.  Of course, you have to
generate Graphics first.  I kinda like "Plot3D[1/(x*x+y*y),{x,-2,2},{y,-2,2}]"
Upper/Lower case is important everywhere including the batch files, but you
should know this if you've ever used Mathematica.

It turns out the MINSTALL programs are exactly the same for both the 386 and
387 versions, so just get the cracked MINSTALL for the 386 version if you
got the 387 version.  The crack was one of the simplest ones I've ever done,
As far as I can tell, only MINSTALL worries about the password.
