You may be wasting your time if you're NOT using NANSI.SYS, but you may
become snow-blind if you DO use it!  It works well on slower machines,
but NANSI.SYS causes display snow (i.e., short little horizontal white
lines scattered all over the screen during display write operations)
on my PC-AT with CGA.  At first I thought it might be because I was
running at 8 MHz instead of 6, but slowing down to 6 MHz did not make
it go away.  The snow isn't too objectionable during single character
writes (like when you're typing in a command), but it's fairly nasty
when you do something display-intensive (like a DIR command, or CLS).

I suggest that whoever is responsible for updating NANSI.SYS take a good
look at the way they've written their character output code.  When that
retrace interval comes along, you've got to get that character shipped
out IMMEDIATELY -- time is very tight!  Are you listening?

Speed is great, but snow is obnoxious.  In the meantime, good ol' ANSI.SYS
works just fine.
