You can run dosbox to load freedos, or an actual version of DOS under
it, and get ansi.sys that way. A bit of a pain, but, it's possible to
do.
I keep a thumb drive with DOS 6.3 around here just for those times
when I really want to run a DOS environment but most of the time
DOSBox does a pretty good job. I still have plenty of DOS tools that
run seemlessly in regular XP.
CE3 an subset of the IBM "E" text editor is very powerful if you are
manipulating text and it runs under XP.
