The V viewer, WinEdt, and a few other proggies i have, do provide earlier versions, along with which is appropriate for different Windows versions. v for example, you can still download win95/98 versions.
All of the 4nt/tcmd32/tcc versions (to vers 25) run on windows 7, They are not necessarily 'supported' on these platforms, but they do run quite nicely.
What would be needed in the page is something like TCC 9 => requires Windows XP, etc. v 6.00a is the last one to run on Win9x. I don't know too much of the recent stuff, because i only recently switched from w5.0 "2000" to 6.1 "seven".
