I know of very few programs written for the PC 15 years ago that are
still running and usable today, in fact I can't think of any.
I'm still using a roughly 18-year-old release of my favorite typesetting
program, Xerox Ventura Publisher, DOS/GEM Edition, and a roughly
15-year-old release of WordPerfect, on my own personal hardware. There
are some nasty impedance bumps (requiring touch-up in Acrobat) with
certain special-purpose fonts, when I generate PDFs from
Ventura-generated PostScript print files, and I once ended up sending a
supposedly-genuine-Adobe-PostScript color laser printer back to the
vendor the day after it arrived, because it refused to print from
Ventura, but there's nothing I can't deal with.
Then again, I don't allow WinDoze to be installed on my own personal
hardware: my boxes run DOS, or they run Linux, or they run MacOS.
