Most document films are very basic slow film emulsions very fine grain, highish contrast & resolution and also usually Ortho so you can work in safelight conditions, usually Red filter.

They will develop in a print developer, but may need a low contrast developer to tame the contrast, in your case that'll have dropped anyway in 26 years,. In general such slow emulsions don't age as badly as most 100.400 ISO films.

A developer like Rodinal used highly dilute 1+200 or 1+300 usually work well to control the contrast, diluting a print developer by a factor of 5 is another option/

Tetenal make Dokumol for use with more modern but similar films, but test it with something you have first to make sure it's usable.
