Ancient word processor files

[gdt]

One of the issues with writing document filters is the lack of a corpus of real documents in the various ancient formats.

If you have files you have written in the past in Wordstar, PC-Write, XyWrite, DisplayWrite and other pre-Windows word processors then I would be interested in contributions.

My hope would be that such files have little content of value, and thus the corpus could be licensed CC BY-ND 4.0.
