WordStar to ascii text is a less than trivial conversion. But getting it off that 5 1/4 inch floppy disk might be a challenge.
Why on earth would anybody convert a source document for a novel into ascii text? You'd lose all formatting—italics, bolding, unicode characters, smart quotes.
The only reason I brought this (WordStar) up in the first place is that George's editor has been on record describing the walking cluster-f**k that his "word processor" of choice creates.
