Word Processor format?

[schmidtd <schmidtd@my-deja.com>]

I've got some DOS disks with files written with an unknown word
processor.  Looking at the disks in CiderPress after transfer, all
files have a filetype of $f3, auxtype of $0000, and a "size" of
156160.  (Which is laughable, since all the files on a disk have that
same size.)

Line breaks seem to have the sequence $00 $40 $03.  The beginning of
files seem to be the sequence $40 $03 $02, and the end-of-file seems
to be the sequence $00 $41 $01 $06.  Looking at a few more files, I
could probably pinpoint the sequence a little better.  But does any of
this start ringing any bells with anyone?
