The Displaywriter is not natively DOS based, but I assume you know this and
that's not what you are saying.  Instead someone internally at IBM or
otherwise ported DOS 1.25 for a non native system (the Displaywriter).  In
short I dont know of any IBM  MS DOS 1.25 for Diplsaywtiter, at.least when
I worked at IBM and they had Dipslaywriters in the Customer Center in
Wilm., DE.
Interesting.  Coincidentally I did build a bootable 8" DOS disk just for
the fun of it but it was DOS 6.22.  The 80 vs 77 tracks issue came.up.
Good.luck :-)

 I have a copy of the disk this image was made from booted on my DW, and am
 trying to load easywriter or a little basrun compatible basic program onto
 an 8" disk with my greaseweazle.
 Not having much luck with the HxC software or winimage poking at that
 image, or loading what I would think would be compatible DOS disks on the
 DW.
 Does anyone have some pointers on tools to help me read this image, and
 make new images and add files?
 Thanks,
