I checked with a friend whose memory is better than mine.
A TRS-80 Model I can duplicate bootable Model III diskettes. The Model III disk controller
cannot produce all the address marks the WDC 1771 can, so a Model III cannot duplicate a
Model I diskette if the OS or bootcode is dependent on having those address marks
present.
So, anyone with a Model I who has good copies of Model III OS disks should be able to help
the poster.
I'd make several copies of each just to control for the age of the media and different
drive alignment. Do one drive 0 to 1 and the other drive 1 to 0.
My system isn't setup yet, else I'd volunteer. Hopefully, I'll have it setup
in a couple of weeks.
