[sebhc] Re-creating actual floppies from archive

[Dwight Elvey]

Hi Joe
 Now I'm confused. Where did you get the file
you are talking about. I looked on www.sebhc.org/archive/
and only see hard sectored stuff for the CPM files.
Where did you find the zip file? If I can look at the file,
maybe I can help. Otherwise who knows.
Dwight
