Northstar File Transfer from PC

Hi Dwight,

Being able to transfer disk images would be a good thing! The monitor on
the N* is on the disk, and I don't *think* there is one built into ROM
... at least on an unmodified machine. And I believe the monitor is also
a N* DOS program as opposed to something on the CP/M disk, but I'll have
to check that to be certain. The CPU board does have provisions for
adding an EPROM but I'm not certain how it is accessed. Somehow I've
misplaced a box of N* stuff that had a lot of utilities. *Hopefully*, my
HD is still readible although I haven't accessed it in many years. If
not, oh well :).
