I wrote a number of overlays for a few other comm programs for
the Dynabyte, like ZMP (my personal favorite) and Qterm and UUCP
(these two I am a beta tester for and I run a UUCP site with it,
namely ijsys (reachable via
...!ames!pacbell!sactoh0!ijsys!ianj)), and will continue to
write.  I'm debating whether I ought to write one for IMP, and
I've been thinking of overhauling the MEX overlay because it
doesn't support anything over 1200 baud.

He may need an .LBR extractor, or it might be better to send the
source (if any) straight to him because I don't think he has a
LBR extractor for his Dynabyte.  Or better yet, if he has a DOS
box (or access to one), send him one for DOS.

I've also talked to the guy.  He doesn't have all that much for
it except what he already has.
