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. > >Is there anyone out there who is familiar with this system, its UARTS, > >or who has any ideas about how to get a communications and file transfer > >program set up and running on this system?

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.
