This week I worked some on debugging DR-DOS v9. The relevant updates to the debugger and loader are listed in yesterday's blog post dedicated to that. Except for Sunday's update to the manual to list nreserve.eld more completely.
The only other changes concern the list and WarpLink.
DR-DOS v9 trial

In case you're unaware, DR-DOS v9 is a new project that provides a proprietary and closed source DOS that is "a faithful clean-room reimplementation" coupled with the original trademark for DR-DOS. It is "free to download and use for personal, educational, and hobbyist purposes", but does not appear to permit redistribution.
