І have run into trouble, as many of you know, using RP/M and attempting to read disks for the Morrow MD-3 which formats to 80-tracks. When I found out a number of things about this system, I remembered that I had a certain program that should be able to tell me all about the system I was using called SYSTAT.COM. The STAT command gives you specific information about the files, the user area, the peripherals, etc, but nothing about the system itself. The RSTAT command is the RP/M version of the same thing giving you the same information. Now I have the 5YSTAT command and thought it would do the same thing.
