- Per Mark Pruden, corrected NZCOM user area specification for CP/M 2.2 files.
- Added some DRI files to CP/M 3 that are documented in the CP/M 3 documentation (LIB, LINK, MAC, RMAC, XREF). They are duplicated in CP/M 2.2 image, so this should be reviewed at some point.
- Added XREF to CP/M 2 disk image for consistency with CP/M 3.
- Updated Catalog.md per Mark Pruden to eliminate obsolete column from table.
