- I finally realized there was a much simpler way to setup the instance data pointer (IY) for the interrupt handler. This implements the change and reduces the complexity of the code.

For keyboard interface on I/O Multi board. Default is disabled. Requires interrupt #2 jumper set on I/O Multiboard, which is pin 11-12 in P5. Has limitations around port settings. Do not have a video card on my Duo so have been forcing a video driver to load and testing with PIP CON:=UR2: . Let me know what you think.

- BOOT_DEFAULT has been replaced by AUTO_CMD
- There is no longer a "default" boot loader command when pressing <enter>.
- An additional SD Module has been developed by Stephen Cousins. Since this module will be distributed as a kit, I think it makes sense to enable support by default. It will do nothing on systems without an SD Module.
- 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.
* Moved DIOMED_MID variable - so it would be overwritten at start of main Calculation
* Removed code in SYS_GETDIOMED1A - since SYS_GETDIOMED6A did exactly this anyway
* Removed code that set MID_HD - since it would now already be set.
