- Add a signature to the start of the font map table to prevent accidentally applying/decompressing invalid font data.
- Improve Z280 font byte retrieval to properly restore the user mode bank.
- 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.
- Related to PR #460
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.
- Rearranged HBIOS code to improve colocation of related code.
- Implemented macros to improve control over assembly diagnostic output.
- Improved handling of diagnostic LEDs.
- Improved application boot bank management.
- Implemented application boot for Z280 systems.
- Moved Z280_BNKSEL into proxy.

- This change avoids clearing the screen every time an OS reset occurs. A non-destructive VDC reset is now performed that leaves the screen contents and cursor position unchanged.
- If an application overwrites the video RAM, then the screen may contain garbage upon return to OS. However, the console will still be functional and the user can just press enter a few times to clear the screen.
- Added ability to enable VGARC and front panel in default config without I/O conflicts (does **not** support having both types of hardware present at the same time).
- Fixed documentation error in issue #345 reported by @MorfeoMatrixx.
