Development in the dev branch on CBIOS had broken basic UNA functionality. These fixes seem to correct the problems. A full regression test of UNA has **not** yet been performed.
- Renamed Centronics driver from "CEN" to "LPT" based on input that LPT is the more recognized name for IBM compatible Centronics interfaces.
- Modified LPT hardware detection to be more generic (no longer depends on MBC-specific hardware implementation).
- Fix to CPU speed display for SBC v2 (004 and above) speed selection mechanism.
Some systems use terminal devices (Raspberry Pi, etc.) that take a few seconds to be ready to display console text. The BOOT_DELAY setting can be used to introduce an arbitrary delay (in seconds) in the boot process just prior to text output. This can be used to avoid missing some of the boot messages.
- Minimal support for QP/M by adding a disk image.
- Disk image is not included in combo image, it must be added separately.
- Disk image boots into CP/M 2.2. You must run QINSTALL to configure it and make the disk boot into QP/M.
- It is critical to review the ReadMe.txt file -- default QP/M configuration conflicts with RomWBW use of Page Zero.
- Added some stack space to SYSGEN. It was failing when run with extra CBIOS debugging enabled.
- Cleanup of diskdefs file.
- Updated SIMH executable.
QP/M is a CP/M 2.2 replacement for BDOS/CCP. However, it adds it's own concept of date/time stamping. Support for the QP/M date/time routine has been added. You can configure QP/M to find the vector at address 0x0010.
A sidenote on QP/M. By default, it uses 2 bytes at address 0x0008 to store the current drive/user. This will conflict with RomWBW's use of RST 08 for API function calls. I recommend using address 0x000E when configuring QP/M for the location of the current drive/user.
- PS2INFO now provides a small startup menu to select either MBC or RHYOPHYRE (needs to be expanded to other platforms).
- Battery condition testing enabled by default in RHYOPHYRE.
- Z180 system timer enabled by default in RHYOPHYRE.
- Default ACR in RHYOPHYRE now turns on the status LED to indicate hardware is alive early in boot process.
- Add hardware detect and initialization code to Centronics driver.
- Fix .gitignore to reflect subdirectory name changes under Tools/cpm/.
- Bump version number in TUNE to reflect Dan's changes.
- Detect Centronics hardware in MBC configuration by default.
