- Update MFPIC related I/O ports from $4x to $1x. The default base address was changed to avoid conflicting with the default I/O range of $40-$7F on ECB Z180 boards.
Added a generic routine in HBIOS to play a beep sound on the first available sound device. Implemented the beep in the ANSI and TTY terminal emulators.
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.
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.
- Improved ASSIGN operation under CP/M 3 to better handle BIOS function invocations
- Added 2PIOTST for testing the DUALPIO MBC board
- Increased default RAM drive size for ZRC
- Fixed the ROM VERIFY functionality on Z280. It was indicating errors incorrectly.
- Revised the way that ZZRCC is built to remove a bunch of complexity that was causing issues. An implication of this is that ZZRCC now treats the data loaded from the CF Card as a ROM disk instead of a RAM disk.
- Updated the assemblers to handle some more Z280 instructions used in HBIOS.
- When building ZZRCC, checks have been added to ensure the ROM image is exactly 256K. The build defaults to 512K and that causes the ZZRCC disk image to be corrupted. This will stop the build if the user fails to specify a 256K ROM size.
The Z280 interbank memory copy uses DMA and did not properly handle scenarios where the source or destination memory range crossed over the banked/common memory boundary. It added a bunch of code, but it is fixed now. This seems to be required by CP/M 3.
- Fix build under Windows (credit to Dean Netherton for finding this).
- Fix ReadMe.md file format to remove superfluous junk at top.
- Improve RAM size detection (work in progress, not part of normal build).
- Added KBDINFO which dumps low level info about keyboards.
- Updated KBDTEST and VDCTEST to put the keyboard controller into translation mode which is what these programs were intended to use.
- Add kbdtest, cvdtest, and cvdonly test programs. They apply to MBC platform only.
- Display more boot info in CVDU and KBD drivers.
- Separate floppy and hard disk content definition files.
- Fixes to ZPMLDR to make it functional with RomWBW.
- Incorporate fixes from the Jon Saxton disassembly in ZPM3 itself.
- Credit to Lars Nelson for finding the ZPM3 source (disassembly).
- Corrects the dynamic disk buffer allocation routine in CBIOS and ASSIGN.COM. They had the DPB assignments inverted causing slightly wrong buffer allocations for RAM and ROM disks.
Credit to Andrew Lynch for discovering this issue.
- Some newer/multi-port UART chips now use MCR:3 to activate the interrupt pin(s), otherwise tri-state. This update sets MCR:3 in all cases.
- Added UARTDUAL config variable that enables detection of a dual UART chip at 0x80 for MBC platform.
- Fixed a typo in TastyBasic Build script.
- Added TMSMODE_RCKBD to support an 8242 keyboard combined with TMS video.
- Worked around a syntax issue from uz80as in rz.asm.
- Improved mechanism to handle forcing a UART detection for SIMH.
