- 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.
- 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.
- 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.
- 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.
- 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.
- The UART driver has been enhanced to allow use of interrupt driven receive buffer and RTS flow control. It will only be used if enabled and the chip detected has no auto-flow control capability.
- Reorganized most of the "common" files into special directories.
- Fixed bug affecting application boot related to ROM checksum test.
- Added support for LiNC sound card at default port address.
- DSKYng now has same features as original DSKY including debug monitor
- Added support for MBS LEDs
- Elevated MBS to a platform instead of just a sub-config of SBC
- Allow any system timer to drive MKY interrupt, not just the TMS driver interrupt.
- Add a build check to ensure that when MKY is enabled, a system timer is also enabled.
Allow specifying a character code which, upon receipt, will reboot system. Only useful/implemented for interrupt driven serial drivers. Currently only implemented for ASCI and SIO. Do *not* use this unless you fully understand the ramifications!!!
Added BOOTCON config variable to allow setting the boot console device. This replaces FORCECON and removes the code that used to rearrange the PCINITTBL.
- Fix minor ACIA bug that only occurs if setting a non-standard baud rate.
- Enhance Z280 UART driver to use C/T for more baud rates and to use Z280 opcodes to speed up interrupt handler a bit.
