- 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.
- Fixed issue recently introduced that kept AFC from being enabled for '650 and '850 chips.
- Increase receive interrupt threshold to 8 which improves interrupt handler efficiency under stress. Credit to Andrew Lynch.
- 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.
- Update TUNE.COM to mute sound card at end of playback when playing via HBIOS.
- Update SN76489 sound driver to use proper default port addresses.
- Modify Phil's CPU MHz speed rounding function to round up anytime speed in KHz is withing 500 KHz of next MHz increment.
- 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.
A suite of Z80 instruction test applications has been added to user area 5 of CP/M 2.2 and ZSDOS disk images.
The location of these applications is likely to change.
