- 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.
Lars Nelson has contributed 3 new apps.
- XSUB1 is an improved version of DRI XSUB that allows it to be removed from memory using RMXSUB1
- EX is an early variant of the ZEX batch file processor, but EX runs on ZSDOS (does not require later versions of ZCPR).
- SCOPY is a visual file copy utility which requires ZCPR 3+. It is included on the ZPM disk image.
- The debug monitor will not display the current bank id in the prompt
- The debug monitor has a new command to set the current bank for the lower 32K
NOTE: Bank selection is not possible when running under interrupt mode 1. The command will be rejected with an error.
- Integrate RAMTEST app from Andrew into mainline build process.
- Enhance DSKNGTST app to test on any arbitrary PPI port.
NOTE TO USERS: RAMTEST app is currently only compatible with SBC and MBC hardware.
- Phil Summers' ROM Updater has been given an official/permanent place in the Boot Loader menu.
- Rearranged the order and sizing of the modules in the third ROM bank to allow space for above.
- Made a few minor updates to the DSKYng support code.
- The DSKY(ng) can display disk I/O activity as the system runs. This capability was implemented very erratically. This update overhauls the mechanism, makes it consistent, and implements it across all disk drivers.
- 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.
