- The post-reset delay of both the IDE and PPIDE drivers has been extended. The SD-IDE adapters need more time to initialize before being ready to behave as proper IDE devices.
- Added support for the FDC section of the Duodyne Disk-IO board.
- Credit and thanks to Martin R for providing a substantial list of suggested fixes and improvements to the User Guide. I have done my best to address them -- others will require more time and will hopefully be addressed in the future.
- The 40 column mode of the TMS driver now conforms to the memory map from the TMS9918 documentation and is also now consistent with the existing TMS9918 video programs from the RC2014 forum.
When using the Z2 memory manager, if the HBIOS exceeds 16K, RTCDEFVAL will not be accessible prior to programming the Z2 memory bank registers. In this corner case the RTC latch could be mis-programmed. This commit introduces a workaround.
- ACIA driver was not properly returning ZF to indicate if it handled an interrupt.
- APPBOOT was failing on ROMless systems because it was copying the HBIOS code overtop of itself.
- Fix ensures that the speaker control bit is set the same as it was initially after playing a tone.
- Reserve 2 bytes in the proxy for a platform dependent tick counter value. Currently for HEATH platform.
- Added support for Duodyne Multi-IO board
- Added support for Duodyne Zilog-IO board
- Added SUPCTS equate in hbios.asm to allow selectively adding code to suppress use of CTS during HBIOS boot
- Added reference in User Guide to Bruce Hall's Assembly Language Programming document
- Detect CTS at startup to ensure it is asserted. If not, disable hardware flow control to avoid stalling the console at boot. Only for UART driver because this is the only place it is currently relevant.
- Add minimal Fuzix instructions to User Guide
- Enable CTC auto-detect by default for RCBus. It causes no problems to auto-detect it and it will stop a CTC from generating unexpected interrupts after a soft restart.
- Upgrade `SUPERSUB` to v1.3 (previously v1.1)
- The naming of ZZRCC was incorrectly ZZRC. Corrected.
- Max Scane has provided a small bug fix for CLRDIR.
- Minor build updates for new HTalk utility.
Driver Device Type ID's have been stored in the upper nibble. However, running out of ID's, I have changed them to occupy the entire byte.
This is a breaking change, so I have updated the minor version number to maintain integrity between components. So, v3.3 will never become a stable release and I am moving directly to v3.4.
- The build process was enhanced by Dean Jenkins to support the Raspberry Pi. Note that the Propeller firmware will not be generated by a RPi build. See Issue #358.
- Initial support for USB storage via CH375/6.
- Based on reports from Martin R, the FDC detection algorithm has been updated to try reading the FDC MSR register twice to try and get the desired value of 0x80.
- Dan Werner's ESP board for Duodyne is working well, so the default Duodyne config has been changed to automatically detect this board.
The EtchedPixels floppy disk controller is known by the identifier
'FDMODE_EPFDC', but the comments in the Config subdirectory have an
incorrect reference to 'EPWDC'. This fix updates the comments to use the
correct name.
Credit to Martin R for reporting that his FDC was not being detected. The delay between FDC status register reads was increased in the detection routine to correct this.
