Added a new driver category for DSKY (Display/Keypad) devices. Existing DSKY devices were converted into drivers ICM and PKD. These devices were previously DSKY and DSKYNG.
This removes substantial code duplication and recovers significant space in romldr and dbgmon.
- Modified the Disk Device function call (DIODEVICE) to provide new attributes related to disk size and removability.
- Leveraged API change to allow handling drive assignment differently depending on ATAPI vs. ATA interface.
- Support is limited to 512 byte sectors. So, devices such as ATAPI Zip Drives will work. CD-ROM devices will not because they use a larger sector size.
- Added WDATE command courtesy Kevin Boone. See https://github.com/kevinboone/wdate-cpm for more information.
- Final cleanup of PPA/IMM/SYQ drivers including CPU speed compensated timeouts.
IMM Driver has rational timeouts now. It also lights the MG014 LED during activity.
The PPA skeleton just attempts to determine if the PPA interface is present. It does not attempt any I/O.
- Andrew Davidson created a nice Python script to extract/insert p-System volumes from/to disk images. Added a reference to his website in the p-System ReadMe.txt file.
- Added ability to enable VGARC and front panel in default config without I/O conflicts (does **not** support having both types of hardware present at the same time).
- Fixed documentation error in issue #345 reported by @MorfeoMatrixx.
- The use of hardware reset has been improved such that it is generally only used at initial boot up.
- Minor improvements to CF card detection and initialization.
- Implement a simple wait mechanism to accommodate the startup time of the RC2014 SD Pico module.
- Front panel I/O port for SC series of systems has been moved to 0x00 which is consistent with all other systems and avoids some I/O conflicts.
Prior improvement to IDE device detection broke detection of spinning hard disks. IDE registers cannot be used prior to device init completion (spin up). Not a problem for CF, but special steps required to ensure devices are fully initialized before register testing.
- Floppy devices are now configured per-device so that each floppy drive can be different (e.g., first floppy is 3.5" and second floppy is 5.25").
- Removed need to use termination signal on floppy sector I/O.
Addresses issue #318
If serial hardware flow control is enabled, but not working, then a system will appear dead because it won't send any data to the host computer. This change suppresses hardware flow control during boot just to ensure that boot messages can make it to the serial console. This will only be effective for serial interfaces that support dynamic management of HFC.
Edge case where the CPU speed detection routine would overflow in a fast emulator and return a speed of 0.000 MHz. Modified to fail back to the default CPU speed from the config file if an overflow occurs.
- Revamped CTC detection algorithm hoping to handle problem XRBR is having
- Fixed typo in dynamic CPU speed test that caused it to not be properly recorded/reported (credit XRBR)
- Allow use of DEL/RUBOUT keys as backspace in ROM Loader and Debug Monitor
Credit to Jose Luis for discovering this bug and bringing it to my attention. The fix is a small patch on top of the patches previously applied from Jon Saxton. See the ZPM3 directory in Sources for more information.
