During testing of the NVRAM Switch changes (#451), I found some pre-existing stuff I didn't like, so I have tried to clean things up.
- BOOT_DEFAULT has been replaced by AUTO_CMD
- There is no longer a "default" boot loader command when pressing <enter>.
- An additional SD Module has been developed by Stephen Cousins. Since this module will be distributed as a kit, I think it makes sense to enable support by default. It will do nothing on systems without an SD Module.
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.
- 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.
Added configuration setting VDAEMU_SERKBD which can be used to specify any serial unit # to be used as the keyboard for the video terminal. Default value is $FF which means to use the default hardware keyboard. All other values mean that terminal input is to come from corresponding serial unit #.
Also a couple more tweaks to the p-System boot volume.
I got a very nice email from Eluan Miranda. He pointed out a few inconsistencies in the video and audio driver configurations. I made a few adjustments to clean things up.
- 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.
- 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.
- FD driver will now detect presence of FDC hardware and install if found in all standard configurations
- Does *not* detect type of FDC which must still be set in config
- Added default FD driver MODE to all configs
- Thanks to Alan Cox for the technique!
New sound driver support with initial support for the SN76489 chip
New build configuration entry:
* SN76489ENABLE
Ports are currently locked in with:
* SN76489_PORT_LEFT .EQU $FC ; PORTS FOR ACCESSING THE SN76489 CHIP (LEFT)
* SN76489_PORT_RIGHT .EQU $F8 ; PORTS FOR ACCESSING THE SN76489 CHIP (LEFT)
- Added official support for Steve Cousin's RC2014 Z180 + Native Memory modules (SC111 & SC119). Thanks to Steve for his assistance with this.
- Improved interrupt framework to remove need to extra stubs for each IM2 interrupt handler.
