Removed ability from boot up (see ez80cpudrv.adm) to allow for setting of
external memory and io timing using eZ80's W/S config. All timings
must now be specified in terms of eZ80's Bus Cycle setting.
This is to increase compatibility with various external RCBus/RC2014
modules.
Due to eZ80 firmware changes, the configuration was always setting
the I/O Bus Cycle to the maximum setting of 7 - typically most system
will work fine at a setting of 4 B/C
current ez80 firmware version: 0.5.0.234 2025-06-21
- Add hardware detect and initialization code to Centronics driver.
- Fix .gitignore to reflect subdirectory name changes under Tools/cpm/.
- Bump version number in TUNE to reflect Dan's changes.
- Detect Centronics hardware in MBC configuration by default.

* added directory mapping cache. if the same directory is being hit
as last run, we don't need to rebuild the map. will likely break if
you are running more than one at a time, in that the cache will be
ineffective. also, if the directory contents change, this will also break.

* HBIOS Makefile - use env vars for target
Allow build ROM targets to be restricted to just one platform thru use of ENV vars:
ROM_PLATFORM - if defined to a known platform, only this platform is build - defaults to std config
ROM_CONFIG - sets the desired platform config - defaults to std
if the above ENVs are not defined, builds all ROMs
* Added some more gitignores
* Whitespace changes (crlf)
* HBIOS: Force the assembly to fail for vdu drivers if function table count is not correct
* Whitespace: trailing whitespaces
* makefile: updated some make scripts to use when calling subdir makefiles
* linux build: update to Build.sh fix for some platforms
The initialization of the Rom dat file used the pipe (|) operator to build an initial empty file.
But the pipe operator | may sometimes return a non-zero exit code for some linux platforms, if the
the streams are closed before dd has fully processed the stream.
This issue occured on a travis linux ubuntu image.
Solution was to change to redirection.
* Bump version
* Enhance CTC periodic timer
Add ability to use TIMER mode in CTC driver to generate priodic interrupts.
* HBIOS: Added support for sound drivers
New sound driver support with initial support for the SN76489 chip

* SN76489_PORT_RIGHT .EQU $F8 ; PORTS FOR ACCESSING THE SN76489 CHIP (LEFT)
* Miscellaneous Cleanup
No functional changes.
