;   ROMWBW DEFAULT BUILD SETTINGS FOR RCBUS Z80 W/ JBL GAME BOARDS AND COLECO STYLE GAMES
;==================================================================================================
;
; THIS FILE DEFINES THE DEFAULT CONFIGURATION SETTINGS FOR THE PLATFORM
; INDICATED ABOVE.  THESE SETTINGS DEFINE THE OFFICIAL BUILD FOR THIS
; PLATFORM AS DISTRIBUTED IN ROMWBW RELEASES.
;
; ROMWBW USES CASCADING CONFIGURATION FILES AS INDICATED BELOW:
;
; cfg_MASTER.asm			- MASTER: CONFIGURATION FILE DEFINES ALL POSSIBLE ROMWBW SETTINGS
; |
; +-> cfg_<platform>.asm		- PLATFORM: DEFAULT SETTINGS FOR SPECIFIC PLATFORM
;     |
;     +-> Config/<plt>_std.asm		- BUILD: SETTINGS FOR EACH OFFICIAL DIST BUILD
;         |
;         +-> Config/<plt>_<cust>.asm	- USER: CUSTOM USER BUILD SETTINGS
;
; THE TOP (MASTER CONFIGURATION) FILE DEFINES ALL POSSIBLE ROMWBW
; CONFIGURATION SETTINGS. EACH FILE BELOW THE MASTER CONFIGURATION FILE
; INHERITS THE CUMULATIVE SETTINGS OF THE FILES ABOVE IT AND MAY
; OVERRIDE THESE SETTINGS AS DESIRED.
;
; OTHER THAN THE TOP MASTER FILE, EACH FILE MUST "#INCLUDE" ITS PARENT
; FILE (SEE #INCLUDE STATEMENT BELOW).  THE TOP TWO FILES SHOULD NOT BE
; MODIFIED.
;
; TO CUSTOMIZE YOUR BUILD SETTINGS YOU SHOULD MODIFY THIS FILE, THE
; DEFAULT BUILD SETTINGS (Config/<platform>_std.asm) OR PREFERABLY
; CREATE AN OPTIONAL CUSTOM USER SETTINGS FILE THAT INCLUDES THE DEFAULT
; BUILD SETTINGS FILE (SEE EXAMPLE Config/SBC_user.asm).
;
; BY CREATING A CUSTOM USER SETTINGS FILE, YOU ARE LESS LIKELY TO BE
; IMPACTED BY FUTURE CHANGES BECAUSE YOU WILL BE INHERITING MOST
; OF YOUR SETTINGS WHICH WILL BE UPDATED BY AUTHORS AS ROMWBW EVOLVES.
;
; PLEASE REFER TO THE CUSTOM BUILD INSTRUCTIONS (README.TXT) IN THE
; SOURCE DIRECTORY (TWO DIRECTORIES ABOVE THIS ONE).
;
; *** WARNING: ASIDE FROM THE MASTER CONFIGURATION FILE, YOU MUST USE
; ".SET" TO OVERRIDE SETTINGS.  THE ASSEMBLER WILL ERROR IF YOU ATTEMPT
; TO USE ".EQU" BECAUSE IT WON'T LET YOU REDEFINE A SETTING WITH ".EQU".
;
; NOTES:
;
; THIS CONFIGURATION ENABLES DRIVERS FOR THE TMS9918 AND SN76489 BOARDS BY J.B. LANGSTON
; AND THE YM2149 BOARD BY ED BRINDLEY. THE TMS9918 IS CONFIGURED TO USE THE COLECOVISION
; PORTS AND HAS INTERRUPTS DISABLED BECAUSE COLECOVISION USES NMI, WHICH WOULD BREAK CP/M
; WHEN ENABLED. IT IS CONFIGURED FOR A 3.686MHZ CPU CLOCK IN ORDER TO BE COMPATIBLE WITH
; COLECOVISION GAMES. THE FIRST SIO PORT IS CONFIGURED TO RUN AT 115200 BPS WITH THE CPU
; RUNNING AT THIS SPEED. THE SECOND SIO PORT IS CONFIGURED TO RUN AT 115200 BPS WITH THE
; SECOND CLOCK SET TO 7.373MHZ. LOWER BAUD RATES CAN BE ACHIEVED ON THE SECOND PORT BY
; MOVING THE SECONDARY CLOCK DIVIDER JUMPER (E.G., 38400 @ 2.458MHZ). THE BAUD RATE DOES
; NOT NEED TO BE CHANGED IN THIS CONFIGURATION FILE IN ORDER TO DO THIS, BUT THE DEVICE
; LIST WILL INCORRECTLY SHOW THE PORT RUNNING AT 115200 REGARDLESS OF THE CLOCK DIVIDER.
;
; THE COMPLETE SET OF DEFAULT CONFIGURATION SETTINGS FOR THIS PLATFORM ARE FOUND IN THE
; CFG_<PLT>.ASM INCLUDED FILE WHICH IS FOUND IN THE PARENT DIRECTORY.  THIS FILE CONTAINS
; COMMON CONFIGURATION SETTINGS THAT OVERRIDE THE DEFAULTS.  IT IS INTENDED THAT YOU MAKE
; YOUR CUSTOMIZATIONS IN THIS FILE AND JUST INHERIT ALL OTHER SETTINGS FROM THE DEFAULTS.
; EVEN BETTER, YOU CAN MAKE A COPY OF THIS FILE WITH A NAME LIKE <PLT>_XXX.ASM AND SPECIFY
; YOUR FILE IN THE BUILD PROCESS.
