Revision History

Version   
Date                  Changes

; v2.03 jvc  	Added Force_SMPTE_Time capability to MIDI command set.
; 10/5/01
;
; v2.04 jvc  	Added support for 25fps SMPTE generation locked to PAL.
; 6/4/02
;
; v2.05 jvc 	Added "Ping" command which sends a 9-bit "Set Flag" command to a connected show controller.
; 3/19/03  	The flag number is specified in the incoming message.
;
; v2.06 jvc 	Added support for active mode request from Reproducers.  Reproducers send a 9-bit set flag command
; 7/21/03   	if playing in response to command.
;    	        
;
; v2.07 jvc 	Fixed 2 bugs: 1) Displaying 29.97n instead of 30fps when locked to 29.97n.
; 9/8/03                  2) SMPTE restart after paused at rollover runs from start not preroll time now.
;
; v2.08	jvc	Fixed problem where SMPTE would not run from forced time when Force SMPTE Time command was issued
; 10/2/03   	prior to rolling SMPTE
;
; v2.09 jvc 	Made self-gen timeout infinite by setting frmloss to zero (in constants) for Disneyland Parades.
; 11/2/04
;
; v2.10 jvc	Many changes:
; 02/18/05
;			1)	Toggling FRUN on ML6431 circuit on reset now so that the clocks come up correctly at power-on.
; 			2)	Removed zeroing of ditcount in smpte generation (above reload:) which was done in 2.02
;				This was causing vsynced frame clock to be jumpy as appeared on the MIDI SMPTE Time Window.
;				The Disney Brainstorm analyzer didn't care about it, but I fixed it just in case.   
;			3)	Loading constant Load and Dither values (not from Binloop.exe) for Vsync'd 29.97 SMPTE now 
;				(same as was done for 23.976 and 25) which reduces last bit interval of the frame from 60uS 
;				wider to only 26uS wider than the nominal value (after timer expires Vsync restarts it, so 
;				SMPTE bit clock  was running - and it needs to be running - a little faster.)  It was just a 
;				little too faster and might have been causing the new Disney Show Computer with the Adrianne 
;				SMPTE board in it to report that SMPTE was running fast and having a shit-fit. 
;			4)	Fixed a problem where generated SMPTE would get nasty after a Start SMPTE command caused 
;				yes_smpte to be executed during SMPTE generation.  Now we bail out of writesmpte and go back 
;				into the main forground before executing the new yes_smpte and start over.  
;			5)	Added long delay at initialization (displaying "Initializing" on LCD) to allow Reproducers to 
;				come alive before passing communications through.  Reproducers would intermittantly hang on
;				if they were talked to during power-up sequencing, so this prevents this.
;
; v3.10		Version for new MPEG2 Repro card which configures bit SP1 (spare) as NTSC (0) or PSL (1).
; 2/25/05	This IS compatible with old Repro cards.

  v3.11     With 2.10 we now reset SMPTE generation with an EnableSMPTE while SMPTE is running.  This was
; 6/24/05   not done while idleing, however.  Now it is.  This keeps SMPTE from becoming intermittantly
;           corrupted when restarted after idling.

  v3.12     Corrected bug where pal_ntsc bit was being read improperly causing the VRepro2s to malfunction.
;
; V4.12     Corrected bug where vsync interrupt was still being halved. The Revision E cards connect the
; 2/08/06   field input to the interrupt so this is no longer necessary.  Unfortunately, this makes this version
;           incompatable with Revision D boards.
;
; V6.00     Version for VFD displays, also compatible with older LCD displays.  Removed wait for busy and 
; 6/1/06    CG RAM check in initlcd routine which didn't work correctly on VFD display.
;
; V6.02	    Added new command - Set Sample Rate.
; 10/31/2006
;
; V6.03     Added support for feature which sends a Stop command to all Reproducers whenever incoming SMPTE stops (repeats)
; 2/1/07	or is lost.
;
; V6.04     Now synchronizing Reproducer reset release to sample clock to sync up L/R clocks on all channels for CobraNet.
; 5/16/07
;
; V6.05     Toggling Frame output while "Awaiting SMPTE" to keep Repro16V/D boards alive.
; 9/5/07
;
; V6.06     Now locking 27Mhz driving Video Repros to incoming Video sync whenever it is present (not just when
; 9/21/07   generating SMPTE lock to video syn)
;
; V6.07     Added timestamp output to V16 capability.
; 10/10/07
;
; V6.08     Fixed problem where "Stop Reproducers when SMPTE Stopped or Repeating" feature would always activate when
; 12/10/07  frame repeated even though feature was not turned on.  Also now looking for 3 repeated frames.
