Atari ST display traces (Revision 3)
----------------
This package contains 16MHZ/DE/#LOAD/8MHz/B2/#HSYNC/#BLANK signal traces of RGB 50Hz display lines taken on different shifters/chipsets.
Don't mind #VSYNC/GPO these probably won't carry meaningfull values.
 
----------------
These captures where done on an Atari 1040STF C070523-001 Rev D board (non-IMP chipset)
and with the following shifters:

C025914-38 PH23-23 5J1 68
C025914-38A PH23-24 6M1 29
IMP C070713-002 Datecode 8833

The display area is B2 low active (aka B2 high=border, B2 low=gfx area).

Files:
C025914-38_low_50hz.*
C025914-38_med_50hz.*
C025914-38A_low_50hz.*
C025914-38A_med_50hz.*
C070713-002_low_50hz.*
C070713-002_med_50hz.*

----------------
These Captures where made on an Atari 1040STFM C070789-001 Rev D board (full IMP chipset) 
with the respective shifters:

IMP C070713-002 Datecode 8833

The display area is B2 high active (aka B2 low=border, B2 high=gfx area).

Files:
C070713-002IMP_med_50hz*.*
C070713-002IMP_low_50hz*.*

The dlX-postfix in the filenames contains the DE-LOAD delay (aka wakestate).

----------------
All PNGs attached where generated via gnuplot, see doplot.sh/.bat and gnuplot.gp
