Is there a key for turning scanlines on and off on Vampire 600 V2 ?
My V4 SA is F11, I was hopping there is a key on my A600.

I do not know, but you can use pokeing
   
apoke $dff3fc 2 $8001 this enables Scanlines
apoke $dff3fc 2 $0001 this disables scanlines
   
see

I want to disable scanlines in scummvm.
The poking did not work.
With my SA I just press F11
 
Please if anyone knows.
 
Thanks

Should read apoke $dff3ec 2 $0001 to turn off.
 
  Still doesn't work on A600.

I think this is done with monitor tooltypes for V2 cards.
 
  There is a textfile "tooltypes" in the SAGA package.


Scanlines=Yes/No
  Default is No.

  This option enable/disable the SAGA SCANLINES hardware mode, for
  the low resolution RTG screenmodes (eg. 320x200, 320x240, ...)
 
  Yes => LowRes screenmodes will use hardware SCANLINES.
  No  => LowRes screenmodes wont use hardware SCANLINES.

Always the same procedure.
 
  open "sys:devs/monitors", select "vampiregfx" and select "show information" from Workbench menu
