Well I've now repeated you suggested request a couple of thousand times.
Hope that suffices.I realize that it is not a frame grabber. What I am
trying to find is one that works together with the VOC. I am also trying
to see to what extent various graphics' modes are capable of being
supported either by the GS or perhaps a graphics' card in slot 4 with a
12.27MHz dot clock. Clearly such a graphics card with a VOC would be able
to make use of the VOC's capabilities. The 12MHz clock was chosen in order
to obtain square pixels.

I take it these are the ones which use Allison, however they do not appear
to work with the VOC. I am very interested in VOC+frame grabber, VOC alone,
frame grabber alone,graphics card alone or in combination with the above,
and supporting software.

Thank's for the info.
