We have been using the Mass MicroSystems ColorSpace II board to do video
overlay with the Mac II. By and large I am pleased with the board. It does
what it claims to do and is fairly easy to set up and use. It requires the
use of either and NTSC monitor or multisync type RGB monitor to display its
output. I haven't had a chance to upgrade to a IIi which is supposed to work
with Apple RGB monitor.
You can produce decent quality overlay graphics but they have to be designed
specifically for use as overlays. With the II I am using an interlaced RGB
monitor and your typical 1 pixel line mac graphics (mostly horizontal) will
jitter like mad. Titlebars look especially nasty.
Now we just need someone to produce a $800 video overlay board, and while your
at it throw in a real-time digital frame buffer so I can put my video in a
window.
If anyone has specific questions about the Mass Micro board, feel free to
e-mail or call.
I have no affiliation with Mass Microsystems, just like their board.
