What's the best--that is, cheapest-- way to turn Mac II video output into
an NTSC signal; alternatively, is a simple video grabber, to take NTSC
output and put it into a window, that much more expensive?
Does anybody have product recommendations/warnings about something to do
either of these? I'm looking for the cheapest reasonable-quality solution
to overlay Mac and VDP output.
Thanks,
Adam

If all you need is B/W, buy an Amiga, AMaxII, and a good GenLock.
For some purposes you won't need the genlock. (If you need color,
check on the latest release of AMaxII. The Amiga is color, and it
should be possible to do Mac color, but the Mac ROMs I used didn't
support color...) Since the Amiga output (even when running Mac
software) is already NTSC compatible, you are way ahead of the game,
and if you need to demo Mac software over a standard video system the
whole setup can cost less than $2000.
Also, if money is no object, but video quality is, you can buy an
Amiga 2000 with a Video Toaster from NewTek as a Mac peripheral (for
about $4000) which should give you a production quality image, but I
don't know how easy it is to pump the Mac images through the Toaster.
Flame avoidance: This is a serious post, and yes this does work
very well especially for classroom type settings. There are cases
where I would recommend Macs, but never in situations where you need a
quality NTSC signal.

To answer the original question :), there are a number of options for Mac II video to NTSC conversion. Some answers depend on the type of video adapter you have in it. SOme of the Mac II boards will produce black or white (bi-level) NTSC video just with a special cable. Others will give you grey scale with a special cable. 8*24 and 8*24 GC and RAsterOps boards can have an optional RasterOps $499 video expander attached to give you recordable video directly. Best and cheapest are rarely the same creatures! tj

It not only gives composite video, but can genlock as well. I know they were testing these hardware, but release dates are supposed to be a secret... Thats all I can say at the moment.
