If I understand you correctly, what you really want is to be able to get
standard video out of a Mac II so you can pump it into any number of tv
monitors (and even record it on tape).

There are several video boards that will do this, and can also overlay
the digital images on live or taped video.  Mass Microsystems has a board
called the Colorspace II that does a very nice job; it can overlay 640x480x
256 colors onto an existing video signal (if desired) and then outputs a
NTSC standard video signal that can be sent to any TV set.

Otherwise, you will have to get a splitter box (which may have to do some
amplification and other techie hooha [Im a software person]) and both the
monitors you use will have to be capable of accepting the Mac II color
signal (eg:they will have to be Mac II monitors).  These are expensive,
though not as expensive as the Colorspace II, which you can probably get
for around $1750, perhaps less.

However, the extra capabilities of boards like this make them well worth
the price; you can do a lot with them.
