The output from the IBM Monochrome display card is capable
of driving up to 10 displays (I have personally done 7 with no
problem).  All you need to do is get 1 db-9 male connector and
as many db-9 female connectors as you need and wire them in parallel.
It works just great for board room situations or whatever.  The composite
drive from the color board is a totally different story.  It can drive
about 3 monitors (depending on the load of each specific monitor) before
it looses enough current so that there is no sync.  The solution to this
is to get a $12 video distribution amplifer from Radio Shack and put it
between the monitors and the color card.  It just boosts the current
enough to drive at least 10 monitors, probably more.
