	Should be quite easy to put a small hack together at home.
The ST monitor plug has an output called GPO (general purpose
output) which is driven by the sound-chip's parallel port or some such
thing and so produces a logic level signal. It should be possible to
use this output to switch the video signals.

	I haven't really tried this (I have only one monitor!) so I
don't know if the output works as the "ST Internals" book says. If
somebody should try this, I'm sure people on the net will be interested.

ps. I don't recall offhand if there is a +5V supply available on the connector. 
    If it isn't, the hack may not be so direct (but there are many
    ways to get around this minor inconvenience).
