I plan to build a box that will hold many cartridges at once and then
either switch between them via software or manually  through a 
switch.  One question....What signal can I use on the expansion slot
to switch out all cartridges but one out of the circuit (preferably
put them in high impedence state) so they will all be powered up, but
not selectable on the buss?  Anyone out there looked at this?

Post answers on net.  Thanx.
