Joel,
>From what ColorGraphics tells me, their Evolution series cards do not use
any IRQs -- in addition to also using only one slot, imo-- a better way to
go. True, $695 to support 4 monitors, but a small price to pay for the
additional screen real estate. You could also add two cards and support 8
monitors, without need for any IRQs...
(Disclaimer for the bashers-- I have no axe to grind for ColorGraphics, this
information is just the result of my research into the multi-monitor issue)
