I recently scored few used Mac's and one IICi had this card inside: Viking Controller Mac II/GS & color.

The connector is odd. This card was made for Viking hi-res 19-21" CRT displays at the time, but the guestion remains, can this card be used with modern VGA monitors with anykind of adapter? Anyone ever used these big boys?
