BrainSystems Is Proud to Announce GSBarnDoor Accelerator
13 May 2010

Finally, The ponies are let loose! You want horse power? You are fixing to see horse power! GSBarnDoor is the latest in Apple IIgs Accelerator technology. No longer will acceleration require a slot in your IIgs, but instead will plug seamlessly straight into the CPU slot.

Sleek, streamline design means no interference with inserted cards and unbelievable speed boosts of your Apple IIgs to more than 30MHz.

Beta releases of the GSBarnDoor cards will be available to selected testers later this year. For more info, go to the GSBarnDoor Website at: http://www.gsbarndoor.com
