I will be making a CP with IPac (2 joysticks and buttons), OptiPac (trackball) and Spinner. I also want to have a keyboard and mouse (not 100% essential but if workable that's my preference). With 2 PS2 ports (looking at connecting the IPac and OptiPac to these) and USB ports (Spinner directly into this), will a wireless keyboard and mouse be able to work with this setup? I am not familiar with the wireless keyboard and mouse - do they need a transmitter/remote type device plugged in to the computer (such as in the PS2 or USB ports) or do they work freely without any plug-ins (such as an installation CD or other)? How responsive are the wireless setups, such as for simple web browsing and basic word documents?
