Seeking Mouse info There seems to be a difference between PS2 and serial mouse specs beyond the connector. Those labeled "combo" will function in both circuits with the appropriate passive adapter. My problem: In implementing a KVM (Keyboard/Video/Mouse) type switch I need to acquire/fabricate an adapter to allow the use of a PS2 pointing device that is not a "combo" type with a motherboard that supports only the serial type. Further, the switch is also built to PS2 Specs. Preferred solution: An inexpensive adapter that converts between the two specs. Next best solution: The specs so I can fabricate an adapter. Worst case: I have to measure & try... Any pointers?
