I'm helping someone who bought a new keyboard with a PS2 port for their computer that has an old AT(5-pin DIN) keyboard port. The guy at Staples told his wife that those 6-pin mini-DIN to 5-pin DIN keyboard converters don't work. He said something about some of the functionality of PS2 keyboards won't work if you use one of those converters to plug the PS2 keyboard into an AT-style keyboard port. I've never heard of this. Could anybody with experience plugging a PS2 keyboard into an AT port tell me for sure? Thanks.
