Old Compac Presario 3000+ getting sluggish, freezing has Compac mouse and keyboard. So brother gave me not as old eMachine. Thought I'd use KVM and play music, etc from old Compaq. KVM hooked up. Compaq keyboard works very poorly with eMachine. Compaq mouse doesn't work at all with eMachine -freezes center of screen. Switch to wireless mouse, works fine with eMachine, but then have ot use Compaq mouse if I switch to Compaq PCU. Is there a universal keyboard and mouse that would fix this? Thanks for your help.
