The mouse is the prototype of modern PC input devices. It was developed over 50 years ago by Douglas Engelbart. The device differs from the new models by the presence of three keys and two disks for moving the cursor.
The coding device is a very traditional prototype of modern keyboards. It has five keys that can be used to type combinations and text with the mouse.
The price at which a set of rare gadgets was sold is a record for all computer mice in history. Engelbart’s mouse is believed to have inspired Steve Jobs to create the Apple Macintosh.
