Among the business class laptops, ThinkPads have the best keyboards. Even with the change to island style keyboards, I would say that ThinkPad keyboards still beat all its laptop competitors hands down in the keyboard department. Unlike others, ThinkPad keyboard keys are curved to fit your fingers, they have roughly the same surface area as a desktop full-size keyboard and well spaced so you wouldn't miss a key or have to reach far to get to one.
ThinkPad laptops are well built. However, they are also very expensive, compared to competitors with the same spec. So what do you do if you only like the keyboards? You either buy the official USB or Bluetooth Lenovo ThinkPad keyboards with TrackPoint or make your own adapter for the keyboard that you hold dear.
In this Instructable, I will show you the general steps I took to make a USB adapter for the T60 keyboard and its compatible keyboards, ie. if your keyboard shares the same receptacle as the T60. See step 1.
Let's get started!
