Ah, the keyboard skins. Very nice for keeping keyboards clean. Unfortunately, they changed the feel of the board a lot too when in use. We had one for our keytronic that we used with our 486 back in the day. I think it is the number one contributor to my brother's carpel tunnel in his left hand. I hope we didn't throw that away. I know we have the keyboard and the computer but I'm not sure what we did with the skin...
