A while ago, I picked an IBM M5-2 keyboard out of the trash since I liked the trackball. I use it on my main computer every day. However, one thing that's a little annoying at times is the fact that it's missing two key-caps: one on the Esc key and another on the I key. I was able to find a place where they have a cap for the I key but I just can't find anyone with a cap for the Esc key. Does anyone know where I can find an Esc key cap? It's not that big of a deal but it'll just look and feel a tad better with all the key-caps intact.
