IBM 5251 keyboard

Hi, I recently purchased an old keyboard looking to reuse the parts for another project. I did a little research into exactly what I bought since no one seemed to know. It turns out it is a keyboard for an old IBM 5251 terminal from approximately 1977. Here are some photos: http://www.eldocountry.com/Computer/5251.jpg http://content.techrepublic.com.com/2346-10878_11-3370-4.html Now, I don't really care too much about IBM mainframe terminals or whatever this thing is but as I *do* care about vintage computers. I know how hard it can be to get parts sometimes so before I tear this keyboard up and recycle it into something else, is anyone looking for one of these keyboards? Are they common? Are they rare? It is IBM part 7361073. All I want it for is the case, the mechanical switch keyboard, and the cabling. I was planning on tossing the small controller inside into the trash but I thought I would ask the CCTALK list to see if anyone cares before I rip this keyboard up for my latest project. Anyone? Please speak up now if you are interested. Thanks! Andrew Lynch
