I still have this keyboard along with my first computer, a second-hand IBM PC (5150). The Alt key has some inconsistency registering so I was hoping for some detailed fixing but looks like he just did some deep cleaning and ended up with some bad keys as well.

Someone pointed out that this site to me that sells replacement parts. I was looking at getting new flipper springs for the keys that don't always register.
