Here's the keyboard we will be working on today. She's not beautiful, but she's mine.

My AEKII is a US made with Alps switches.

Be extremely careful when working with vintage plastics. They are very brittle and can break easily.

While the keys are PBT plastic, the case and spacebar are ABS. ABS plastics yellow over time.

Interestingly, this keyboard came with a number of plastic overlays that sat over the function keys to show their, well, function. Often you will find the area around the function keys has yellowed much less than the rest of the keyboard, as seen in photo 3.
