Here is an interesting keyboard because I have not ever seen one like this before. It is a standard 101 key type keyboard made by Advanced Input Devices that looks like the PC Jr Chicklet keyboard. It's similar to the internals of a post sometime back. It is definitely a bad keyboard to actually type on but it is interesting. I'm not sure it's PC compatible but it does fit into a terminal I have that came with the lot but the terminal needs work.
Here's some pics for your "enjoyment"

Looks like conductive rubber dome. Its using an AMD microcontroller. I wonder if Advances Input Devices is an offshoot of AMD (Advanced Micro Devices) I like the UV EPROM.
You mentioned 101 key, but the layout looks more like an 83 key XT layout, albeit with a few differences.
