Vintage Alps Keyboard
I recently acquires some interesting items from someone that had an eclectic collection of vintage computer hardware and software. Among the items was this Alps keyboard that I found very interesting. I don’t really know what it was used with because it came as shown but after some clean up, here are some pictures. It appears to use similar key switches to the Apple Macintosh M0110 keyboard but The most interesting thing I found was that the key caps are nowhere near the same. This Alps branded keyboard has texture on the key cap tops; not something I have seen on many keyboards unless they were quite old.
As noted in the comments below (thank you!), this keyboard assembly is from a Heath/Zenith Z-100 computer.
