I've been working on an ASCII keyboard that can be used in general for the Apple II, as well as other retrocomputers. Here's a photo of the keyboard configured for Apple II. The keyboard has connectors for Apple II/II+ and for the Apple 1. It supports two different types of keymaps for the Apple II: All CAPS, and Upper/Lower with the repeat key used as a capslock. However, the keymaps can be modified to pretty much anything. This keyboard supports CTRL+BREAK for the /RESET signal, and also supports CLEAR on the Apple 1.
The keyboard can use Cherry MX keys, or Futaba MD4-PCS keys (which I prefer).
I do have to make a couple of modifications still, to make the keyboard fit properly in the Apple II case, but that will happen soon. The whole project is up on GitHub:
I've attached photos of the keyboard configured for the Apple II, and also with a full ASCII layout.
