The two keyboards are identical except for the following difference: + +1. The integrated version places the connector closer to the main board keyboard + socket, so the original cable fits more easily. + +1. The non-integrated version requires a piggy-back encoder board. When + installing in a Sol-20, this piggyback board must be mounted on the right + side of the keyboard, and connected with a cable, to avoid mechanical + interference from the Sol main board. + +1. The piggy-back encoder permits use with other machines, via the Apple-1 and + Apple-2 sockets, and two different user-configurable headers. + +1. The piggy-back encoder also includes a UART interface. + The keyboard is designed using KiCad in order to be the most useful for anybody wishing to modify the keyboard for more specific uses, or to add to the project.
