# SOL keyboard # SOL keyboard with built-in encoder
This keyboard with integrated encoder replicates the keyboard on the SOL-20. This keyboard with integrated encoder replicates the keyboard on the SOL-20.
This keyboard has a sibling Sol-20 keyboard without integrated
encoder [(here)](../keyboard-sol). The two keyboards are identical except for the following difference:
1. This 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.
