@hatter @thomasfuchs Take a look at the Amiga Sidecar, though. It's outrageously inelegant and impractical, and it gets worse and worse the closer you look. The way the Amiga was designed, the expansion slot floats up in the air, requiring really ugly stuff to get something like the Sidecar to work. And also, the mouse and keyboard ports are on the same side as the expansion slot which is ... ugh ... quite lamentable.
