There is no way of connecting a PS/2 or an USB keyboard or mouse directly. The easiert way would actually to buy a used STE and replace the keyboard with yours.
If you want to use an adapter, eiffel might help you:

The mouse port usually only needs resoldering, so if you are firm with the soldering iron or know someone who is, it should be easy to repair.
