A basic course on logic learned me (long ago) that when a particular line of reasoning states that a contradiction is true, you are allowed to take *any* proposition as beging true. So once you have achieved the above effect (both floating and outputs) I guess a lot more than just 'a few things' can happen..... (like the S/N ratio on the PICList suddenly reaching 1.0).
