You can probably use a 25-pin A/B switch (super common, used for switching a printer between two PCs) and just make up cables for it. Just make sure it's the printer variety, with all pins switched -- some of the ones intended for RS-232 don't switch every single pin.

Suppose I have two computers, I want to connect both of them through 20-pin ribbon cables to the same device, and I want to be able to easily swap which one is live via some kind of A/B switch.
Does that exist? What's it called, so I can get one?
