Integrated circuit stubs in a point-to-point system

A system comprising:

• multiple integrated circuit stubs coupled in series, at least one of the integrated circuit stubs including the following:
• first conductors to carry signals to and from a first adjacent one of the integrated circuit stubs;
• second conductors to carry signals to and from a second adjacent one of the integrated circuit stubs,
• third conductors to carry signals to and from an integrated circuit chip;
• and
• first drivers, second drivers, and third drivers, wherein the first drivers receive first external signals from the first conductors and third external signals from the third conductors and drive them onto the second conductors, and the second drivers receive the first external signals from the first conductors and second external signals from the second conductors and drive them onto the third conductors, and the third drivers receive the second external signals from the second conductors and third external signals from the third conductors and drive them onto the first conductors.
