These mathematical objects were synthesized by Martin Davis with Emil Post's model, resulting in a particularly simple Post- version of them. One of these was the basis for the ACE, which appeared a decade after they were introduced to provide a diagonal solution to the Entscheidungsproblem in "On Computable Numbers." The set of these is isomorphic to the set of procedures in lambda calculus according to a thesis named for the inventor of lambda calculus and for the namesake of these devices. Every computable algorithm corresponds to one of these objects, which has a several-instruction read/write head and infinite tape. For 10 points, name these model computers named for a British computer science pioneer.
