CONS

The CONS machine was the prototype of the CADR LISP machine, built by the MIT AI Lab; only one was ever built, in around 1974.

It was physically very similar to the CADR, with a microcoded CPU implemented in a single huge wire-wrap swing-out bay mounted in the front of an H960 rack; the differences were mostly in the internal architecture of the CPU.
