A CADR

The CADR was the first successful LISP machine, built by the MIT AI Lab as a follow-on to the prototype CONS machine. Many were produced by the AI Lab; several startups (including Symbolics and LMI) produced direct descendants.

Physically, the microcoded CPU was a single huge wire-wrap swing-out bay mounted in the front of an H960 rack. A separate backplane held main memory cards, I/O cards, etc.

The Knight keyboard was used with the MIT-AI ITS machine and CADRs; this is a rendition of the layout
