The CADR was the first successful LISP machine, built by the MIT AI Lab as a follow-on to the prototype CONS machine. Production apparently started in 1978; as of December, 1978, four were operational.
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.
Many were produced by the AI Lab; several startups (including Symbolics and LMI) produced direct descendants.
The Knight keyboard was used with the MIT-AI ITS machine and CADRs; this is a rendition of the layout
