The PDP-3 (Programmed Data Processor-3) was the first 36-bit machine DEC (Digital Equipment Corporation) designed, although it was not offered as a product.

Only one PDP-3 was built, and that was by a customer in 1960. Architecturally, the PDP-3 was essentially a PDP-1 stretched to 36-bit word width.
