Black and white. View of the PDP-11 system. Typed description attached to image: "Digital Equipment Corporation's new PDP-11/45, shown above in a system configuration, offers users features usually found ny in larger, more expensive systems. Users can mix bipolar, metal oxide semiconductor (MOS), and core memories. The new computer can operate as much as seven times faster than the PDP-11/20 computer. The PDP-11/45 has an operating speed of 300 nanoseconds for register-to-register instructions. It uses a second Unibus(R) and a dedicated high speed data pth to handle proessor-solid state memory communications, freeing a second memory control to handle up to 40 million bits per second of external Unibus data request. PDP-11/45 systems will range from $15,000 to $200,000 in price. Deliveries will begin in 1972."
