The NuPDP model NuPDPQ 3200 is a complete PDP-11 system replacement for the PDP-11 chassis, CPU, memory, mass storage, and Qbus controllers. Your current PDP-11 disk images can be transferred onto a modern NuPDP system. Qbus controllers can be replaced with QP option modules, new PCI controllers that are software and hardware compatible with Qbus interfaces such as DRQ3B, DRV11-WA, and IEQ11. The QP option modules connect to your existing equipment without software configuration changes. Proprietary Qbus and/or Unibus controllers can optionally be retained in an external chassis. NuPDPQ 3200 is a rack-mounted system for applications requiring up to five QP option modules.
