PDP-11 Unibus Replacement Systems

Our Digital (DEC) Unibus replacements are complete state-of-the-art systems that replace the PDP-11 CPU, memory, disks, tapes, and I/O controllers. The NuPDP Unibus replacement systems are built on an industry-standard platform, offering complete hardware and software compatibility.

NuPDPu Options for DEC Modules

Option modules are plug-and-play replacements for popular legacy Digital interfaces. Option modules install in a NuPDPu 4200 system and offer the same functionality as the Digital equivalent, allowing users to migrate from their Unibus systems to our NuPDPu system and maintain their investment in software and user equipment. Drives, accessories and spares are also available.

Option Modules

An array of Unibus replacement interface controllers / option modules are available to suit a variety of applications. Installation manuals provided on CD.


Available removable system and data drives for the NuPDP systems.
