Digby’s Bitpile, Inc., operating as D Bit, is a software development company based in Royalston, Massachusetts. It focuses on creating and supporting Ersatz-11, an all-software emulator for DEC PDP-11 16-bit minicomputers, with versions available for Windows, Linux, DOS, eComStation or OS/2, or as a standalone system that can boot on bare PC hardware. The product maps standard DEC hardware peripherals to PC equivalents while allowing the use of original Q-bus and Unibus hardware via a PCI adapter, enabling users to preserve or reproduce legacy computing environments. The company serves customers seeking to run or preserve vintage minicomputing software and hardware configurations within modern or minimalist computing setups. Digby’s Bitpile is a small software development firm positioned within the broader emulation and retro-computing niche, and it operates from its Royalston location with a compact team. An example recent development is continued support for multiple operating environments, including legacy platforms, to maintain compatibility for its emulator across different host systems.
