About Us

Develops/supports Ersatz-11, an all-software emulator of DEC PDP-11 16-bit minicomputers. Current versions exist for Windows, Linux, DOS (still!), eComStation or OS/2, or stand-alone (boots on bare PC hardware with no OS). Standard devices (terminals, disks, tapes, network connections, timers) are emulated using their PC counterparts, and original special-purpose Q-bus and Unibus hardware can be kept and attached to the PC using a PCI adapter card.
