Ersatz-11 uses a flexible device-independent interface to allow any supported physical block device type to emulate any supported PDP-11 block device type. Each unit is defined using a simple one-line MOUNT command in the E11.INI initialization text file. Units may also be added, removed, reassigned, or displayed at any time using the pop-up E11 command prompt, without needing to stop and restart PDP-11 emulation. Bootstraps for all bootable block devices are built in to Ersatz-11's BOOT command.
