Ersatz-11 emulated tapes

As with disks, Ersatz-11 uses a flexible device-independent interface to allow any supported physical tape device type to emulate any supported PDP-11 tape device type. E11's BOOT command includes support for tape drives, and using a compatible SCSI drive, the emulated PDP-11 can even be booted directly from original DEC operating system distribution tapes. The paper tape bootstrap emulates the absolute loader and can boot from ".LDA" files.
