'tape0.bz2' is a bzip2'd SIMH tape image for 2.11BSD Patch Level 457 (current as of November 25, 2019). All 9 files of a 2.11 distribution are present on 1 "tape". The file 'simh.ini' is a minimal SIMH file suitable for running the 2.11BSD installation process from a 'ts' tape drive (TS0) to a 'rp06' (RP0). If other devices are wanted edit the file accordingly. The name of the tape image file can be anything but must match the name used on the line "ATTACH TS0 ./tape0" in simh.ini Place the tape0 and simh.ini files into a directory and run "pdp11". At the SIMH prompt type "boot ts0" and follow the normal 2.11 install process.
