Tape file number 6 is a DUMPER saveset:
Saveset '"2-SYSTEM"' Fri Apr 15 11:54:20 1977
The saveset was extracted with read20, but it didn't handle the DUMPER format very well.
Richard Cornwell's SIMH installation script for TOPS-20 V3A is included, but doesn't work. Possibly due to wrong MTBOOT version.
