Paul,
The tape is simh format
Instead of booting the disk you must boot the tape in simh format and the
MTBOOT prompt will appear.
From there onwards, look at the Tops20 V4.1
installation manual in bitsaver.
Swbx04> att -f tu0 simh
F:\Shares\Distribution\Pdp_10\Media\Tops-20\BB-D867E-BM.tap
Swbx04> b tu0
MTBOOT>
Tape format for V7tape for instance:
; Tape directory for V7.0 TOPS-20 installation tape
; Bytes: 22519060, Records: 8704, Files(EOF marks): 7
TF-Format: raw
0: 2560*597 EOF ; MONITR.EXE
1528320: 2560*125 EOF ; EXEC.EXE
1848320: 2560*8 EOF ; DLUSER.EXE
1868800: 1270 EOF ; DLUSER data
1870070: 2560*36 EOF ; DUMPER.EXE
1962230: 2590*7937 EOF ; DUMPER savesets for <SYSTEM>, etc.
22519060: EOF
EOT:
This tape follows about the same pattern

What I'm trying to do is fill out the missing bits of the TOPS-20 4.1 DECnet
Phase II system I have. I think tape image BB-D867E-BM.tap is the relevant
kit.
When I attached it in TPC format I get some messages that look scary but
perhaps they are just confusing. I don't know how to ask TOPS-20 what it
sees on the tape, though. "dir mt0:" complains that someone else owns the
tape.
