[HECnet] SIMH TOPS-20 question --> combined tapeset

[R. Voorhorst]

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.
