As I noted, I'm not that familiar with TSB (I'm an RTE guy). But you might
have to create the desired accounts with the "NEW" sysop command before you
can restore to them.
The last couple of times I tried I did get a message
about something
unsupported and listed something about 200 vs 1500 iirc (block
size??).
Feature level codes, I think.
It asked if I wanted to take responsibility and
continue which I said
yes but still nothing appeared to be restored.
Pages 4-21 and 4-22 of the Access operator's manual (22687-90005, July
1976) say:
Each system is assigned a Feature Level Code identifying the level of
features it supports. Currently, codes are assigned as follows:
Feature Level Code
----------------------------------- ----
2000/C (High-Speed Option) 200
2000/F (All Options) 200
HP 2000 Operating System, Release A 1000
HP 2000 Operating System, Release B 2000
Normally, systems with Feature Level Codes of 1000 or greater cannot
access tapes from systems with Feature Level Codes of less than 1000
and vice versa. For exceptions to this rule, refer to conversion
information in Appendix F.
If the tape reported a feature level code of 1500, then I'd think it was an
Access tape.
Access does come with a conversion program, described in Appendix F of the
above manual, that allows one to dump Access programs in 2000F format.
Presumably, you could load the CSL tape into an Access system and then dump
the programs to a 2000F tape that could be read into the latter system.
I've never tried this myself, though.
Another possibility, if you can get listings of the CSL programs you want,
is to copy-and-paste the source into a logged-in user terminal window
session.
The CSL tape image comes from Bitsavers as well and
was the only copy
I've found. It is listed as the 2000F CSL so figured it was
compatible.
Which specific tape are you using? Bitsavers shows three CSL tapes under
/bits/hp/tapes/2000tsb, but they all seem to be feature level 1500.
Could the Simh hardware configuration in the default
set up need to be
changed?
I don't think that's it. Those couple of test programs installed with the
software kit are loaded from a selective dump magnetic tape image as part
of the sysgen process, so the DUMP and LOAD commands do work with the
hardware setup.
