 From  cvs --help-commands
        annotate     Show last revision where each line was modified
In my opinion it should really read:
annotate     Show the revision where each line currently in the file came to 
be as it is now, in the repository.

I have no idea what SCCS command you are speaking of, or what exactly it did, 
even though I used SCCS for ~2 years.



and there is no 'history' command for SCCS or even CSSC:
http://www.opengroup.org/onlinepubs/009695399/toc.htm
http://cssc.sourceforge.net/documentation.shtml
so what are you talking about? (there is no gentle way of asking that.)

It might help us to know Why you want to see deleted lines, as we could 
probably come up with a more useful command, or a better way to use annotate.

Summary, for most of us seeing when a line that currently exists was put into 
a file is useful (get it from annotate), for most of us knowing how MANY lines 
were deleted in a file in a particular revision is useful (get it from log), 
for most of us knowing how a SET of lines changed between two revisions is 
useful (get it from diff).
Because no one has explained why seeing a file with all the deleted lines for 
the whole history of a file is useful:
A) we don't have a command to spit it out.
B) we are having trouble coming up with a useful set of commands for you.
C) annotate don't do that.
