Problem with anon cvs

[Michael Blandford <mikey_(_at_)_fimad10_(_dot_)_lanl_(_dot_)_gov>]

If I try to do a cvs get sparc or cvs get sys,  I get something like:

mikey_(_at_)_azalea> cvs get sparc
cvs [server aborted]: there is no repository /cvs/src/sys/arch/sparc          

I havent done a 'get' in a while.  Have things changed or am I doing something
wrong.    I can do a cvs get src but it seems really small.  There is
no /usr.bin or sys directory

Many thanks

Mikey
