Yesterday I happened to find a site with a large stash of these
caddies.  It was pure chance - I was visiting to go out go-karting with
some folks from there and the first thing I saw sitting beside one of
the desks was a pile of old hardware including an RRD40.  Some of the
caddies were even in their original shrinkwrap (with HP "InfoROM" CDs
inside).

The site's in Melbourne, Australia.  If you're getting desperate for
them, drop me a line and I'll put you in touch with the sysadmin out
there.  They should be fairly cheap to ship out.
