Good idea. I meant to mention in my followup to Ethan, that the
diagnostics are also available, at

  http://pdp-8.org/papertape/

and the corresponding documentation is available at

  http://www.pdp8.net/query_docs/query_all.html

The papertape images have headers, and the way the BIN loader works, you
need to strip the ASCII header but leave at least part of the top-bit-set
leader part at beginning and end. The "send" program I mentioned will take
care of that.
