Great  stuff there.

There is.  Look  on Kevin McQuiggin's site:
http://highgate.comm.sfu.ca/pdp8/

In the  section called "Software", about 1/3 of the way down, look for 
send.c or  better still new-send.c (I call it rsend, on my system).  You 
might  also find rim.c and the BIN loader useful.

They're also on my webpage,  with the corresponding  manpages:
http://www.dunnington.info/public/PDP-8/

That's the  easiest place to get the manpages for rim.c, send.c, rsend.c. 
Here's the  gist (top parts of the manpages):

rim - create RIM-format file from  ASCII addr/instr
rim is a very simple converter.  It  reads in a file containing two
columns of ASCII digits; the  first column is a list of addresses (in
octal) and the second  is a list of machine instructions (also octal).
Output is a  file suitable to feed to the RIM loader on a PDP-8.

send, rsend - send  a file in RIM or BIN format to a PDP-8
send and rsend are  utilities to transmit a RIM format or BIN format
file from a  UNIX (or other) host to a PDP-8 over a serial line.  The
PDP-8 should be running the RIM loader routine prior to  starting
either of these programs.
Input  should be a file in RIM format or BIN format.  Output goes  to
the host serial port, which should be connected via  appropriate cable
to the PDP-8.
send is a  simple version, with built-in serial port settings and a
fixed  delay between characters.  rsend is more sophisticated; it  can
be controlled by command-line options or environment  variables, and
can accept input on stdin.

On a Unix (or  Linux etc) machine you can pipe the output from rim to 
rsend, and if  you're using papertape images (of which there are load on 
the net), rsend  can strip the headers for you.
