Might I be the first (possibly of many, forgive this posting if so...)
to recommend volume 3 of the PDP series.  I don't have it in front of
me right now, but I'm positive it is entitled
"Explorations in Parallel and Distributed Processing" by McClelland
and Rumelhart, MIT Press, 1988.
It is only $30.  It contains code for back-prop as well as a number
of other models.  Can't beat the price!  Other good simulators are
SunNet (essentially only back propogation learning in feed-forward
networks, but easy to use on the Sun), and the Rochester connectionist
simulator (more things for the programmer to control than SunNet),
available from Rochester.  Sorry, don't remember the specific contact.
  
I haven't used bpsim.c, though I do have it and am mailing it to
you in a separate note.  Not enough time to play with everything!
