toms565, a FORTRAN77 code which approximates a time-dependent partial differential equation (PDE) in two spatial dimensions.
The text of many ACM toms algorithms is available online through ACM: http://www.acm.org/pubs/calgo or NETLIB: http://www.netlib.org/toms/index.html.

toms565 is available in a FORTRAN77 version.
toms494,
a FORTRAN77 library which
approximates a 1D PDE as a system of ODE's;
this library is commonly called PDEONE;
this is ACM toms algorithm 494.
