Yes.  Cyber's, which have 60-bit single precision, have 120-bit double
precision.  Their decendents, the Cray's, have 64-bit single precision, and
128-bit double precision.  They are, however, probably a bit much for you.

An ETA-10 is also a 64-bit s.p. machine, and I believe it is also a 128-bit
d.p. machine.  And, yes, the FORTRAN compilers on all of these machines
support the 128-bit stuff.
