No way, Jose!!  The 1620 comes well after the 704. No Fortran on the
                old 650.  The 650 had its own Fortransit - Fortran
                like but not Fortran.  BTW - the 1620 did all of its
                arithmetic via table-lookup.  The multiplication and
                addition tables had to be loaded into the machine.
                Memory to memory operations and the mode was decimal.
