PS if you're interested in software archaeology and you have the CCP4 library source code handy, check out these routines that I wrote for VAX/VMS. Yes, we kept it in the source distribution all these years! ccp4-7.0-src/checkout/libccp4/fortran/vmsdiskio.for Subroutines QFIEEE & QTIEEE illustrate the horrible data mangling you had to do just to convert between Vax floating-point and IEEE (on top of the byte-swapping!). Those were the days!

This was absolutely necessary in the days when we had a goodly mix of formats (VAX, Convex, Cray, SGI, IBM mainframe, IBM PC, Mac ...). Now pretty well everything is Intel or compatible, i.e. little-endian IEEE format, so this functionality hasn't been real-world tested for aeons and it's possible in the meantime that it's fallen into disrepair.

This may simply be the issue... DEC computers used a different floating point format. Swapping endian-ness would be sufficient, although it might be required in addition.
