OK thanks for the info, I found some useful links on VAX:

https://www.cv.nrao.edu/fits/os-support/vms/ieee2vax.c
http://home.fnal.gov/~yang/Notes/ieee_vs_dec_float.txt

However I don't think I'm going to bother supporting it, architectures
like VAX are probably confined to museums and hobbyist's sheds. From
what I can see most of the modern hardware use 2's complement
integer arithmetic and IEEE 754 floating point, but not sure if there
are any specific exceptions I'm not aware of.
