OT-ish - converting hex output to binary on a Unix platform

Silly question, but maybe someone here's found a nice way of doing this
using standard Unix tools...

I have a few files in hex format (actually ROM dumps) and want to
convert them to binary. Sort of the reverse of the hexdump utility. I'm
not aware of a standard (and probably on-topic!) Unix util to do this,
but maybe someone knows if there is one, or a handy way of doing this
using some of the standard text-processing utils that Unix has...

(files are in the format of 16 pairs of uppercase hex digits per line,
with a trailing space after every pair - even the last one on a line)

I'm rapidly coming to the conclusion that I need to remember some C
again - and I've only just finished emptying my brain of it after the
last time I needed to code in it a couple of months ago :-)

cheers

Jules
