# The first byte is the Z-machine revision; it is always between 1 and 8. We
# had false matches (for instance, inbig5.ocp from the Omega TeX extension as
# well as an occasional MP3 file), so we sanity-check the version number.
#
# It might be possible to sanity-check the release number as well, as it seems
# (at least in classic Infocom games) to always be a relatively small number,
# always under 150 or so, but as this isn't rigorous, we'll wait on that until
# it becomes clear that it's needed.

# If the FX series is the one that had a processor with a 68K-derived

# If it's the i860-based one, they should probably become either the
