I believe you're partly correct. I (still) have a 430HX chipset based
P233 here - for my daughter - that used to be my main system. Most of
the HX based boards allowed you to add an additional bank of cache RAM,
which would support >64Mb. The 430TX chipset would not allow expansion
of the cache RAM, and just flat wouldn't cache >64MB at all. This
caused multiple cache checks on each memory access, hence the
performance slowdown.
