While reverse engineering the Mathbox for Retrocade, I have a *very*
vague memory of someone emailing me about more than one version of the
Mathbox proms. Like something was added for Tempest from the Red
Baron version (or vica-versa). I'm pretty sure there are some mathbox
routines that are never called by Tempest. Maybe they need to be
there for Vortex / Aliens?

But I could easily be confused. Neil would be the person to ask, know
anything about this Neil?
