This is happening because A/UX thinks the console is 1 bit deep and is
writing directly to screen memory. The toolbox program, on the other hand,
has the screen in 8 bit deep mode, and so the screen memory A/UX writes to
gets mapped into the "5 magic boxes".

The best fix would be to find some way to make all console I/O go into a
file rather than onto the screen. X manages to do this, so it can be done,
but right off the top of my head I don't know how to do it. If nobody out
there has a fast-fix program, I'll dig out the X source and try to figure
it out...
