I think this display routine is totally fucked...  it's possible that that
little mess is what is wrong with spaze invaders on both calculators.  You
may have to rewrite large portions of the program.

As for why it runs on ash but not crash: crash uses more of system memory
than ash does, I would presume could be the cause.  Fix the obvious bugs
so that we rule those out.

BTW: I made a big mistake.  Set BC to 767 not 768.  Sorry about that.
Even if it WERE 960 bytes, you should be using 959 not 960 :)
