fireworks mode: n. 1. The mode a machine is sometimes said to
be in when it is performing a crash and burn operation. 2. There
is (or was) a more specific meaning of this term in the Amiga
community. The word fireworks described the effects of a
particularly serious crash which prevented the video pointer(s) from
getting reset at the start of the vertical blank. This caused the
DAC to scroll through the entire contents of CHIP (video or
video+CPU) memory. Since each bit plane would scroll separately this
was quite a spectacular effect.
