MINE BLASTER (16K Spectrum)
by K Clatworthy
from Popular Computing Weekly (27 October 1983), page 39

The game involves the player's ship blasting as many mines in the time limit
without hitting one and losing a life.

The game uses two machine code routines data for which is held in 710 and
720. One routine reverses the screen (for explosions) and the other scrolls
the top two-thirds of the screen from left to right. The PRINT USR
statements call the machine code routines (lines 90, 340) instead of
RANDOMIZE as this can make the RND function not very random.

Line 10 checks to see if machine code is poked in, if so it goes straight
into the game.
