IN 2019 the world's biggest mine is controlled by lone computer, the Amstrad CPC 189234 mark II. It deals with everything from commanding the Mole-Droids to selling the mined diamonds on the world market. You take the part of a poor computer operator who has devised a means of earning some extra money. You have invented a program to mine 10 of the zones which make up the underground workings. To do this the main computer has been told to set aside three droids for extra duties. But a bug in your program has left you only a limited time in each zone to collect the diamonds before the main computer logs your terminal off. The droids are pretty weak and will be crushed if a rock falls or rolls on to them. However, they are able to use the suction controlled rastor organisor and labelled line (Scroll for short) mover. This invaluable piece of equipment allows the droid to move the line on which it is standing, either left or right. The heavy rocks will crush a droid if one is silly enough to go under it. They move in the following three ways:
- If the space under a rock is vacant or contains a droid it will fall.
- If there is a rock under another rock, the space to the left is vacant and the space below that is vacant, then it will roll to the left.
- Similar to above, but it will check to the right and below. If both are vacant the rock will roll to the right.
Diamonds remain fixed until a droid collects them. After all the diamonds are collected from a zone the droids will move to another.If all the droids are destroyed the main computer will give you a rating and log you out. CWTA
