TUBE (ZX-81)
by Nicholas Watkins
from Sinclair User 19 (October 1983), page 112

Your supply ship will appear, darting about, at the top of the screen.
Pressing any key will stop it. A Tube will then descend from it. Your aim is
to link the tube with the still-moving mothership, to transfer vital
supplies. Slow the movement of the tube with 0 until you are ready to make
the link.

Written for the 16K ZX-81 by Nicholas Watkins of Penn, Wolverhampton.

by Russell Wooberry
from Sinclair User 19 (October 1983), page 114

Russell Wooberry of Farnham, Surrey has written a version of the traditional
game of Knife, Paper, Stone for the 1K or 16K ZX-81. Choose one of the three
by pressing K, P or S as appropriate. The computer will then make its choice
at random and tell you whether you have lost or won. Knife cuts paper, paper
wraps stone, and stone blunts knife. Press enter for another round.
