FORMULA ONE (ZX-81)
by Peter Dziwior
from Sinclair User 26 (May 1984)

[Requires edition 2 ZX-81 ROM]

Steer your high-speed, five gear racing car round the track as you compete
in the Sinclair Grand Prix. Your time, distance travelled and gears are
displayed on the screen and a three-second penalty is incurred if you crash
into the barriers. Formula One was written by Peter Dziwior of South
Croydon, Surrey and was the winner of the 16K ZX-81 section of our
Christmas Competition.

[You have the ZX81 game Formula One from Sinclair User May 1984 listed with a]
[strikethrough. I originally submitted this game to you and noted that it    ]
[only ran on a ZX81 with the 2nd edition ROM, and so I presume this is why it]
[is listed with a strikethrough. I've found that the problem is due to the   ]
[machine code routine calling the Break Key Check routine within the ROM, but]
[this routine shifted 3 bytes between the 1st and 2nd edition ROMs. I've     ]
[created a modified version of the game that includes one new BASIC line that]
[detects the ROM edition and modifies the single byte that needs changing.   ]
[The attached program file can therefore be used with both edition ROMs.     ]

by Barry Rawlinson
from Sinclair User 26 (May 1984)

Barry Rawlinson, aged 11, of Welwyn Garden City, Herts wrote Infant IQ
Test for the 48K Spectrum. Teddy is trapped in the cellar and wants to
get out. Each correct answer will let him climb one rung on the ladder
until he is out of the cellar and in the garden. It is a good program
for young children with very good graphics.

MOTORIST MATHS (16K ZX-81)
by Roger Fox
from Sinclair User 26 (May 1984), page 72

Motorist Maths is a simple but graphical program for the 16K ZX-81. The aim
of the game, which is suitable for young children, is to answer all the
questions correctly to be saved from the motorist. You need a minimum of six
sums correct to guarantee your safety.

Motorist Maths was written by Roger Fox of Swindon, Wiltshire.

[I've created a version as listed in the magazine and an alternate version ]
[that fixes a bug and two typos in text that gets printed. None of the     ]
[changes affect the game play as such and so feel free to ignore the       ]
[alternate version if you wish.                                            ]
[There is a spelling error in the word WRONG on line 220 (it is shown in   ]
[the listing as WRON8). This could have been due to a loading error because]
[it seems a very unlikely typo otherwise.                                  ]
[There is a spelling error in the word SUCCEED on line 110 (shown as       ]
[SUCSEED). This could have been poor spelling, but gave the benefit of the ]
[doubt.                                                                    ]
[Line 100 performs a check on the user input after being asked whether to  ]
[display instructions. It uses OR but should use AND. I suspect this was   ]
[just caused by a slip in concentration when creating the logic.      PaulF]

BATTLE 1917

from Sinclair User 26 (May 1984)

Battle 1917 - Mark Lucas (Sinclair User-May 84-Page 73)

Battle 1917 was written for the 48K Spectrum by Mark Lucas and was the winner
of the 1983 Cambridge Award. The Cassette version in published by CCS.
 It is a game with moves which often require as much forethought and calcu-
altion as the moves in a game of chess. Each player has 29 moveable pieces
comprising tanks, artillery, cavalry and infantry and the object of the game
is to kill the opponent's weakest piece, the King. There is a compass onscreen
to aid the movement of pieces and each piece has a certain number of spaces it
can move, as do the pieces in a chess game.
 The pieces manoeuvre across a battlefield featuring lakes, forests, mine-
fields and barbed wire. It is advisable to keep units of four pieces together
in formation, rather than leaving some behind.
 To type in the program first enter the instructions and SAVE them. Then type
in the main listing and once that has been SAVED the program is ready to be
used.

SEMAPHORE (16K ZX-81)
by David Tulett
from Sinclair User 26 (May 1984), page 77

Semaphore was written for the 16K ZX-81 by David Tulett, aged 14, of Edinburgh
and is best played with a friend. The players take turns to write a message
which the other person must decipher. There are six speeds from which to choose
and a lower number will give you slower signals.

The man in the middle of the screen will display the message which has been
input using Semaphore signals. A repeat facility is incorporated if it is
necessary for the message to be viewed again. The game can be played by those
unfamiliar with the semaphore signals, as typing-in the alphabet will give you
a demonstration run.

SHAZMA PLASMA
by Chris Duncan
from Sinclair User 26 (May 1984)

Shoot the approaching enemy with your Shazma Plasma bolts. The bolts are
designed to catch the aliens by surprise. Once the aliens are within
firing range the computer will flash a message on the screen and you
must then fire at them using the "P". The bolts pass through the aliens
and then rebound off the wall, destroying them from behind. There are
several levels to be played and the aliens move at a faster speed as the
game progresses. Written for the 16K Spectrum by Chris Duncan, aged 14,
of Staines, Middlesex.

FRUSTRATION
by John Harlow
from Sinclair User 26 (May 1984)

The object of the game is to visit each of the nine rooms once only with
the exception of room A, which you need to visit twice to pass through
the exit. Each of the nine rooms has four exits. To gain the maximum of
100 points you must only go through each room once, so making a map
would be useful in achieving this. Frustration was written for the 16K
ZX-81 by John Harlow of Bridgwater, Somerset.
