BIO-RHYTHMS
from Sinclair Programs November/December 1982

Since we loaded Bio-rhythms we have not been able to see the TV screen
for interested parties. Everyone in the office is becoming a bio-rhythm
bore.

The program requires your date of birth and the current date and then
displays a neat chart of the month, with curves for the physical,
mental and emotional cycles.

Your physical state varies over a 23-day cycle and relates to your
endurance, strength and agressiveness. The emotional cycle lasts 28
days and governs anger, moodiness and optimism/pessimism. Mentally,
you oscillate between Einstein and ape over a 33-day cycle.

The program was submitted by R Clark, of Saltash, Cornwall.

CITY BOMBER
from Sinclair Programs November/December 1982

City Bomber: this is a version of the well-known arcade game, written
by E Wrigley of Bury, Lancashire, for the Spectrum. As you would expect,
it is in glorious colour and complete with all relevant explosions.

Lines 2 to 16 set up the user definable graphics and should be RUN
before the rest of the program is typed-in. They provide a city of
coloured skyscrapers which you must blast away before you crash into
them. Only one bomb can be in the air at a time and five levels of
difficulty enable you to select the speed of the aircraft.

Graphics notes:
 34-Graphics shifted R, graphics shifted S.
 58-Graphics shifted P, graphics shifted Q.
104-Graphics shifted O.
122-Graphics shifted 8.

CLOCKMAN
from Sinclair Programs November/December 1982

Clockman is a very quick reaction-type game for the 16K Spectrum. It is
so-called because your enemies appear in a circle around the screen as
if on the face of a clock. Your gun, at screen centre, is rotated with
keys 5 and 8 and fired with 1.

Men stay on the screen for a shorter time after every hit, so hitting
more than 40 out of 50 is very good. Fifty out of 50 is impossible.
You can adjust the difficulty of the program by altering the length of
the BEEP in line 180.

Sent by Arthur Douglas, of London E4.

Graphics notes:*
70,80 etc-k.
1000,1010 etc-j,a,b.

note:*this actually seems to be referring to the variables used by the
program.

OUTLAW for Sinclair ZX-81
by D.G. Lomas
from Sinclair Programs, November/December 1982

Some of the best graphics we have seen are the striking feature of
this reaction game for the 16K ZX-81.

D.G. Lomas of Dukinfield, Cheshire, who submitted Outlaw, has managed
to achieve something approaching the effect of a slow animated film by
drawing and re-drawing the outlaws as they fall dead.

There are five of the villains who reach for their guns in a random
order. Your task is to press the appropriate key before they can kill
you. The pleasure of shooting first is enhanced by those fine graphics.

PRIME FACTORS

ALL SCHOOL CHILDREN could do with friendly help with mathematics especially
when trying to find the prime factors of a number. Prime Factors runs on an
unexpanded ZX-80 and, with a few lines changed, will run on a ZX-81.
The ZX-81 version needs an integer statement at lines 25 and 65. The author,
James Annan, of Edinburgh, says that it will not run on the unexpanded ZX-81
but surely at least one reader will find a way.

SHOOT (aka. Sky Shoot)
-----
SKY SHOOT for the Spectrum is a kind of target shoot against the clock. You
have four targets  which you must destroy in an unreasonably short time.
Move left with 1, right with q and fire with 0. A challenging game from David
Price of Glenfields, Caerphilly, which proved too difficult for your
fast-fingered reviewer.

SPACMAN for Sinclair Spectrum
by S.J. Stearn
from Sinclair Programs, November/December 1982

Spacman is a good version of the perennial Pacman, from S.J. Stearn of
Harpenden, Herts, for the 16K Spectrum.

Naturally it suffers in any comparison with arcade machines; there are
no power pills, no exit, and the two ghosts are decidedly more dumb
than their cousins in the amusement halls, though still fast enough to
catch you more often than not.

This listing is a big leap forward in our quest for an arcade-quality
Pacman and provides a good basis for anyone wanting to do further work
on the project. Providing exits, for example, would probably not be
too difficult.

SPIROGRAPH
----------
SPIROGRAPH, from Martin Richards, of Stevenage, Hertfordshire, uses the
hi-res graphics of the Spectrum to fascinating effect. The program produces
graphics in the style of those line-drawing machines with the swinging
weights and turning tables. On the Spectrum, too, it is fun to watch and you
have good pictures.


**********************************************************************


ZAG-BLASTERS
------------
PUT YOUR finger on the laser fire button and get ready to fire because the
Zags are on the way. They are nasty little creatures whose aim is to land on
earth and colonise it. Instructions are contained within the Zagblasters
program along with REM statements to show how the game works. As well as
being fun to play, the game could also teach you how to write invader-type
programs in BASIC. Zag-Blasters was written by J Bedware and J Yeomans, of
Solihull, West Midlands. The game will run on a 16K Spectrum.
