is at 18 degrees 20 minutes west,

The program can be made to 
draw a section of Britain to any

the scale as it would appear on a 
14 inch television. 

Finally, for all those wishing to 
convert the programs for other

COMMODORE 64 PROGRAMMING 



Thanks to a chip known as SID, 
iht Commodore 64 has powerful 
and well-known sound effects. 

Many magazine listings — in- 
cluding those in HCW — have 
helped programmers make use of 
this chip and the wide range of 
sounds it is capable of producing. 

However, very little has been 
said on how you might incor- 
porate these into a program, 
along with graphics and the usual 
collection of cosmic bug-eyed 
invaders. 

Ideally, it would be nice 10 start 
the chip off playing a tune, or a 
series of sound effects, and leave 
it to carry on by itself, leaving the 
program free to deal with other 

dependent. 

It sounds too good to be true, 
but it is if the music is interrupt 

one-sixtieth of a second the 
interrupt, as well as the updating 
clock, flashing the cursor and so 
on. plays a bit of music. 

My program does all the work 
for you 









The diagram gives a look 
parts of the SID memory map 
that the program uses. Of the 
three voices available, we will use 



When using the program, only 
registers live and six need to be 
set, defining the envelope of the 
voice. If, however, the waveform 
is going to be pulse, registers two 
and three must be set also. 

The volume must also be set, 
normally to its maximum, by 
POKE 54296, IS. 

Scrofrs Music IRQ also has 
some registers which must also be 
set before it is activated. 

Although these must be initial- 
ised, they may also be changed 
during the program, though care 
should betaken with registers 251 
and 252. 

The start pointers point to the 
address in memory - I where the 



Music as you 
run... how 
to make sid 

play by itself 



There's a useful chip inside the 

commodore 64 called SID which 

will play music or create sound 

effects while your program 

gets on with what it's doing. 

David Cristwood explains how 

to use it in your programs 



These notes are in the form of 
high /low byte pairs lo ind 
the frequencies of each note 
user manual, appendix M, givesa 
list of these pairs and their 
corresponding musical notes. 

The machine code routine will 
continue through these pairs until 
it finds a note with a value of 25' 
for the high byte. 

This is taken as a signal lo carry 
on playing the notes lhat — 
pointed to by the repeat po 
This means it can move to :

A TRUE EDUCATIONAL PROGRAM FOR VOUR OR1C-1 

Designed for the 4 to 8 years age group, it also provides useful revision for older children, 
including as it does: 

* FULL RANGE OF MULTIPLICATION TABLES - With a random test of each table 
requiring a verbal answer from the pupil. This can speed up response time and 
improve retention. 

* THREE LEVELS OF TABLE TESTS - Requiring an input answer - 
Demands accuracy 

* FOUR LEVELS OF ADDITION - Requiring input answers 

* FOUR LEVELS OF SUBTRACTION - Requiring input answers 

* FOUR LEVELS OF DIVISION - Requiring input answers 

* * HIGH RESOLUTION DRAWING FACILITY - Enables older children to use skill and 
imagination designing their own drawings directly on to the screen, no 
programming is required. The drawing can even be animated using only four basic 
commands — Hours of fun. For the younger children a 'Draw by Numbers' helps 
with counting. 
This program makes good use of the computer as a teaching aid. Multiplication Tables (the very basis of all 
school maths) can be learnt much more quickly and pleasantly than by conventional methods
