This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Advanced User Defined Character Designer
========================================
Introduction
------------
Many BBC 'B' owner's would have seen a User Defined Character
Designer before now. And all BBC Master owner's would have seen a
designer as there is one supplied on the 'Welcome' Disc.
These designers allow the user to define their own characters and
then automatically work out the necessary values needed to create
that character.
These characters may be used as graphics in games or as fonts for
titles and headings.
The designer has proven itself to be a very useful utility as it
saves the programmer a huge amount of time and eliminates the
need to design the characters on paper.
Unfortunately most Character Designers only allow the user to
design one character at a time. This is a huge disadvantage in
the designing of double height letters and large shapes.
This program however allows the user to design characters
measuring up to 24x24 pixels. That's 9 times the initial
character size!
The next few pages outline how the program is loaded, operated
and the other unique features of this designer.
Loading Instructions
--------------------
The designer will work on a BBC 'B' or higher with DFS fitted.
The program can easily be modified to work on ADFS and TAPE by
making minor changes.
To RUN the program type CHAIN"Loader".
The Title Screen will then load and the user will be advised to
press the Space-Bar. After this the main program will load.
If the DFS uses memory above &E00 this will be reclaimed and the
DFS disabled.
Designing A Character
---------------------
Whenever you enter the main program you will be asked how many
characters you wish to define at a time. This can be anything
from 1 to 9.
Once you reply a large 'blown-up' grid showing your characters
will be drawn in the centre of the screen. A smaller rectangle
representing the actual size of your character will also be drawn
to the right of the screen. Any changes you make to the large
grid will be shown here therefore allowing you to see what
exactly your character will look like.
On the bottom-left-hand corner of the large grid you will see a
'*'. This represents your cursor which you can control by the 4
cursor keys. The <Space-Bar> acts as a toggle allowing you to
change the colour of the square.
Blue = Off
White = On
You will notice any changes you make on the smaller rectangle to
the right.
You will also notice the letters A,B and C along the top of the
grid and the numbers 1,2 and 3 down the left. This allows you to
see what data refers to which character.
Calculating The Values
----------------------
Once you have finished designing your character you should press
<Return>. The computer will now start to calculate the necessary
values required to create your character.
Whenever the values have been calculated you will be asked if you
want them printed on paper. If you do please ensure that the
printer is connected and is on-line.
Users of the BBC Master will them be asked would they like the
values to be sent to a file. If so please consult the section
below on sending data to file.
If the user has a BBC 'B' and has no printer he will have to copy
the values down by hand and then retype them into the computer.
This is because the area of memory used by the DFS is needed to
store the data for the program.
You will be prompted to press the <Space-Bar> and then asked if
you would like to define another character. If not the program
will end with PAGE now set at &E00.
** NOTE ** Please See Listing Below To Read In Data
Send Data To File
-----------------
This option is available to users of the BBC Master which has a
DFS not occupying memory locations above &E00.
This will send the values calculated to an Ascii file called
'C/Data' which can be viewed by typing *PRINT C/Data
The file is increased everytime a new character is sent to it. So
it is important that 'C/Data' is the last file on the Disc.
The file can be deleted at anytime as the 'Loader' program checks
each time it is run to see if C/Data is on the Disc. If not a new
file is created.
The command *EXEC C/Data can also be typed. This will create a
basic program containing the Data needed to create the user
defined characters. This program will be similar to the
following:
10REM Values For User Defined Characters
20REM ==================================
40REM Character A1
50REM ============
70DATA 0,0,0,0,0,0,0,0
90REM Character A2
100REM ============
120DATA 0,0,0,0,0,0,0,0
140REM Character B1
150REM ============
170DATA 0,0,0,0,0,0,0,0
190REM Character B2
200REM ============
220DATA 0,0,0,0,0,0,0,0
The REM lines can be deleted if required to save memory and then
the program can be 'SPOOLed' and merged with a larger program.
A program for reading the data is listed next.
10 FOR K=128 TO 128+x:REM x=No. of Characters.
20 VDU 23,K
30 FOR L=1 TO 8
40 READ n
50 VDU n
60 NEXT
70 NEXT
** NOTE ** 128 may be changed to whatever character the user
wants to define first.
