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.

!SpiroDraw v1.0 Oct 1994
=========================
This application makes !Draw or sprite files of
Spirograph patterns. They can be saved or
dragged directly into !Draw or !Paint.
An icon is installed on the iconbar. Clicking on
this opens the Options window. Here the radius
of the fixed and moving circles can be set, and
the distance of the pen from the centre of the
moving circle.
The number of teeth on each circle can also be
set, and the line colour selected from the standard
desktop colours. White allows the pen to be moved
without drawing to give partial patterns.
There is a choice of three line widths - chosen so
that drawing the same pattern in thick and then thin
- in different colours - gives an interesting effect.
Clicking on OK will show the design, scaled to
fit in a window. It can be saved by selecting
Save from the menu. This curve is drawn at the
chosen size, so allowing several curves to be
combined in Draw at their proper scale.
The pattern can be seen as it is drawn in the
preview window. If you close this window, the
drawing will be faster, and it can be re-opened
by clicking on the icon-bar icon. It opens
automatically when the pattern is completed.
Partial designs can be drawn by decreasing the
'Loops' value. When either points value is
changed, the loops value is set to give a
complete design - you may then decrease it if
desired.
Different patterns can be combined in the same
picture, and may use different colours. To start
again, select Clear from the menu. The scaling
works best if the largest design is drawn first!
Stop on the menu allows you to stop a long pattern if
you decide you don't like it.
The pattern may be saved as a sprite or a drawfile, or
the values used to generate it may be saved as a text
file, all in the usual manner.
The program multi-tasks while the pattern is being
drawn.
As always, the best way to see what happens is
to do it!!
Updates:
v0.11 : moves correctly between patterns with different
radii.
v0.15 : uses RAM save where possible - eg to !Draw, but not !DrawPlus.
v1.0 : RO3 Version added
Bug in cursor movement fixed
Better choice of colours
