A brand new computer aided design program from John
Foskett which, judging from the printed results, looks to be a real gem!
Although primarily designed for drawing circuit diagrams, the Atari CAD
program may be used to draw just about anything at all. The Atari CAD
program contains a wide range of electronic symbols, a cross between the
good old favourites, the British Standard BS3939 recommended symbols and
those which look good on the screen and when printed out. To allow for
the maximum drawing space, a mode 8 screen has been used with single
line resolution. An information screen is available at most times when
using the program which gives brief details of all the commands
available and is accessed by pressing the <HELP> key.
Most of the drawing commands are available as a combination of joystick
and keyboard controls and there are numerous preset electronic symbols
to help you on your way. To help you along there are eight drawing files
included which show a couple of single transistor receivers, a coil for
single valve receiver, an XL/XE replacement power supply, a
multivibrator twin LED flasher, a 4 way sequential lamp flasher, a sound
triggered flash unit and a square wave generator. Also included are 15
master blank drawing files each with a special feature around which
wiring layout drawings may be produced. Examples are included to show
how these may be used.
The program is too comprehensive to explain more fully
here but full documentation for its use is included on the disk. If you
have ever designed, or needed, a circuit diagram then this program is a
must. It can also be used for many similar design and layout
applications due to the great deal of care and thought that has gone
into its design. This is probably the best CAD program ever written for
the Atari Classic.
