Turbo Assembler version IV is a programming utility designed specifically for writing machine code routines for use within Basic programs and to this end, the output files are written directly into Basic which avoids the usual problems of converting the conventional object code. The Turbo Assembler uses the standard 6502 assembly language mnemonics together with a few special non-standard features in order to ease the whole process of producing machine code routines for use within Basic. Turbo Assembler version IV can assemble an assembly language source code listing into a machine code file consisting of up to 15 pages or 3840 bytes of code, enough for any machine code routine for use within a Basic program.

Although primarily designed for drawing electrical circuit diagrams, Atari CAD may be used to draw just about anything. Drawing functions are selected from the keyboard and actioned using a joystick whether drawing lines, circles or plotting electronic symbols from the wide range available. Full instructions are available and eight example drawing files, one of which is a replacement XL/XE power supply shown on the Atari CAD screen image above. The remaining drawing files include circuit diagrams for a single transistor receiver and a square wave generator. Also included are 15 blank master drawing files each with a special feature around which wiring layout drawings may be produced.

Whilst exploring a network of caves and pot holes, a rock fall sealed the entrance to the caves with thousands of tones of rock and another way out must be found. There is much exploring and travelling to be done in this adventure, items left in the caves by previous explorers might prove useful but then again they might prove to be a burden. There are many other problems that will have to be solved, for instance the life of torch batteries may need considering and underwater survival might be a useful skill.

The large old house stands alone in its own grounds accessed only by a deserted narrow tree lined lane and isolated by a large, heavy wrought iron gate. The old house, now fallen into disrepair has become the source of great mystery, giving rise to many erie rumours which generates fear into anyone who dares to wander too close. It is said that only women have on occasions been sighted at the house, women who keep themselves to themselves and who appear to walk as if in a dream. This, together with rumours that nobody appears to ever leave the grounds creates further rumours of the living dead. As time passed, the house became known by a name which instill fear into everyone who mentions it and into all those who hear of it. The name most feared is ... Ye Olde House.     Can you solve the mystery of Ye Olde House?

Can you survive in the land where dinosaurs rule and gather enough evidence to prove the existence of living dinosaurs. The land where dinosaurs rule is accessed via a network of caves from where you must find everything you need to accomplish your mission. When in the land where dinosaurs rule, you will encounter both carnivorous and herbivorous creatures, some are relatively safe and some are not. Bare in mind that the dinosaurs move about, they may not be where expected and if you encounter a existence then you probably will not survive. In the land where dinosaurs rule you will also encounter other problems such as rough impenetrable terrain, open plains, pockets of quicksand, etc.

A fast and furious crazy bat and ball game. The object of the game is to score as many goals as possible whilst avoiding all the obstacles which will rebound the ball back to you and if the ball crosses the line behind your bat then a miss is registered.

Recently updated to version III with a modified playing field, a larger bat to improve the game play and a new colour scheme. The object of the game remains the same but Crazy Ball is now more challenging as extra obstacles appear as the game proceeds making the game progressively more difficult.

Space Fighter was originally released on the issue disk included with issue 82 of New Atari User. You are piloting a space ship armed with a powerful laser gun which you must use to defeat the alien fleet and save planet Earth, but the alien fleet are also armed with laser weapons and they are intent on destroying you. On your control panel, (E) turns your engines on/off but you must have your engines on in order to steer your space craft and aim your laser gun. (S) turns your protective shields on/off but the shields do not offer total protection and your space ship can still be damaged. (A) turns the laser gun auto-fire system on/off so that your laser gun automatically fires when on target. The problem is that everything uses fuel so you must judge the situation wisely and destroy the alien fleet before your fuel runs out. During the battle you will receive many hits and you will incur damage to your space craft which will be reported to you via your communications system. Can you save planet Earth or will the alien fleet destroy you?
