There are eight separate subskills to Computer skill: Operate Computer, Write Programs, Defeat Security, Bypass Security, Display Information, Manipulate Programs, Interface Computers and Repair Computers.
Computer programs have levels from 1 to 6, depending on their complexity. Computers also have levels from 1 to 6, depending on what programs they hold. These levels are explained in the descriptions of computers in the Equipment section.
Computer specialists get only one chance to try a subskill on a computer. Success is automatic for some subskills under certain conditions. If the computer was built by aliens (not Dralasites Humans, Vrusk or Yazirians) the success rates for the subskills are modified by -20%.
OPERATING COMPUTERS
Success Rate: 100% + skill level - computer level
Before he can use any other subskill, the computer specialist must be able to operate the particular type of computer he is working on. The chance to successfully operate a particular type of computer is 100% plus 10 x the expert's level, minus 10 x the computer's level. A roll of 96-00 is not automatic failure. Once a specialist has operated a computer successfully, he can operate that computer anytime, unless it is modified.
WRITING PROGRAMS
Success Rate: special
Computer specialists learn to write their own programs. For every skill level the specialist gains, he learns how to write one computer program. The player should pick a program from the list of programs in the Equipment section. When a specialist writes a program, its level is the same as his current level, no matter when he learned the program. For example, a computer specialist that learned the Installation Security program at 1st level can write a 4th level Installation Security program when he reaches the 4th skill level. A specialist can continue learning new programs after he reaches 6th level; each additional program costs 4 experience points to learn.
A specialist that knows how to write a particular program can buy that program at half-price for his own computer. He gains a 20% bonus when trying to manipulate that program or detect security on it in any computer.
DEFEATING SECURITY
Success Rate: 60% + skill level - program level
If a computer has a Computer Security program, characters must break or bypass this program before they can perform any other subskill except repair. Defeating a security program involves a decoding process that can take a long time. Characters trying to break security must spend 1-10 hours working at the computer.
Also, before a specialist tries to manipulate a program, he must find out whether the program itself has any security overrides. A security override will sound an alarm if anyone tries to run, alter or purge the program without first defeating or bypassing the security override. A security override is the same level as the computer's security program. The referee should make the roll to detect a security override secretly, since many programs have no overrides on them.
BYPASSING SECURITY
Success Rate: 30% + skill level - program level
A computer specialist can bypass a security program manually by rewiring the computer. This takes only 1dl0 minutes, but has several disadvantages: the chance for success is lower, it requires a robcomkit, and failing the roll will set off every alarm the computer has.
DISPLAYING INFORMATION
Success Rate: 80% + skill level - computer level
A specialist can use this skill to display any information in the computer's memory. It is especially useful for getting lists of programs that are stored in the computer, personal records, and raw, unprocessed data that is loaded and waiting to be fed into a program. A specialist gets a +20 modifier if he is trying to display information about a program he knows. He can automatically display information about programs he wrote in the computer. If a specialist displays an item successfully, he never needs to roll to display it again.
MANIPULATING PROGRAMS
Success Rate: 50% + skill level - program level
A computer specialist has a chance to successfully run a program, change it or purge it from the computer. The normal chance of success is 50% plus 10 x the character's level, minus 10 x the program's level. If the program is one that the character has learned, he gets a +20% bonus.
A specialist can run a program automatically if it is one he programmed into the computer himself, or if he has run it successfully in this computer before.
A specialist may want to alter a program before running it. For example, a life support program will not let someone shut down the life support system or release a poison into the air. The program could be altered, however, so it would let the operator do either of those things. The referee should note that a character usually must run the program successfully after altering it before the changes will have any effect.
This subskill also lets a specialist try to wipe out a program from a computer's memory, either to destroy the program or to make room for a different program. A character can purge a program automatically if he wrote it in the computer.
INTERFACING COMPUTERS
Success Rate: 30% + skill level - computer level
This subskill lets a character try to link two computers together, either by connecting them with wires or through some communication system such as phone lines or a radio link. Once the two computers are linked, the computer specialist can perform all subskills (except bypass security and repair) from either computer. The chance to successfully interface two computers is 30% plus 10 x the specialist's level, minus 10 x the highest of the two computers' levels.
REPAIRING COMPUTERS
Success Rate. 40% + skill level
When computers break down or are damaged, they can be repaired only by a computer specialist. The level of the computer does not affect the specialist's chance to repair it. Computers are repaired according to the standard repair rule.
Robotics SkillA robotics expert specializes in robots. Robots are complex. mobile machines that are designed to perform specific jobs. Many types of robots are available. Eight common types are described in the Equipment section. The referee can create new types if he wants them.
The robotics skill has nine subskills: Identify, Add Equipment, Repair, Activate/Deactivate, Remove Security Lock, List Functions, Alter Function and Alter Mission.
If the robot is an alien design, then the robotics expert has a -20% modifier on his rolls to perform these subskills. A character must have a robcomkit to work on a robot.
Robot Levels. There are six levels of robots. A robot's level indicates how complex it is. High-level robots can perform more complicated jobs.
Level 1 robots can do only simple jobs. They have been pre-programmed for some specific job and usually can not do any other job. They can not communicate, and often are nothing more than moving, self-operated appliances. An example of a level 1 robot is a maintenance robot that washes and waxes the floors of a building each night.
Level 2 robots can handle several simple jobs. They can receive and follow radio commands in binary machine language sent from some other machine, such as a robot brain or a computer. An example of a level 2 robot is a heavy machine that digs into and smashes up rock, then separates out flecks of gold.
Level 3 robots can do more complicated jobs. In addition, all robots that arc lcvcl 3 or highcr can talk and follow verbal instructions. If these instructions disagree with the robot s programming, it will ignore the orders.
Level 4 robots can act semi-independently. Their programs are flexible, letting the robot accomplish specific goals using different methods. When asked, "How do I get to the starport?" one level 4 service robot might give verbal directions, while another might photocopy a city map and mark the proper route on it.
Level 5 robots can act independently and give orders to other robots (level 6 robots can do this also). For example, a level 5 security robot might decide to stop chasing a criminal because the criminal left victims tied up in a burning house. The robot could organize a rescue mission of other robots.
Level 6 robots are self-programming. They can change the methods they use and even their goals to account for changing conditions. They are almost, but not quite, living machines. A robot brain that runs an automated manufacturing plant and alters the manufacturing process in response to changing economic conditions is an example of a level 6 robot.
Missions. All robots have a mission. A mission is a set of rules that tell the robot what its job is. A robot's mission is the most important order it has, and overrides any orders that conflict with it.
Functions. All robots have several functions that tell them how to accomplish their mission. Low-level robots cannot make decisions, so their functions must be very specific statements. Higher-level robots can make decisions for themselves, so their functions can be more general statements.
For example, a level 3 security robot might have the mission: "Stop all unauthorized personnel from entering this building." Its functions could define "stop" as giving intruders a warning, then using the Restrain program to keep them from entering. "All unauthorized personnel" could be defined as any person or machine that is not wearing a special badge. The robot must be given a function that defines "this building," and another that tells it what areas it must patrol to look for intruders. Another function could instruct it to call the police and report the break-in after an intruder has been restrained.
IDENTIFICATION
Success Rate: 100% + skill level - robot level
A robotics expert has a chance to determine a robot's type and level simply by looking at the robot. The chance is 100% plus the specialist's level x 10, minus the robot's level x 10. Once a robot has been successfully identified, the expert can always identify that robot (unless its appearance is changed).
ADDING EQUIPMENT
Success Rate: 100%
A robotics expert can install new equipment on a robot himself and save the 10% installation fee.
REPAIRING ROBOTS
Success Rate 40% + skill level - robot level
Only robotics experts can repair robots. Robots are repaired according to the standard repair rules.
ACTIVATE/DEACTIVATE
Success Rate: 100%
A robotics expert can deactivate (turn off) a robot regardless of its level. The expert also can activate robots that have been deactivated.
However, before a robotics specialist can deactivate the robot, list its functions, remove its security lock or alter its functions or mission, he must get at the robot's internal circuitry. This requires removing a protective plate, which takes one turn. (The plate can be removed in one turn even if the robot is fighting the character, but the character probably will take damage before he gets the plate off.) Once the plate is off, the robot can be deactivated in one turn.
REMOVING SECURITY LOCKS
Success Rate: 70% + skill level - robot level
If a robot has a security lock, the lock must be removed before someone can list the robot's functions or alter its functions or mission. A robot can be deactivated before the security lock is removed. Once a security lock has been removed it can not be used again.
LISTING FUNCTIONS
Success Rate: 90% + skill level - robot level
A robotics expert can learn a robot's exact mission and functions, as well as get a list of all the programs in the robot, by using this subskill.Once a character has successfully listed the robot's function's, he can always list that robot's functions.
ALTERING FUNCTIONS
Success Rate: 60% + skill level - robot level
A robotics expert can change one of a robot's functions at a time. The character must roll separately for each function altered. Changing an altered function back to the original also requires a new roll. Changing a function takes 1 d10 minutes. If the new function violates the robot's mission or requires programs the robot does not have, the robot will ignore the new function.
ALTERING MISSION
Success Rate: 50% + skill level - robot level
A robotics expert can try to alter a robot's mission. This takes 1d10 minutes plus the robot's level. Changing the robot's mission does not affect its functions; these must be altered individually. Once a mission has been changed, changing it back to the original mission requires another roll. If the new mission requires programs the robot does not have, the robot will still try to follow its new mission however it can.
MALFUNTIONS
If a character fails a roll to remove a security lock or alter a robot's function or mission, the robot can malfunction. When this happens, the referee should roll d100 on the Malfunction Table.
