Electronics And Computers ========================= ## Networking/Hacking/Cracking ### Connecting If your character has legitimate access to a computer they can connect with a DC 15 Roll (or just take a 10). The Computers will only allow certain actions for a user to take. if the computer has multiple users it can have a access control program that assigns a different access to different users. * User Actions * Become Admin * Read Data Store * Modify Data Store * Run programs * Create programs * Control attached devices * Admin Actions * Add user * Remove user * Disable system security * Access system logs Some Systems may require local physical access to use at all, such as a computer not connected to a network. ### Elevating Privileges In general, there are three levels of access to a system: * Public (No rolls required, but you can only access public data) * User (approved users) * Admin (The maintainer of the system) The Networks security is represented in a tree of DCs that must be beaten in order to obtain certain access levels. If you have physical access to the machine the first level of security can count as immediately bypassed. if you are allowed to open the machine your character can take 20s on Checks. AS the cracker progress thru the security levels. failures are totaled. If the cracker fails too many times (Equal to the detection number) they are detected and the system will take the indicated counter action. The system may notify the admin, or just lock out all connection attempts for a period of time. #### Examples ##### Standard PC - with different Passwords for User and Admin accounts * 25 * 25 USER * 25 ADMIN * Detection: 8 * Response: Take system offline in 21 hours ##### Crunchy Outside Gooey Inside Network * 25 * 40 * 25 USER * 25 ADMIN * Detection: 2 * Response: Immediately block futher attempts for 20 minutes * Access Level: * Public - Pointless website, admin contact info. * User - Full access to all users data and all devices on network * Admin - Standard ##### Local Police Network * 25 * 30 * 30 USER * 35 * 40 ADMIN * Detection: 6 * Response: Expect a door knock in 30 minutes * Access Levels: * Public - Website containing phone numbers and local ordinances. * User (Most officers) - Ability to read and update crime and criminal records * Admin - Add Users, lock out certain case files. ##### Computer Controlled Door lock * 25 * 45 USER * 25 ADMIN * Detection: 2 * Response: Activate alarm, contact security company. * Access Levels: * Public - Bland Greeting * User - Lock, Unlock Door, Set off Alarm * Admin - Add Users, Disable Alarm ### Code Breaking Data pulled off a computer may still be encrypted, this would require additional checks to decrypt as well as a large amount of time. A person can make one try per hour. A computer may try (KNO x 10) times faster. This isn't realistic, but a little room for super human ability and maybe a little insight helps. ##### Cheap Commercial Encryption * DC: 25 * Total Progress: 5000 ##### Good Encryption * DC: 25 * Total Progress: 20000000000000 (2e+13) ### Social Engineering Never underestimate the value of people skills to obtain information. An Enchanter will beat an Expert to the data on a system 9 times out of 10. A chain is only as strong as its weakest link. And a system's resist persuasion is only as high as its lowest user or admin. Actually more computer literate users are more resistant to these kind of schemes. A user may use WIL+Network Hacking to resist attempts to aquire their access statistics. ## Computers Base Models |KNO |Memory |UI |Price | ------------------------|-----------|-------|---|------| Desktop |10 |100 |+1 |$500 | Laptop |8 |50 |0 |$500 | Pocket-Size |6 |25 |-2 |$500 | Computer Upgrade |Price | ------------------------------------------------|------| +1 KNO |$50 | +2 KNO |$65 | +3 KNO |$100 | +4 KNO |$125 | +5 KNO |$200 | +6 KNO |$250 | +7 KNO |$400 | +8 KNO |$500 | +9 KNO |$800 | +10 KNO |$1000 | +5 Memory, upto double base |$2 | Computers Hardware add-ons |Price | ------------------------------------------------|---------| Keyboard & Monitor (+1 UI ) |$200 | VR Interface (+3 UI) |$1000 | B&W Printer |$300 | Color Printer |$500 | Document & Image Scanner |$200 | Speakers, Microphone & Audio Interface |$100 | Pointing device, game pad, tablet, etc. |$40 each | Network Interface/Modem |$50 | Wireless Interface |$150 | Barcode reader |$40 | TV/Video interface |$200 | 3D output mill |$3000 | Digital picture camera |$100 | Removable media drive |$40 | Disk (10 Units) |$1 | Disk (100 Units) |$15 | Disk (300 Units) |$50 | ### Moore's Law Moore's Law, which strictly speaking predicts the rate of improvement of transistor performance, has been generally applied to computer technology as every 18 months, computer power doubles. In game terms, this is reflected by every 18 months a computer gets -2 to it's KNO. So expect to buy a new computer every 18 months if you want to stay on top of the game. The GM may extend this penalty to any other high tech item, such as anything having to do with data transfer speeds. ## Software Power Stability Program |Cost |Memory | ------------------------------------------------|-------|-------| **OS** | | | Embedded OS (Forth, DOS) | | | Server OS (Unix) | | | User OS (Mac OS) | | | **Productivity** | | | Document Editing |$3 |1 | Each page of Document |- |1 | Audio Editing |$3 |1 | Each 15s of Audio |- |1 | Video Editing |$3 |1 | Each 15s of Video |- |4 | Data Storage | | | **Tools** | | | Control Logic | | | Multitasking | | | Games | | | Simulation | | | Tracing | | | Network Security | | | Intrusion |$3 |1 | Decryption |$3 |1 | Compression |$3 |1 | Encryption |$3 |1 | Mathematics |$3 |1 | Game: specific |$1 |2 | Simulation: specific |$3 |2 | Design: specific |$5 |2 | Knowledge Base: specific |$3 |2 | Financing |$3 |1 | Trace |$3 |1 | Restore |$3 |1 | Security |$3 |1 | Intrusion Detection |$3 |1 | Computer Skills/Programs(1-64) | | | Cryptography | | | Virus | | | Worm | | | Action | | | Robot | | | Data search | | | Security | | | Simulation | | | AI | | | ### Programming #### Modifying Software #### Open Source ## AI Computers can be used as mental characters that can be programmed to act on there own, but they cannot initiate there own actions, use there extensive knowledge to deduce things, or refuse properly formatted requests. To get around this a computer may fake these by being programmed with an artificial intelligence.

Choose circuit modules and connect data streams and signals to get the effect desired. Total the cost of the components and use the table to determine the DC based on module count. Power supplied by the supply must exceed what is used by the modules. Size is the same as the largest module, with the following important addendum. Any two modules with the same size count as one module one size larger. If we had 1 module size 1, 2 modules size 2, 1 module size 3 and 1 module size 4, that would be the same as 1 module size 1 and 1 module size 5 so the whole project would be size 5. if you dropped the size 2, 3, or 4 module then the project size would be 4. If you had 15 modules size 2 that is the same as 1 module size 2, 1 module size 3, 1 module size 4 and 1 module size 5, so the whole project is size 5. Devices with advanced control logic will require software to run. The Base DC is 25 if written by the same person who built the hardware. The DC goes upto 30 for a third party SW developer. the HW developer can make an aid another check, using Assisting, Craft: Programs or Craft: Digital Electronics. **Examples** * Active night vision ($65, DC 27) * Screen, Low Res * IR Camera, Low Res * Bright IR light * Calculator ( $25, DC 27) * Simple Math Chip * Keypad * Numerical Display Modules |DC | --------|---| 2 |25 | 4 |27 | 8 |29 | 16 |31 | 32 |33 | 64 |35 | ### Chips And Circuit Modules Module |DC |Size |Power |Cost | | ---------------------------------------|----|-----|------|-----|----------------------------------------------------------------------------------------------------| **Logic** | | | | | | Delay chip | | | |$1 | generates a signal a fixed time after starting | Clock | | | |$1 | generates a signal every fixed period of time | Clock/calender | | | |$5 | reports current time and date | Counter | |1 | |$1 | reports count of signals | Control Toggle | | | |$1 | generates a signal when reported data stream crosses a preset threshold | Amplifier chip | | | |$5 | reports an amplified version of another reported data stream | Simple math chip | | | |$10 | performs simple mathmatical calulations | **Advanced Logic** | | | | | | Programmable logic device | | | |$40 | programmable collection of logic devices, can be programmed with Craft: Digital Electronics | Embedded CPU | | | |$150 | KNO 6 | Portable CPU | | | |$200 | KNO 8 | Full CPU | | | |$250 | KNO 10 | **Storage** | | | | | | Memory per unit | | | |$2 | | Read only memory per unit | | | |$1 | | **Inputs** | | | | | | Button or switch | | | |$1 | generates a signal on user action | Keypad | | | |$5 | array of 20 buttons | Keyboard | | | |$20 | array of 100 buttons | External port | | | |$5 | external connection for data or signals | - cable per yard | | | |$1 | | **Displays** | | | | | | Indicator light | | | |$1 | signal causes display for the user | Bar graph display | | | |$3 | array of 8 indicators for displaying a multi-level signal | Numerical display | | | |$10 | display of 10 digit numbers | Alphanumerical display | | | |$30 | display of 80 letters, digits or punctuation | Low Resolution screen | | | |$50 | -2 to Notice Sight | High Resolution screen | | | |$200 | | External display controller | | | |$40 | external connection to display device TV, monitor, etc | **Sensors** | | | | | | Flow speed detector | | | |$15 | reports fluid (gas or liquid) flow rate | Specific fluid detector chip | | | |$10 | reports concentration of fluid | Temperature detector | | | |$5 | reports temperature | pressure detector | | | |$10 | reports pressure guage | Geiger detector chip | | | |$20 | reports radiation (alpha, beta or gamma) levels | **Position Time Sensors** | | | | | | GPS reciever | | | |$20 | reports time and position based on satellite broadcasts | Altitude detector | | | |$10 | reports altitude based on air pressure | Depth detector | | | |$10 | reports depth based on water pressure | Gyro-compass | | | |$45 | reports heading relative to north and an artificial horizon | Accelerometer | | | |$10 | reports ???
