Wireless communicators have Signal and Sensitivity scores. The difficulty of receiving a transmission is the range score between the transmitter and receiver minus the Signal score of the transmitter minus the Sensitivity score of the receiver.

  • Comm Wormhole Link: A plug-in adapter that fits in most phones, containing one end of a comm wormhole. The other end typically connects to a base station for access to the planet-wide network. An alternative is a secure phone-to-phone link that connects to only one other device, or to a local network, for greater data security. Comm wormholes allow communication over any range, are not affected by interference, and broadcast no signals that can be intercepted. It is illegal to cross to another world with a comm wormhole end, or to possess a comm wormhole that connects to another world.

Computer Processors

Computers are rated by their Compute scores, an aggregate score combining aspects of the computer's raw speed, parallelization, memory, and qubit register size. A computer can run software in a timely fashion whose Compute scores when ⊕-ed together do not exceed the computer's Compute score. If it tries to run more software than this the computer will run much slower, no longer being able to keep up with the software demands. While this can be acceptable for some applications, it should be avoided for any software designed to run in real-time (and can be aggravating even when this isn't the case).

  • Hand Computer: A handheld computer similar to a modern smartphone. It includes all the capabilities of a phone, allowing it to wirelessly send and receive data from the network (as well as making and receiving voice and video calls). It has a built-in basic camera, magnetometer, accelerometer, clock, microphone, and speaker. A hand computer forms a control hub of personal equipment, routing information from devices to HUDs and other displays and allowing automatic control of networked devices. AI with deep learning algorithms coordinates programs and functions and interfaces with the user, as well as providing augmented reality displays if the user is equipped with an HUD-capable device. The AI coordinator will access the web to answer questions ("Were's the nearest pizza joint?") or query specialty programs not stored locally ("What's the safest path down this scree slope?"). While not strong AI (it can't think like a person, and has no personal initiative), it can significantly augment a person's natural capabilities. Nevertheless, most people primarily use their computers for making phone calls, sending messages, playing games, and browsing the web. The operating system comes standard with a web browser, office tools (spreadsheet, word processor with transcription, email and calendar organizer, and so forth), navigation software, object recognition, natural language processing, calculator, photo organizing and viewing software, and music organizing and playing software. Input and display is primitively using a holographic touchscreen on its front and voice recognition and response, but more commonly through an HUD and haptic web.

  • Laptop Computer: A portable computer that can handle more intensive computations than a hand comp. It has the same basic built-in capabilities and operating system, but is larger and its primitive input is via a much larger holographic touchscreen and keyboard, as well as natural voice communication.

    Power: 15 W
    Duration: 250 ks (3 days)
    Compute: +7
    Mass: 1.5 kg
    Price: $60

  • Desktop Computer: A computer capable of some dedicated number crunching, and with bigger and more convenient native interfaces. It has the same basic built-in capabilities and operating system as a hand comp, but runs faster and can hold more programs in memory.

    Power: 50 W
    Compute: +8
    Mass: 8 kg
    Price: $100

  • Upgrades: The basic computers listed are the low-end models of each class. True technophiles will want systems with state-of-the-art processors and memory.

  • Earbuds: Small wireless speakers that fit into the user's ears.

  • Haptic Projector: Projects the feeling of touch over a distance, allowing feedback for gesture controls.

    Mass: 0.5 kg
    Price: $40

  • Haptic Web: A mesh worn over the hands that gives the computer a kinesthetic sense of the mesh's position and provides tactile feedback to the user. Larger versions are available that cover more of the body.

  • Holographic Screen: A panel that produces three-dimensional images by controlling the amplitude and phase of the emitted light, to fully reconstruct the light's wave front. It can produce fully 3-D seeming images behind the screen, or images that appear to float in front of the screen to anyone whose line of sight to the screen passes through the image. Holographic screens can be made as thin as a sheet of paper, can be flexible so they can be bent or rolled up, and can be curved to fit on irregular surfaces.

    Mass: 0.5 kg
    Price: $8 + $10 per square meter

  • HUD: A HUD, or Heads Up Display, is a set of goggles or other eyewear that projects 3-D images in front of the user's eyes. It can sense where the eyes are looking for eye-motion control. The display is transparent where it is not producing an image. Often included as part of other eyewear.

    Mass: 0.1 kg
    Price: $8

  • Image Projector: Projects a 3-D image into free air that is not restricted by line of sight to a screen. The image is obviously artificial, appearing as a ghostly glowing shape. The projection itself comes from beams emmenating from a projector, requiring line of sight from the projector.

    Mass: 1 kg
    Price: $30

  • Inertial Simulator: Mainly used for gaming and immersive virtual reality, an inertial simulator uses a low-gradient and highly penetrating affector field to uniformly push, pull, or turn the matter within its enclosed volume. This can create the illusion of changing speed and direction or of different gravity levels, or mask actual accelerations from perception.

    Mass: 0.3 kg
    Price: $6

  • Soli-Projector: A soli-projector uses affectors to produce a three-dimensional, seemingly solid tactile and visible apparition or group of apparitions within a volume. If used with an odoricator, it can even simulate taste and smells associated with the surface.

    Price: $15 per cubic meter


HumanTech computers, GummiTech computers, and computers using designs from the Sacred Library all use different operating systems and software protocols. There are emulators and interfaces available to allow computers from one tech-line to execute programs from another; however, GummiTech and Library computers cannot perform the quantum computations that Human computers often rely on, and HumanTech computers are not as massively parallel as those of the Gummis - as an approximation, assume that running sophisticated software on the computer of a different tech line gives an effective +7 to the program's speed (simple programs, not relying on massive paralellization or quantum computation, do not suffer this problem, but they are usually sufficiently fast that this would not be an issue in any case). Some traditional Tzachiists consider it somewhere between irreverence to heresy to run an emulator or interface for other species' software on Library-design computers.
