STC Cogitators (RAM)


Secrets of origin of the cogitators are lost in turmoils of age of strife. This STC template dominates Imperial computational technology. It is probable that Noospheric Space, cogitators and datacubes were the foundation of an artificial intelligence developed during the Dark Age of Technology 

There are two cogitator templates, a mechanical and a digital:
-Mechanical are reliable, slow, cumbersome, single task oriented.
-Digital are delicate, fast, small, intricate and multi task oriented.

Common Imperial portable cogitator devices

Calculance Array, Scarce, Rogue Trader corebook page 144
“Grand mercantile initiatives are attended by a swarm of scribes and ledgers, and the greatest can only thrive when supported by machines such as the calculance array. It is a noisy, man-sized stack of chugging, promethium-fueled rod-cogitators, often mounted upon a tracked platform. Its machine spirit accepts reams of figures, and other data, ordering them and spitting forth parchment summations and predictions upon command.
It provides a +10 bonus to all Commerce Skill Tests.”
Components: Mechanical cogitator, mechanical display, requires power source

Hadd-pattern Dataloom, Very rare, Rogue Trader corebook page 144, Ravenor chapter?
“A limited data-engine and geometric display that has proven useful to those faced with challenging problems of logic or fragmentary information. It gives a +10 bonus to Logic skill Tests, and at the GM’s discretion may reduce the time taken for research or investigations, provided that the investigator has the Tech-Use skill.”
-Datalooms can be stacked together to increase performance. 4 Datalooms are able to handle information flow of a standard Imperial system, 30 data-looms can handle information flow of a sector and with 64 tainted looms you can decipher secrets of the Warp.
Components: Digital cogitator, MIU interface, Display, requires power source

Remuneration Engine, Very Rare, Rogue Trader corebook , page 146
“A tool and symbol of status for wealthy factors and brokers, the optics and prongs of this heavy device rapidly stack, count, and assay the worth of diverse currencies.
Any attempt to cheat by Sleight of Hand or similar method of distraction suffers a -30 penalty where a Remuneration Engine is used. Its temperamental machine spirit requires the constant attention of tech-adepts, however.”
Components: Mechanical cogitator, mechanical display, sensor, power cell

Locke-pattern Long-range Auspex, Very Rare, Into The Storm, page 136
“This is a larger and more powerful version of the hand-held auspex devices used by Imperial agents, usually mounted on a large, transportable chassis for added stability. Though bulky, it can scan huge areas of terrain as well as the sky above and the ground below to detect movement patterns, vox signals, seismic disturbances, and other programmed criteria. Its onboard cogitators analyse and display detected information. The Long-range Auspex counts as an Auspex in all respects, save its range is 5 kilometres and it can penetrate walls up to a metre thick. Good Craftsmanship versions increase the range to 10 kilometres, and Best versions grant a +30 to Awareness Tests made with the device, instead.”
Components: Digital cogitator, sensors, display, power cell

Diagnostor, Rare, Rogue Trader corebook page 144
“The diagnostor is a sophisticated medical device used among high ranking planetary officials and other powerful individuals. It can detect and diagnose almost every ailment known to the Imperium, and can be incorporated into medical kits, servo-skulls, and other dedicated servitors. Rogue Traders who are often away from proper medical assistance feel that such devices are essential on their voyages.
A Diagnostor provides +20 to Medicae or Perception Tests to determine an ailment. Any success indicates the proper medical countermeasures.”
Components: Digital cogitator, sensor, digital display, power cell

Ocular Catechizer, Inquisitor’s Handbook, page 127
“A device favoured by ranking adepts, sages and Administratum officials, these arcane and intricate-looking eyepieces are designed to magnify objects and help identify
and analyse visual patterns and data. They are somewhat temperamental instruments, requiring stillness and concentration to use; their machine-spirits are notoriously
easily vexed, much to the pain of the operator.
Using these devices gains a character a +10 bonus on Literacy, Lore and Search Tests where the close examination of objects, symbols and deciphering written
text is involved. Other Actions cannot be attempted while using an ocular, and if a failure by four or more degrees is rolled on a Test involving the device, feedback through
the eyepiece inflicts 1 level of Fatigue on the user. The eyepiece can also record its impressions to an attached data-slate for later study.”
Components: Digital cogitator, sensor, miniature display, power cell

Calculus Logi Upgrade, Dark Heresy 2, page 182
“These bionics are internal cogitator implants which aid in data retention and processing. The user can rapidly sift through stacked dataslates and parchments, applying intuition to vast reams of data far beyond the capabilities of a normal man. This implant grants the user a +10 bonus to Literacy, Logic, and Scholastic Lore tests.”
Components: Mechanical/digital cogitator, cybernetic,

Locator Matrix, Dark Heresy 2, page 183
“Micro-cogitators implanted at the base of the skull allow the user to be aware of the direction of the planetary poles, the Acolyte’s present location to within a few meters, relative velocity, altitude, time of day, and other valuable information. The user must still have access to maps and other planetary data in order to benefit from this information, however—knowing one is at a specific location on a planetary surface has little meaning without knowing what is over the next rise, or what is the direction needed to reach a given destination.”
Components: Digital cogitator, sensor, cybernetic

Poi-Savant, Inquisitor Handbook page 153
Spending time in xeno environments means that sooner or later one will have to sample the “local” cuisine, which may not resemble anything one is used to. Indeed, some travelers try to opt for a plant or creature that has a “familiar” appearance, but this is no less dangerous—for the assumption that a given thing must be safe to eat based on resemblance is a foolhardy one. Enter the poi-savant. A hand-held cogitation device, the poi-savant measures various levels of bio-chemicals and searches for signs of a diverse number of dangerous toxins in any substance that it is used to analyze. Any substance the poi-savant clears as “edible” is safe for human consumption, though not necessarily appetizing.
Originally applied on Malfi, where the noble houses even now use them at every meal, poi-savants tend to be remarkably accurate devices as they have had well over a thousand years of field-testing. Indeed, many Malfian nobles make a point of commissioning their own personally tailored poi-savant, generally by miniaturizing them into elegant wands or ornate rings that they can simply pass over their meals without appearing unduly concerned (or rude).
Personal poi-savants must be updated regularly as new toxins are identified, leading to an ongoing race between their cogitators and the cunning of the countless assassins who constantly seek out new poisons in the hope that they will thwart their target’s poi-savant. Poi-savants were specifically
designed to be easy to use; their operator need only make a Routine (+20) Tech-Use Test to employ them correctly.
A failed Test gives inconclusive readings, while a failure by three or more degrees indicates that a blameless substance is toxic or vice versa (GM decision).
Components: Sensor, digital cogitator, display, power cell

Cogitator System, Inquisitor’s Handbook page 146
“Machines created to sift and consider data, to calculate and to process the sacred language of algorithm, these devices range from small portable models to larger logos tabernacles and matriculation-engines integrated into manufactora, star ships and archive centres.
Using a suitable cogitator grants a bonus on Literacy, Logic and Lore Tests when having to compare or sift through large volumes of data.

These cogitator systems analyze and process vast quantities of data (planetary tithe records, genotype reconstructions, and so on). Most also feature auto-quills to print data-scrolls, machine-spirit shrines and symbiotic operations-savants or holo-projectors incorporated into their structure. They grant a +20 bonus on relevant Tests. Proper rites and rituals must be observed during cogitator operations on this scale or they will become subject to severe inaccuracies and glitches, perhaps even possession by malign spirits.
Components: Digital or mechanical cogitator, power cell, MIU, touch display

These portable units are capable of analyzing the information from data-slates and similar sources, and provide a +10 bonus on relevant Tests.”
-Can be mechanical (cumbersome, slow, reliable) or digital (small, fast, fragile).
-Used to analyze information stored to imperial data-storage. May be specialized to certain areas of information on cost of variety of information. Bonuses and penalties up to GM, but rule of thumb +5 specialized bonus bringas -5 to other topics.
Components: Digital cogitator, power cell, MIU, touch display

Void Abacus, Into The Storm page 140
“While the search for priceless archeotech is one of the most profitable endeavours a Rogue Trader can undertake, there are those who dedicate their lives to the suppression and elimination of many wondrous items from the Dark Age of Technology. One such item sought after by both camps is the Void Abacus, most famously unearthed on the cursed Munitorum planet of Soloman in the Markayn Marches but also recovered in the bowels of many an ancient hive spire or nameless space hulk. For these can do something very valuable indeed—when integrated into a ship’s auspex and propulsion systems they can allow a ship to make accurate void jumps four or five times longer than normal without a Navigator’s aid. This allows many more types of ships to travel safely, something the Navigator’s Guild cannot allow. While the Guild cannot directly outlaw their use, they can act to buy, destroy, or sabotage any and all they can find.
That they will arrange for the same fate to befall to any vessel found using one is an open secret as well. Having an Abacus networked into a ship’s systems allows the crew to safely plot warp jumps of up to 5-10 days in duration with an Ordinary (+10) Navigation Test.”

Cogitator Interlink Pow: 1 Space: 1 Extremely rare, Into The Storm, page 161
“Though the creation of true artificial intelligence is one of the darkest heresies of the Adeptus Mechanicus, this was not always so. The Men of Iron were the most infamous example of such technology, but the Dark Age of Technology generated many others. The cogitator interlink is designed to amplify the starship’s core cogitator, enhancing the ship’s operations considerably.
Sophisticated cogitation operation: This starship’s Crew Rating gains a +5 bonus.
-The ancient cogitator interlink is designed to amplify bandwidth between the starship’s drive’s cogitator and cogitators distributed among other components, enhancing the ship’s operations considerably.

Administratorial vault

Teleskopeian Shrine


Temple of Knowledge  Space: 5, Power: 5, Ship Points 10, Archeotech, edited for Ultima Tectum campaign
Appropriate hull type: Can only be put in a Habitat, Heavy Frigate, sufficiently sized Transport (Space and Hull both of at least 40), Light Cruiser, Cruiser, or Larger ship.
This Temple is a fantastic piece of archeotech and engineering, kept lovingly updated by some of the most powerful members of the Imperium, placing what would normally be many more components, usually spread throughout a fleet in anything other than an Ark Mechanicus, so that a single ship can usefully do a myriad tasks befitting exploration and the obtaining of knowledge.

 It has a myriad linked components:

  • A Shrine of the Emperor in his guise of the guiding light of human knowledge, or as his incarnation as the Omnissiah, as well as various Imperial saints associated with blessings of sanctioned, appropriate individuals towards tasks of learning and discovery for the greater humanity.
  • A Librarium where, rather than being stocked mainly with books and scrolls, writings can be etched microscopically onto durable disks of sapphire or diamantine for later storage and retrieval, including facilities necessary to transfer traditional media onto this method.
  • A Laboratorium, where small artefacts can be studied.
  • A small-batch rapid prototyping Manufactorum, with the curious, lost-to-time name of a ‘Skunkworks’.
  • A small research Hospital where humans can be treated or ailments investigated or upgrades installed to the flesh.

Some of the capabilities are less compared to their larger, dedicated equivalents, but the sheer usefulness more than make up for it.
+10 bonus to crafting or repair checks of small items or small batches of items, including via Trade checks, as well as medicae tests, all non forbidden lore investigation tests, as well as forbidden lore archeotech, and, at GM’s discretion, any forbidden lores directly associated with sanctioned Imperial technology, like Mechanicum, Astartes, Ecclessiarchy, or Inquisition (when dealing with Mechanicum/Space Marine/Sororitas/Inquisitorial technology, for example).
Further, at GM discretion, sometimes extended actions such as Triage may work for more crew than otherwise when making use of this component, and other similar benefits.
Counts as having Good Quality Superior Damage Control for this component only, even if that component and upgrade are not otherwise on the ship.
Cannot be made Best Quality; is already Archeotech *+25 to all endeavors due to the multi-faceted utility.
