 Item number SCP-1875 Object Class, Euclid Next Scheduled November 77 Exercise In Progress Correction, Cancelled Authorized Personnel Only Access Granted Explanation of recent containment procedure changes. We believe that computer networks at SCP-1875's holding site have been compromised. As a result, all electronic communications with the facility have been severed depending further notice. Overwatch headquarters has declared a moratorium on future November 77 exercises until such a time as we fully understand how 1875 transmits and receives wireless communications signals. Accordingly, I have amended these procedures with two clauses regarding number one, exposure of SCP-1875 to wireless data networks and number two, treatment of individuals exposed to 1875 image 1AB. O5 Special Containment Procedures SCP-1875 must never come within transmission range of any wireless data network. The machine's container must be enclosed by a Faraday cage and it must have a fully mechanical locking mechanism. The holding site's full-time staff must include at least two network security experts, one armed security guard, and one child psychology specialist. When the machine is fully assembled and activated, the speed adjustment lever on SCP-1875-3 may not be set to 5, which is the maximum speed, without direct supervision by the site's level 4 supervisor. Electronic devices with data storage capacity may not be introduced to the facility, except during exercise 1875-November 77. Correction. See further documentation. And all individuals must be screened for such devices prior to entering the holding site. In the event of exercise 1875-November 77, Overwatch headquarters will permit one designated and clearly marked laptop computer to be taken into SCP-1875's primary shielded container. Upon completion of November 77, facility staff must ensure this designated laptop is shredded in the facility's scrap metal shredder. Correction. Research data may only be removed from the container in the form of a paper printout. Any evidence of 1875-Image-1AB exposure must be reported immediately to Overwatch headquarters. Description. SCP-1875 is a Victorian-era chest automaton, consisting of four principal components, hereafter referred to as SCP-1875-1, SCP-1875-2, SCP-1875-3, and SCP-1875-4. SCP-1875-1. View Image. Access Granted. A steel chessboard table, 72 x 72 x 64 cm, with a standard 8 x 8 grid of 64 checkered squares painted on its surface. Based on its composition and patina, research staff have identified the exact material as English crucible steel, likely cast between 1820 and 1870 on 1990. Mobile Task Force retrieved SCP-1875 from an abandoned laboratory facility discovered beneath the former residence of University Professor in Shire, England. A driveshaft designed to connect with SCP-1875-3 protrudes from one side of the system's otherwise seamless enclosure. The table contains a sophisticated mechanical and biological system that controls a matrix of 64 electromagnets using an analytical engine composed of the combined brain tissue of the twin daughters, designated SCP-1875-1a and 1b, of Russian chess prodigy each square on the chessboard surface sits above a single electromagnet, and each electromagnet can move one chess piece to one of eight neighboring squares. Researchers have developed several theories regarding the control mechanism's functional specifications, but the nature of its biological component and possible sentience remain unverified. SCP-1875-2 A complete set of 32 chess pieces carved in the oriental style from human bone. Each piece is affixed with a thin .31 centimeter base pad of ferromagnetic iron. Samples of the bone used for the pieces have been matched genetically with tissue samples from SCP-1875-1a and SCP-1875-1b. Following the recovery of SCP-1875-1, an anonymous individual associated with Professor B. S. A. State submitted information to Foundation personnel regarding these chess pieces, leading to their subsequent discovery in the possession of in New York City's Washington Square Park. SCP-1875-3 View Image. Access Granted. A stationary steam engine manufactured by Maud's Lays, Sons and Field, circa 1840. Also acquired from the estate of Professor B. and designed to spin SCP-1875-1's driveshaft. The engine has been modified from factory stock to allow speed adjustments. It has five speed settings labeled in Roman numerals. SCP-1875-4 View Image. Access Granted. A suit of 18th century samurai armor in the Gusoku style arrived in storage case with SCP-1875-3, courtesy of Professor B. S. A. State. Historical evidence suggests that SCP-1875-4 would have been situated on a chair beside the chess table, serving as a performance prop. Staff have not observed any objectively unusual activities. However, several visiting researchers have reported prolonged feelings of anxiety after making eye contact with the armor's faceplate. Addendum 01. Intake Reports. Authorized personnel only. Access Granted. SCP-1875-4 Personnel Involved. Intake Analyst. Date. 1990 Location. Site. Description. SCP-1875 appears to be a fully mechanical chess-playing machine from the mid-19th century. Correction. See further documentation. Unlike other early mechanical chess devices, see Standage Tom, The Turk, the life and times of the famous 18th century chess-playing machine, SCP-1875 does not appear to be designed to conceal a human operator within its case. SCP-1875 was built for the same purpose as contemporaneous devices, as a traveling curiosity designed to be played by volunteers before a group of spectators who would be charged an admission fee. Identities of several of the machine's previous owners are known. See. But reliable information regarding its original designers and fabricators remains elusive. When questioned about the origin of SCP-1875, a representative from the estate of Professor directed us to a Russian newspaper clipping. See. Found among the professor's belongings. The article concerns the disappearance of the twin 14-year-old daughters of Russian chess champion on 18. Subsequent historical records indicate that the girls were never found and that Russian authorities failed to identify the person's responsible. However, we have yet to establish any connection between these events and SCP-1875. Correction. See further documentation. Evidence of the machine's public appearances beginning in 18 under the name The Samurai have been found in Russian, British, and American newspaper archives. See. The last recorded appearance of The Samurai occurred on April 1906 in San Francisco, California. Its owner at the time, sideshow proprietor, Mr. perished in the aftermath of the earthquake that struck San Francisco later that month. SCP-1875 was presumed to have been destroyed as well until its recent discovery by the Foundation. After assembling the components of SCP-1875 at the site intake facility, we have begun testing the device for anomalous properties. Addendum 02. Incident 1875-55A Authorized personnel only. Access granted. Source 1875- inbox archive. File 1875- from 1875- department research director to DEL 1875. Subject regarding test 1875-55. Date. 1177-1999. Correction. 1107-1999. Time code 1658. Upon complete assembly, it was confirmed that SCP-1875 chess hardware is fully operational. In this test, a modern chess computer with variable strength software was used to measure SCP-1875's analytical intelligence. We positioned one member of class D personnel 1875-D1 in containment with the machine seated behind the chess board's black side and facing 1875-4, which we positioned behind the white side. Five chess games were played, one on each of the steam engine's speed settings. Instructions were provided through wireless speakers from behind plexiglass shielding to move each piece. 1875-D1 remained unharmed and returned to site for next assignment. Here's a quick list of the chess strength at each setting as estimated on the ELU rating system. We're confident about the numbers measured on settings 1-4. Setting 1. 800-1000 ELU. Setting 2. 1000-1200 ELU. Setting 3. 1200-2500 ELU. Setting 4. 2500-... ELU. Setting 5. 0-... See additional notes. Test on setting 5 remained the outlier, and so we performed additional tests with chess-proficient researchers. See file 1875-V games through initially, SCP-1875 exceeded ELU, a % increase from the maximum rating measured in our setting 4 tests. After game, SCP-1875 chess play was marked by illogical moves. During game, illegal moves were observed, causing us to abandon games in progress. This activity was seen more frequently as testing progressed. After game, erratic piece movement was observed. The speed at which SCP-1875 moved its pieces increased, and it began to violently ram pieces together on the board. Several chess pieces were chipped, and we decided to cease testing until we can determine a way to proceed without causing more damage. Staff currently suspects that setting 5 may be malfunctioning due to excess age and wear. Five minutes later, the following list was sent to all members of the SCP-1875 email distribution list. From 1875- Research Analyst to DL1875 Subject Regarding Forward Regarding Test 1875-5 Date 1177-1999 Correction 1107-1999 Timestamp 1703 Attachment Shakmate. 17.2 megabytes So, C 3 D 4 E A N 6 N G 8 1875 Image 1AB is an image file that appeared in the body of the suspicious email above. It has been removed from this report due to unknown memetic properties, which caused an adverse reaction in personnel who unintentionally viewed it while checking email on 1107-1999 before others could be notified. The image appears to be a black-and-white photograph of two young girls, though firsthand accounts describe it as distorted, or stretched, in a visually disturbing manner. Shakmate. is an executable file, written to control subtle background movements in 1875 Image 1AB. It is theorized to drive 1875 Image 1AB's memetic effect, though researchers have yet to confirm this. The reaction to 1875 Image 1AB exposure was characterized by symptoms T plus zero exposure mild anxiety T plus 15 minutes headache, elevated body temperature T plus two hours restlessness, insomnia, auditory hallucination reported, often heard as quiet childlike laughter. T plus four hours visual hallucination reported, intense anxiety. T plus seven hours subjects remain conscious, though increasingly unresponsive to external stimuli.
