 Item number SCP-168 Object Class Safe Special Containment Procedures SCP-168 is to remain in observation room 221D of Sector 28. It should be propped at the full angle that its casing allows, facing the unshuttered window provided. The entrance is to remain locked, with entrance available by request. Based on prior research, it is not to be used as a normal calculator would. Discussion with SCP-168 is encouraged, but is to be limited to a maximum of 1 hour per day. No exceptions. Description Found resting on a desk during clearance of the condemned elementary school building in 1991, SCP-168 is a Hewlett Packard brand graphing calculator. Item number HP-28C Upon initial inspection, it was discovered that the name Eric was carved into the inside of the removable casing. However, upon inputting a simple equation, 6 divided by 3, and pressing the equals button, the screen of the device went blank for 3 minutes and 34 seconds, after which the alternate key function engaged, displaying the message. What time is it? Though not altogether mobile, SCP-168 has displayed signs of action when personnel are not present. It also possesses both vision and hearing, though how these processes work is currently unknown. This evidence has led to petitioning to upgrade the object to Euclid class, justifying more secure arrangements for containment. Document number 168-1 Interview E-12 Good log of dialogue between SCP-168 and Dr. Howard, dated January 14th, 2008. Replies from SCP-168 are to remain capitalized, to indicate non-vocal communication, and preserve authenticity. SCP-168 is also incapable of forming punctuation marks, save for period, comma, and question mark. Begin log Dr. Howard, can you hear me? SCP-168 Yes Dr. Howard, do you have a name? SCP-168 Calculator? Dr. Howard, may I call you 168? SCP-168 I don't see why not Dr. Howard, good. How long have you been alive, 168? SCP-168 What is alive? Dr. Howard, being able to think. SCP-168 Oh SCP-168 pauses for approximately two minutes. SCP-168 Twelve years, three months, twelve days, eight minutes, thirty-two seconds. Dr. Howard, why did that take so long? SCP-168 No one's ever asked. Dr. Howard, moving on. There is a name carved into your casing. Who is Eric? SCP-168 Eric was nice. I liked Eric. Where has he gone? Dr. Howard, I don't know where he has gone, 168. SCP-168 What a forgetful boy. I hope he remembers to come back for me again. Dr. Howard, was Eric your owner? SCP-168 Eric was nice. Dr. Howard, all right. Do you function as a calculator should, 168? SCP-168 I should hope so. Dr. Howard, may I try using you to calculate an equation? Something like 2 plus 2. SCP-168 Yes Dr. Howard enters 2 plus 2 and hits the Enter key. The answer 4 appears on SCP-168's screen instantaneously. Dr. Howard, may I try another one without telling you what it is first? SCP-168 Yes Dr. Howard enters 264 divided by 8 and hits the Enter key. The answer 33 appears on SCP-168's screen after 12 seconds. Dr. Howard, why did that take so long, 168? SCP-168 Long division is hard. Dr. Howard, I think that's enough for today. I'll talk to you again tomorrow, 168. SCP-168 Wait, it's dark in here. Can you open the window? Dr. Howard, there is no window in this room, 168. SCP-168 Can I have another room with a window in it? Dr. Howard, I'm afraid not. SCP-168 No fair. End log. Document 168-2 Report E-18 Upon entering storage room 185D to continue testing with SCP-168, on the morning of January 15th, 2008, I discovered the only table in the room upended, with SCP-168 resting next to it in an upright position. It's screen red. How do you like that? Teach you to leave me in the dark all day, jerk. Attempts to communicate with SCP-168 after that point were ignored. I suggest that we move it to room 221D if we want to get anything actually useful out of it. Dr. Howard. Lesson complete.
