Ibm 3890

[Kenneth Larson]

SpecialContainment Procedures: Due to the nature of SCP-3890, and my current situation, I am unable to enact containment procedures. For the time being, I will focus my efforts on exploring SCP-3890 and the anomalous phenomena it displays.

Description: SCP-3890 is a potentially extradimensional or extraterrestrial space which I, Doctor Elizabeth Graham, was somehow transported to from Site-22 on 02/17/16. At the time, I was transporting template documentation for the containment of several other SCP items, but I do not believe that they are related to this anomaly. Similarly, I am uncertain as to whether I was transported here due to my involvement with the Foundation.

In terms of geography, SCP-3890 takes the form of a seemingly infinite desert plain, with ruins of differing architectural design poking out through the sand. I have noted the presence of buildings of modern design, along with what appear to be ruins of Ancient Roman and Erikeshan structures. Exploration of these structures has shown that they are mostly empty - I am unsure whether this is by design or if they were looted at some point in the past, perhaps by a specimen of SCP-3890-1.

SCP-3890, from what I can tell, goes through a solar cycle identical to that of Earth. Perhaps this location is not extradimensional or extraterrestrial, but some location on the Earth that remains hidden, perhaps through some form of antimemetic camouflage? It's warm during the day and cold during the night nonetheless, but never to an uncomfortable degree. In that way it is very much unlike an actual desert.

Additionally, specimens of SCP-3890-1 do not defend themselves when attacked. Autopsy of one specimen has shown no differences between the anatomy of SCP-3890-1 and normal human beings. To my mind, there are two possibilities here:

So far, it appears that individuals within SCP-3890 do not experience hunger or thirst. I have been here for three days thus far, and feel pretty much the same as I did when I first arrived. I cannot be certain, however, whether I no longer need food and water or simply believe I do not. As I've come by no food here except SCP-3890-1, I very much hope the former is the case.

CHEM 3890 - CHEM 3900 is a year-long sequence covering key topics in physical chemistry. CHEM 3890 introduces the use of mathematics and physics to investigate chemical systems. The fundamental principles of quantum mechanics are introduced and applied to understanding the structure and spectra of atoms and molecules. Specific topics include exact and approximate solutions to the Schrdinger equation, angular momentum, bonding and molecules, and spectroscopy. CHEM 3900 follows with an introduction to the behavior of ensembles of quantum particles (statistical mechanics), the laws of thermodynamics, and kinetic theory.

Prior to the introduction of computers, cheque processing was performed manually by each institution. IBM recognised the opportunity to automate this processing and began a long period of building machines for this purpose, a period that started when IBM announced the IBM 801 Bank Proof machine in 1934.[1] By eliminating hand written ledgers, the IBM 801 automated teller operations.[1]

By the mid 1950s many banks began to investigate how they could use new technology to help them handle the ever growing volume of cheques that needed to be processed on a daily basis. As an example, Bank of America's checking accounts were growing at a rate of 23,000 per month and banks were being forced to close their doors by 2 p.m. to finish daily postings. Meanwhile, in the United Kingdom, wages began to be paid by cheque and the number of cheques being cleared by the central clearing house had grown from around 250 million in 1938, to around 320 million in 1951 and continued ramping up, in fact reaching over 500 million by 1964.[2]

A number of technologies were developed by companies like EMI in the UK (Figure Reading Electronic Device or FRED), and Bull in France (CMC-7) to make cheques machine readable by means of pre-printed characters or characters that were inscribed on the cheque when it was being proofed at the Branch. IBM Poughkeepsie lab under J.A. Weidenhammer meanwhile was working on developing equipment that could mechanically feed, transport and stack paper checks, because they could not be handled using existing techniques then being used with punched cards. They created a system of friction wheels and belts to achieve this.[3] Meanwhile, another group within IBM collaborated with Weidenhammer on developing a machine readable magnetic ink barcode, printed below human readable numerals, which they demonstrated to Barclays Bank in 1957.[4] But after much industry consultation, the E-13B MICR font developed by General Electric as part of a solution sold to Bank to America became the American Standard adopted by the ABA in 1958. The ABA had previously concluded that IBM's proposed marking system would be too costly and also, that it was visually unattractive. After some hesitation, IBM developed their own multi-track read head for MICR characters and switched to using E-13B.[3] In 1959 they began promoting the IBM 1210. IBM Supplies division (that also manufactured punched cards) also saw an opportunity in this period to sell paper checks, printed by IBM in an IBM Plant.[5]

IBMs main competitors in this space in 1959 were Burroughs with their B101 Reader/Sorter which could sort 1560 documents per minute, sold as part of their B251 Visible Record Computer System, and NCR who sold a sorter jointly developed with Pitney-Bowes that also used components supplied by General Electric.[6]

By 1963 the American National Standards Institute (ANSI) adopted the ABA specifications as the American Standard, along with countries like the UK, Canada and Australia. Meanwhile, CMC-7 was adopted as the French standard in 1964 and grew to be widely used in Europe and South America.[7]

Adoption of these sorters was usually linked to adoption of the Computer System it attached to, although the first 1210 rented by Barclays Bank in 1960 was used purely in an offline capacity before the Bank bought an IBM 1419 attached to an IBM 1401 in 1963.[2] Initial adoption also required new procedures and standards to be adopted, for instance Martins Bank in the UK took delivery of an IBM 1412 on 22 October 1961, but it was not fully operational till April 1963.[8]

Document processing usually involved the following process.[9] Firstly documents to be proofed would be loaded into the hopper of a proof machine and then fed through the machine one at a time. For each document:

After proofing the documents would then be sent to a reader/sorter for data capture and final sorting. The sorter may endorse the document as well as print a sequence number on the document. The sorter may also microfilm the document, while later sorters may have used document imaging technology.

Announced by IBM in July 1949, the IBM 803 is a proofing machine that could sort, list, prove and endorse checks and sort them into 32 pockets. This machine remained in the IBM Sales Manual till Dec 18, 1981.[13]

The IBM 1201 is a proof inscriber, that could perform all the functions of an IBM 803 (which it closely resembled) as well as document inscribing. It has 10 models offering a variety of options including up to 32 pockets plus document endorsing as an optional feature.[14] IBM Rochester began shipping the IBM 1201 in August 1961.[15] In 1963 IBM Supplies introduced a new endorsing roll for the IBM 1201 which can provide for up to 375,000 endorsements.[16] It was withdrawn on Nov 22, 1978.[14]

The IBM 1202 Utility Inscriber is a specially designed electric type-writer that is used to inscribe documents prior to them being sorted.[17] It was announced Jan 12, 1959 and withdrawn April 26, 1966.

The IBM 1203 is a unit inscriber that can print numerals and special symbols on documents using magnetic ink. It is also an adding machine. It was manufactured by IBM Rochester.[15] It was announced Mar 8, 1961 and withdrawn Nov 22, 1978.[14]

The IBM 1260 Electronic Inscriber was a proofing machine with eight stackers.[14] It could inscribe documents as well as optionally endorse them. Three or five external stackers could optionally be added. It was manufactured by IBM Rochester until September 1971, although it remained available for rental for many years afterwards.[19]

Announced by IBM in May 1982,[21] the IBM 4723 Finance Communication Document Processor is a small desktop reader and inscriber that attached to IBM 3600 or IBM 4700 Banking controllers using the B-Loop connection method.[10]

The IBM 1255 is a MICR reader/sorter. The IBM 1270 is an OCR reader/sorter that uses the same sorter engine as the IBM 1255 but with more processing hardware. The CMC-7 models of the IBM 1255 as well as the IBM 1270 were not offered for sale in the United States.[22][23]

Two offline sort patterns are possible but with a 6 stacker sorter, it is typical to sort in two phases. Phase one sorts on the even digits of one field (using five stackers) with odd digits going to the reject stacker (the top stacker). Phase two sorts on the odd digits of one field (using five stackers). The operator can leave the documents from phase one in the stackers when starting phase two. If a 12 stacker sorter is in use then sorting can be done in a single phase using ten stackers, with the remaining two stackers being used for rejects (using the top stacker of the first bay known as stacker R) and special sorts (using the top stacker of the second bay known as stacker A).[24]
