Product Information

How much tooth or smoothness? This can depend on your drawing materials. The higher quality paper that is made specifically for animation usually has one side that is a little smoother, and another side that has a bit more tooth (rough texture) to it. Depending on the drawing materials** you use (how waxy or chalky your drawing pencils are), you may prefer the smooth side or you may prefer the toothier side. I appreciate that about quality paper, I like being able to have the option that works best with the pencils I’m using. Artist and architect Maya Lin in 2004 designed a public art installation at Ohio University, titled "Input", that looks like a punched card from the air. [78] Lubar, Steven (1993). InfoCulture: The Smithsonian Book of Information Age Inventions. Houghton Mifflin. p. 302. ISBN 978-0-395-57042-5. Paper tape could be read into computers at up to 1,000 characters per second. [8] In 1963, a Danish company called Regnecentralen introduced a paper tape reader called RC2000 that could read 2,000 characters per second; later they increased the speed further, up to 2,500cps. As early as World War II, the Heath Robinson tape reader, used by Allied codebreakers, was capable of 2,000cps while Colossus could run at 5,000cps using an optical tape reader designed by Arnold Lynch. The idea of control and data storage via punched holes was developed independently on several occasions in the modern period. In most cases there is no evidence that each of the inventors was aware of the earlier work.

In the case of cryptographic keys, the inherent flammability (sometimes enhanced by using flash paper) of paper tape was an asset. Once the key had been loaded into the device, the paper tape could simply be burned, preventing the key from falling into enemy hands. Winter, Dik T. "90-column Punched Card Code".

The variable-length card feed feature on the 24 or 26 allows the processing of 51-, 60-, 66-, and 80-column cards (Figure 20) ISO 6586:1980 Data processing – Implementation of the ISO 7- bit and 8- bit coded character sets on punched cards. Defines ISO 7-bit and 8-bit character sets on punched cards as well as the representation of 7-bit and 8-bit combinations on 12-row punched cards. Derived from, and compatible with, the Hollerith Code, ensuring compatibility with existing punched card files. Semyon Korsakov was reputedly the first to propose punched cards in informatics for information store and search. Korsakov announced his new method and machines in September 1832. [8] In 1931, IBM began introducing upper-case letters and special characters (Powers-Samas had developed the first commercial alphabetic punched card representation in 1921). [56] [57] [nb 1] The 26 letters have two punches (zone [12,11,0] + digit [1–9]). The languages of Germany, Sweden, Denmark, Norway, Spain, Portugal and Finland require up to three additional letters; their punching is not shown here. [58] :88–90 Most special characters have two or three punches (zone [12,11,0, or none] + digit [2–7] + 8); a few special characters were exceptions: "&" is 12 only, "-" is 11 only, and "/" is 0 + 1). The Space character has no punches. [58] :38 The information represented in a column by a combination of zones [12, 11, 0] and digits [0–9] is dependent on the use of that column. For example, the combination "12-1" is the letter "A" in an alphabetic column, a plus signed digit "1" in a signed numeric column, or an unsigned digit "1" in a column where the "12" has some other use. The introduction of EBCDIC in 1964 defined columns with as many as six punches (zones [12,11,0,8,9] + digit [1–7]). IBM and other manufacturers used many different 80-column card character encodings. [59] [60] A 1969 American National Standard defined the punches for 128 characters and was named the Hollerith Punched Card Code (often referred to simply as Hollerith Card Code), honoring Hollerith. [58] :7 Binary punched card.Suitable for high volume printing, faxing and copying, the 500 sheets of A4 business paper give exceptional reliability when used in high-speed laser and colour inkjet printers as well as copier machines. The NSA is phasing out paper tapes and will do so within 12 months. The final production run is going to happen this year. At their peak use, the NSA was creating millions of paper tapes per year. They were having it delivered in 5000 feet rolls—that’s almost a mile (1.5 kilometers)! Some suppliers offer a mid tier standard quality of paper. It is not made for high end professional use, but it is still reliable in most cases and good for lower end productions or student work. Paper tape could be read into computers at up to 1,000 characters per second.
