The Powers/Remington Rand card format was initially the same as Hollerith's; 45 columns and round holes. In 1930, Remington Rand leap-frogged IBM's 80 column format from 1928 by coding two characters in each of the 45 columns – producing what is now commonly called the 90-column card. [31] :142 There are two sets of six rows across each card. The rows in each set are labeled 0, 1/2, 3/4, 5/6, 7/8 and 9. The even numbers in a pair are formed by combining that punch with a 9 punch. Alphabetic and special characters use 3 or more punches.

Rounded corners, hole punching, die cutting If you are aiming for performance oriented animation, or more sophisticated feature film animation in the Disney tradition, you will need the canvas size that 16 field offers you. This will become obvious to you as you progress. When starting out with basic exercises, 12 field is enough. However as you progress, you may feel restricted and that you need more space to draw. 12 field will eventually become quite limited, especially when handling acting, lip sync, and complex performance.

The tapes the NSA creates contain cryptographic keys or seed values for cryptography algorithms. These were distributed to whoever required them—such as the UK’s General Communications Headquarters (GCHQ)—in tamper-proof plastic containers. You have to destroy the container to remove the tape so it is obvious if the key or seed value is compromised.With a parity bit, on an eight-hole tape, you have seven bits to encode with. 1111111 in binary is 127 in decimal, meaning you have 128 different codes that can be punched into the tape—if you take 0000000 as the first code. These codes can be assigned to binary data values, op-codes, or they could be assigned to values representing letters.

The tougher you make the paper the more you reduce its flexibility. Some paper tapes I’ve seen employed quite a heavyweight paper with a waxy finish in an effort to make them more robust and at least a little waterproof. Some of the more expensive paper tapes were actually a sandwich of paper, a stretched polyester film, and paper. Where Did Punched Paper Tapes Come From? Acid-free paper or Mylar tapes can be read many decades after manufacture, in contrast with magnetic tape that can deteriorate and become unreadable with time. The hole patterns of punched tape can be decoded by eye if necessary, and even editing of a tape is possible by manual cutting and splicing. Unlike magnetic tape, magnetic fields such as produced by electric motors cannot alter the punched data. [15] In cryptography applications, a punched tape used to distribute a key can be rapidly and completely destroyed by burning, preventing the key from falling into the hands of an enemy.

The Univac UNITYPER introduced magnetic tape for data entry in the 1950s. During the 1960s, the punched card was gradually replaced as the primary means for data storage by magnetic tape, as better, more capable computers became available. Mohawk Data Sciences introduced a magnetic tape encoder in 1965, a system marketed as a keypunch replacement which was somewhat successful. Punched cards were still commonly used for entering both data and computer programs until the mid-1980s when the combination of lower cost magnetic disk storage, and affordable interactive terminals on less expensive minicomputers made punched cards obsolete for these roles as well. [31] :151 However, their influence lives on through many standard conventions and file formats. The terminals that replaced the punched cards, the IBM 3270 for example, displayed 80 columns of text in text mode, for compatibility with existing software. Some programs still operate on the convention of 80 text columns, although fewer and fewer do as newer systems employ graphical user interfaces with variable-width type fonts. The British Powers-Samas company used a variety of card formats for their unit record equipment. They began with 45 columns and round holes. Later 36, 40 and 65 column cards were provided. A 130 column card was also available – formed by dividing the card into two rows, each row with 65 columns and each character space with 5 punch positions. A 21 column card was comparable to the IBM Stub card. [53] :47–51 Mark sense format [ edit ] HP Educational Basic optical mark-reader card. In the 1970s, computer-aided manufacturing equipment often used paper tape. A paper tape reader was smaller and less expensive than Hollerith card or magnetic tape readers, and the medium was reasonably reliable in a manufacturing environment. Paper tape was an important storage medium for computer-controlled wire-wrap machines, for example. a b Aspray, William [in German], ed. (1990). Computing before Computers. Iowa State University Press. pp.142, 151. ISBN 978-0-8138-0047-9. Perforated paper tapes were first used by Basile Bouchon in 1725 to control looms. However, the paper tapes were expensive to create, fragile, and difficult to repair. By 1801, Joseph Marie Jacquard had developed machines to create paper tapes by tying punched cards in a sequence for Jacquard looms. The resulting paper tape, also called a "chain of cards", was stronger and simpler both to create and to repair. This led to the concept of communicating data not as a stream of individual cards, but as one "continuous card" (or tape). Paper tapes constructed from punched cards were widely used throughout the 19th century for controlling looms. Many professional embroidery operations still refer to those individuals who create the designs and machine patterns as punchers even though punched cards and paper tape were eventually phased out in the 1990s.

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. In 1846, Alexander Bain used punched tape to send telegrams. This technology was adopted by Charles Wheatstone in 1857 for the Wheatstone system used for the automated preparation, storage and transmission of data in telegraphy.

Detailed description of two paper tape code systems, Baudot code and the system used by the ILLIAC computer Rarely would the computers of this period use plain ASCII, even though that standard had been available from 1967. It wasn’t even possible to encode ASCII on five-hole tapes. These were restricted to a very limited character set, and capital letters only. Even with an eight-hole tape, each manufacturer would add their own twist to the encoding, so pure ASCII was a scarcity.
