TRS-80 Model II
The TRS-80 Model II is a computer system launched by Tandy in October 1979, and targeted at the small-business market. It is not an upgrade of the original TRS-80 Model I, but a new system. The Model II was succeeded by the compatible TRS-80 Model 12, Model 16, Model 16B, and the Tandy 6000. Model II Background Tandy was surprised at the strong demand for the TRS-80 Model I from business purchasers. The computer was too limited for such use, so the company began development on the Model II in late 1978. It was announced in May 1979, deliveries began in October, and only Tandy-owned Radio Shack stores sold the computer. Tandy advertised the Model II as "a business computer — not a hobby, 'home' or personal computer". It claimed that the computer was "ideal for a small business, and also 'just right' for many time-consuming jobs within larger businesses", including those with mainframes or minicomputers. The base single disk version was , and a four disk version was . Hardware A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IBM 3740
IBM 3740 Data Entry System was a data entry system that was announced by IBM in 1973. It recorded data on an 8" diskette, a new recording medium from IBM, for fast, flexible, efficient data entry to either high-production, centralized operations or to decentralized, remote operations. The "Diskette" was more commonly known as an 8-inch floppy disk. History The system was announced in January, 1973; became available in the second quarter of that year; and was withdrawn from marketing in December, 1983.

80 Micro
''80 Micro'' was a computer magazine, published between 1980 and 1988, that featured program listings, products and reviews for the TRS-80. History Wayne Green, the creator of many magazines such as '' 73'', founded ''80 Microcomputing'' as a spinoff of his ''Kilobaud Microcomputing'' solely for Tandy Corporation's Radio Shack TRS-80 Model I microcomputer. Like his other magazines it encouraged readers to submit articles and reviews. A 1980 advertisement for the magazine promised that it would "tell you the truth … the good things about the TRS-80 and the not so good" because "Wayne Green has never been one to mince words". By 1982 ''80 Micro'' was the third largest magazine in terms of obtaining advertising, selling 152,000 issues; only ''Vogue'' and ''BYTE'' were larger. Renamed ''80 Micro'' on issue 30 in June/July 1982, the magazine's November 1982 issue had 518 pages, the most in its history for a regular issue. Green attributed the magazine's success to Radio Shack's po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VisiCalc
VisiCalc (for "visible calculator") is the first spreadsheet computer program for personal computers, originally released for Apple II by VisiCorp on 17 October 1979. It is often considered the application that turned the microcomputer from a hobby for computer enthusiasts into a serious business tool, prompting IBM to introduce the IBM PC two years later. VisiCalc is considered to be Apple II's killer app. It sold over 700,000 copies in six years, and as many as 1 million copies over its history. Initially developed for the Apple II computer using a 6502 assembler running on the Multics time sharing system, VisiCalc was ported to numerous platforms, both 8-bit and some of the early 16-bit systems. In order to do this, the company developed porting platforms that produced bug compatible versions. The company took the same approach when the IBM PC was launched, producing a product that was essentially identical to the original 8-bit Apple II version. Sales were initially brisk, ...

Scripsit
Scripsit is a word processing application written for the Radio Shack TRS-80 line of computers. Versions were available for most if not all computers sold under the TRS-80 name, including the Color Computer and several pocket computer designs, as well as the Tandy version of the Xenix operating system. Tandy Corp. also produced a version running under MS-DOS for its line of PC compatible computers (Tandy 1000 and successors). Some of the 8-bit versions are tape-based and have no ability to read or write to disk. The word scripsit is a Latin verb equivalent to the English "wrote". It was often used as an inscription indicating the identity of the person who wrote something. Functionality Scripsit is a rudimentary word processor. It has basic text entry and margin controls, as well as word wrap. Many versions tied to specific platforms were available, and each version had its own set of features. Most versions supported variable width fonts, specifically for daisy-wheel printer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BASIC
BASIC (Beginners' All-purpose Symbolic Instruction Code) is a family of general-purpose, high-level programming languages designed for ease of use. The original version was created by John G. Kemeny and Thomas E. Kurtz at Dartmouth College in 1963. They wanted to enable students in non-scientific fields to use computers. At the time, nearly all computers required writing custom software, which only scientists and mathematicians tended to learn. In addition to the program language, Kemeny and Kurtz developed the Dartmouth Time Sharing System (DTSS), which allowed multiple users to edit and run BASIC programs simultaneously on remote terminals. This general model became very popular on minicomputer systems like the PDP-11 and Data General Nova in the late 1960s and early 1970s. Hewlett-Packard produced an entire computer line for this method of operation, introducing the HP2000 series in the late 1960s and continuing sales into the 1980s. Many early video games trace their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobol
COBOL (; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural and, since 2002, object-oriented language. COBOL is primarily used in business, finance, and administrative systems for companies and governments. COBOL is still widely used in applications deployed on mainframe computers, such as large-scale batch and transaction processing jobs. However, due to its declining popularity and the retirement of experienced COBOL programmers, programs are being migrated to new platforms, rewritten in modern languages or replaced with software packages. Most programming in COBOL is now purely to maintain existing applications; however, many large financial institutions were still developing new systems in COBOL as late as 2006. COBOL was designed in 1959 by CODASYL and was partly based on the programming language FLOW-MATIC designed by Grace Hopper. It was created as part ...
