MultiPlan
Multiplan is spreadsheet program developed by Microsoft and introduced in 1982 as a competitor to VisiCalc. Multiplan was released first for computers running CP/M; it was developed using a Microsoft proprietary p-code machine, p-code C compiler as part of a Porting, portability strategy that facilitated ports to systems such as MS-DOS, Xenix, Commodore 64 and Commodore 128, 128, TI-99/4A (on four 6K GROMs and a single 8K ROM), TRS-80 Model II, Radio Shack TRS-80 Model II, TRS-80 Model 4, TRS-80 Model 100 (on ROM), Apple II series, Apple II, AT&T UNIX PC, and Burroughs B20 series. The CP/M version also ran on the TRS-80 Model II and 4, Commodore 128, and Apple II with a CP/M card. In France, Multiplan was also released for the Thomson computers in 1986 and same year on Japan for MSX compatible computers with name MSX-Plan. Despite the release of Microsoft Chart, a graphics companion program, Multiplan continued to be outsold by Lotus 1-2-3. Multiplan was replaced by Microsoft E ...

Spreadsheet
A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form. Spreadsheets were developed as computerized analogs of paper accounting worksheets. The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. The term ''spreadsheet'' may also refer to one such electronic document. Spreadsheet users can adjust any stored value and observe the effects on calculated values. This makes the spreadsheet useful for "what-if" analysis since many cases can be rapidly investigated without manual recalculation. Modern spreadsheet software can have multiple interacting sheets and can display data either as text and numerals or in graphical form. Besides performing basic arithmetic and mathematical functions, modern spreadsheets provide built-in functions for common financial a ...

Thomson Computers
In the 1980s the French Thomson company produced a range of 8-bit computers based on the 6809E CPU. They were released in several variations (mostly concerning the keyboard or color of the casing) covering the MO and TO series from late 1982 to 1989. While MO and TO models are incompatible in software, most of the peripherals and hardware were compatible. These machines were common in France due to the 1980s governmental educational program '' Computing for All (Informatique pour Tous)''.' Around 100,000 MO5 and TO7/70 computers were ordered and installed in schools. Export attempts to Germany, Italy, Algeria, USSR, India, Argentina and Spain were unsuccessful. It is reported that there were 450,000 Thomson computers in France in 1986. By 1988 Thomson had only sold 60,000 of the predicted 150,000 computers, abandoning computer development the following year. About 84 games were released for the TO7, 194 for the MO5, 3 for the TO7/70, 10 for the TO9, 21 for the MO6, and 128 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TRS-80 Model 100
The TRS-80 Model 100 is a portable computer introduced in April 26th, 1983. It is one of the first notebook-style computers, featuring a keyboard and liquid crystal display, in a battery-powered package roughly the size and shape of a notepad or large book. It was made by Kyocera, and originally sold in Japan as the Kyotronic 85. Although a slow seller for Kyocera, the rights to the machine were purchased by Tandy Corporation. The computer was sold through Radio Shack stores in the United States and Canada and affiliated dealers in other countries. It became one of the company's most popular models, with over 6 million units sold worldwide. The Olivetti M-10 and the NEC PC-8201 and PC-8300 were also built on the same Kyocera platform, with some design and hardware differences. It was originally marketed as a ''Micro Executive Work Station'' (MEWS), although the term did not catch on and was eventually dropped.

TRS-80 Model 4
The TRS-80 Model 4 is the last Z80-based home computer family by Radio Shack, sold from April 1983 through late 1991. Model 4 Tandy Corporation introduced the TRS-80 Model 4 in April 26th, 1983 as the successor to the TRS-80 Model III. The Model 4 has a faster Z80A 4 MHz CPU, larger video display of 80 columns by 24 rows, bigger keyboard, and can be upgraded to 128KB of RAM. It is compatible with Model III software and CP/M application software. The Model 4 was announced in the same April 1983 press release as was the TRS-80 Model 100 laptop. The two computers were often marketed by Tandy/Radio Shack as a complementary pair. A diskless Model 4 with 16KB RAM cost $999; with 64KB RAM and one single-sided 180K disk drive it cost $1699; with 64KB RAM and two drives it cost $1999.

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] |
Commodore 128
The Commodore 128, also known as the C128, C-128, C= 128,The "C=" represents the graphical part of the logo. is the last 8-bit home computer that was commercially released by Commodore Business Machines (CBM). Introduced in January 1985 at the CES in Las Vegas, it appeared three years after its predecessor, the bestselling computer in the 80s Commodore 64. The C128 is a significantly expanded successor to the C64, with nearly full compatibility. The newer machine has 128 KB of RAM in two 64 KB banks, and an 80-column color video output. It has a redesigned case and keyboard. Also included is a Zilog Z80 CPU which allows the C128 to run CP/M, as an alternative to the usual Commodore BASIC environment. The presence of the Z80 and the huge CP/M software library it brings, coupled with the C64's software library, gave the C128 one of the broadest ranges of available software among its competitors. The primary hardware designer of the C128 was Bil Herd, who had worked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porting
In software engineering, porting is the process of adapting software for the purpose of achieving some form of execution in a computing environment that is different from the one that a given program (meant for such execution) was originally designed for (e.g., different CPU, operating system, or third party library). The term is also used when software/hardware is changed to make them usable in different environments. Software is ''portable'' when the cost of porting it to a new platform is significantly less than the cost of writing it from scratch. The lower the cost of porting software relative to its implementation cost, the more portable it is said to be. Etymology The term "port" is derived from the Latin '' portāre'', meaning "to carry". When code is not compatible with a particular operating system or architecture, the code must be "carried" to the new system. The term is not generally applied to the process of adapting software to run with less memory on the sam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
