Disk Extended Color BASIC
Disk Extended Color Basic is an update to the Color BASIC interpreter for the Radio Shack/Tandy TRS-80 Color Computer series and is the default BASIC interpreter, and therefore the de facto operating system, for the Color Computer 3. The Color Computer Basic implementations are somewhat different for the versions of Basic which come with the other family of TRS-80 machines, namely Basic Levels I, II, and III. Assemblers Assembler may refer to: Arts and media * Nobukazu Takemura, avant-garde electronic musician, stage name Assembler * Assemblers, a fictional race in the ''Star Wars'' universe * Assemblers, an alternative name of the superhero group Champions of ... and Pascal and C compilers are available for the different machines in the series. Modified subsets of Color Basic may be found on many of the Radio Shack PC series of pocket computers (PC-1 to PC-4 by Sharp, PC-5, PC-6 to PC-8 by Casio) of the era. Color Basic was updated again for the Color Computer 3 and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Color Computer
The RadioShack TRS-80 Color Computer, later marketed as the Tandy Color Computer, is a series of home computers developed and sold by Tandy Corporation. Despite sharing a name with the earlier TRS-80, the Color Computer is a completely different system and a radical departure in design based on the Motorola 6809E processor rather than the Zilog Z80 of earlier models. The Tandy Color Computer line, nicknamed CoCo, started in 1980 with what is now called the Color Computer 1. It was followed by the Color Computer 2 in 1983, then the Color Computer 3 in 1986. All three models maintain a high level of software and hardware compatibility, with few programs written for an older model being unable to run on the newer ones. The Color Computer 3 was discontinued in 1991. All Color Computer models shipped with Color BASIC, an implementation of Microsoft BASIC, in ROM. Variants of the OS-9 multitasking operating system were available from third parties. History Tandy Corporation anno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color BASIC
Color BASIC is the implementation of Microsoft BASIC that is included in the ROM of the Tandy/Radio Shack TRS-80 Color Computers manufactured between 1980 and 1991. BASIC (Beginner's All-purpose Symbolic Instruction Code) is a high level language with simple syntax that makes it easy to write simple programs. Color BASIC is interpreted, that is, decoded as it is run. Background The nucleus of Color BASIC was Microsoft BASIC-69 which Tandy licensed from Microsoft. Color BASIC 1.0 was released with the original 4k TRS-80 Color Computer in 1980. It resides on 8k bytes of ROM, and is responsible for all 'housekeeping' duties on the system. This includes hardware initialization, memory management, interrupt processing, etc. Like most implementations of BASIC, each line of code starts with a line number and consists of one or more statements with variables and operators. 16k of memory is required for the next level of BASIC, Extended Color BASIC ("ECB"). Extended BASIC is required fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BASIC Interpreter
A BASIC interpreter is an Interpreter (computing), interpreter that enables users to enter and run programs in the BASIC programming language, language and was, for the first part of the microcomputer era, the default Application software, application that computers would launch. Users were expected to use the BASIC interpreter to type-in programs, type in programs or to load programs from storage (initially cassette tapes then floppy disks). BASIC interpreters are of historical importance. Microsoft's first product for sale was a BASIC interpreter (Altair BASIC), which paved the way for the company's success. Before Altair BASIC, microcomputers were sold as kits that needed to be programmed in machine code (for instance, the Apple I). During the Altair period, BASIC interpreters were sold separately, becoming the first software sold to individuals rather than to organizations; Apple BASIC was Apple's first software product. After the Altair 8800, MITS Altair 8800, microcomputers w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TRS-80
The TRS-80 Micro Computer System (TRS-80, later renamed the Model I to distinguish it from successors) is a desktop microcomputer developed by American company Tandy Corporation and sold through their Radio Shack stores. Launched in 1977, it is one of the earliest mass-produced and mass-marketed retail home computers. The name is an abbreviation of ''Tandy Radio Shack, Z80 [microprocessor]'', referring to its Zilog Z80 8-bit microprocessor. The TRS-80 has a full-stroke QWERTY keyboard, 4 kilobyte, KB dynamic random-access memory (DRAM) standard memory, small size and desk area, floating-point Level I BASIC language Interpreter (computing), interpreter in read-only memory (ROM), 64-character-per-line computer monitor, video monitor, and had a starting price of US$600 (equivalent to US$ in ). A cassette tape drive for program storage was included in the original package. While the software environment was stable, the cassette load/save process combined with keyboard bounce issues ...

Assembler (computing)
In computing, assembly language (alternatively assembler language or symbolic machine code), often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. Assembly language usually has one statement per machine instruction (1:1), but constants, comments, assembler directives, symbolic labels of, e.g., memory locations, registers, and macros are generally also supported. The first assembly code in which a language is used to represent machine code instructions is found in Kathleen and Andrew Donald Booth's 1947 work, ''Coding for A.R.C.''. Assembly code is converted into executable machine code by a utility program referred to as an '' assembler''. The term "assembler" is generally attributed to Wilkes, Wheeler and Gill in their 1951 book ''The Preparation of Programs for an Electronic Digi ...

Pascal (programming Language)
Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named after French mathematician, philosopher and physicist Blaise Pascal. Pascal was developed on the pattern of the ALGOL 60 language. Wirth was involved in the process to improve the language as part of the ALGOL X efforts and proposed a version named ALGOL W. This was not accepted, and the ALGOL X process bogged down. In 1968, Wirth decided to abandon the ALGOL X process and further improve ALGOL W, releasing this as Pascal in 1970. On top of ALGOL's scalars and arrays, Pascal enables defining complex datatypes and building dynamic and recursive data structures such as lists, trees and graphs. Pascal has strong typing on all objects, which means that one type of data cannot be converted to or interpreted as another without explicit conversions ...

C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

MC-10
The TRS-80 MC-10 microcomputer is a lesser-known member of the TRS-80 line of home computers, produced by Tandy Corporation in the early 1980s and sold through their RadioShack chain of electronics stores. It was a low-cost alternative to Tandy's own TRS-80 Color Computer to compete with entry-level machines such as the VIC-20 and Sinclair ZX81. The MC-10 was of value primarily to hobbyists and as an introduction to computer programming.It was not a commercial success and was discontinued only a year after its introduction. Description About the size of a hardcover book, the MC-10 has four kilobytes of RAM, a Motorola MC6803 eight-bit microprocessor, a built-in serial port, and graphics capabilities similar to those of the original Color Computer (provided by the same MC6847 video display generator). The MC-10 includes a BASIC interpreter in ROM and uses regular audio cassettes for bulk storage. Text and graphics are displayed on a television set via a built-in RF modulator. ...
