SpeedScript
SpeedScript is a word processor originally printed as a type-in MLX machine language listing in 1984-85 issues of ''Compute!'' and ''Compute!'s Gazette'' magazines. Approximately 5 KB in length, it provided many of the same features as commercial word processing packages of the 8-bit era, such as PaperClip and Bank Street Writer. Versions were published for the Apple II, Commodore 64 and 128, Atari 8-bit family, VIC-20, and MS-DOS. Versions In April 1983 ''Compute!'' published Scriptor, a word processor written by staff writer Charles Brannon in BASIC and assembly language, as a type-in program for the Atari 8-bit family. In January 1984 version 1.0 of his new word processor SpeedScript appeared in ''Compute!'s Gazette'' for the Commodore 64 and VIC-20. 1.1 appeared in ''Compute!'s Second Book of Commodore 64'', 2.0 on ''Gazette Disk'' in May 1984, and 3.0 in ''Compute!'' in March and April 1985.

MOS Technology VDC
The 8563 Video Display Controller (VDC) was an integrated circuit produced by MOS Technology. It was used in the Commodore 128 (C128) computer to generate an 80-column (640×200 pixel) RGB video display, running alongside a VIC-II which supported Commodore 64-compatible graphics. The DCR models (as well as a few D-models) of the C128 used the later and more technically advanced 8568 DC controller. History and characteristics Originally intended for a planned (but unreleased) UNIX-based business computer based around the Zilog Z8000, Commodore designed the VDC into several prototype machines. Of these, only the Commodore 128 ever saw production. Unlike earlier MOS video chips such as the popular VIC-II, the VDC had dedicated video memory, 16 kilobytes (16,384 bytes; upgradable to 64 kilobytes, 65,536 bytes) in the original or "flat" C128 and 64 kilobytes in the C128DCR. This RAM was not directly accessible by the microprocessor. The 8563 was more difficult to produce than most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type-in Program
A type-in program or type-in listing was computer source code printed in a home computer magazine or book. It was meant to be entered via the keyboard by the reader and then saved to cassette tape or floppy disk. The result was a usable game, utility, or application program. Type-in programs were common in the home computer era from the late 1970s through the early 1990s, when the RAM of 8-bit systems was measured in kilobytes and most computer owners did not have access to networks such as bulletin board systems. Magazines such as ''Softalk'', ''Compute!'', '' ANALOG Computing'', and ''Ahoy!'' dedicated much of each issue to type-in programs. The magazines could contain multiple games or other programs for a fraction of the cost of purchasing commercial software on removable media, but the user had to spend up to several hours typing each one in. Most listings were either in a system-specific BASIC dialect or machine code. Machine code programs were long lists of decimal o ...

MLX (software)
MLX is a series of machine language entry utilities published by the magazines ''COMPUTE!'' and ''COMPUTE!'s Gazette'', as well as books from COMPUTE! Publications. These programs were designed to allow relatively easy entry of the type-in machine language listings that were often included in these publications. Versions were available for the Commodore 64, VIC-20, Atari 8-bit family, and Apple II. MLX listings were reserved for relatively long machine language programs such as SpeedScript, some high-performance utilities, and fast-paced games. First version MLX was introduced in the December 1983 issue of ''COMPUTE!'' for the Commodore 64 and Atari 8-bit family (necessary to input the Atari gamChopperoidson Pg 122), and simultaneously in the December 1983 issue of ''COMPUTE!'s Gazette'' to be used for the entry of two C-64 machine language games, the excellenSpike(Pg 74) and the competitivSpace Duel(Pg 80). This was followed by a version in the January 1984 issue of ''COMPU ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compute!
''Compute!'' (), often stylized as ''COMPUTE!'', was an American home computer magazine that was published from 1979 to 1994. Its origins can be traced to 1978 in Len Lindsay's ''PET Gazette'', one of the first magazines for the Commodore PET computer. In its 1980s heyday ''Compute!'' covered all major platforms, and several single-platform spinoffs of the magazine were launched. The most successful of these was ''Compute!'s Gazette'', which catered to VIC-20 and Commodore 64 computer users. History ''Compute!''s original goal was to write about and publish programs for all of the computers that used some version of the MOS Technology 6502 CPU. It started out in 1979 with the Commodore PET, VIC-20, Atari 400/800, Apple II+, and some 6502-based computers one could build from kits, such as the Rockwell AIM 65, the KIM-1 by MOS Technology, and others from companies such as Ohio Scientific. Coverage of the kit computers and the Commodore PET were eventually dropped. The platforms t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compute!'s Gazette
''Compute!'s Gazette'' (), stylized as ''COMPUTE!'s Gazette'', was a computer magazine of the 1980s, directed at users of Commodore's 8-bit home computers. Announced as ''The Commodore Gazette'', it was a Commodore-only daughter magazine of the computer hobbyist magazine ''Compute!''. It was first published in July 1983. It contained both standard articles and type-in programs. Many of these programs were quite long and sophisticated. To assist in entry, ''Gazette'' published several utilities. The Automatic Proofreader provided checksum capabilities for BASIC programs, while machine language listings could be entered with MLX. Starting in May 1984, a companion disk with each issue's programs was available to subscribers for an extra fee. Perhaps its most popular and enduring type-in application was the ''SpeedScript'' word processor. A monthly column, "The VIC Magician" by Michael Tomczyk, presented BASIC programming tips and tricks for the VIC-20 and Commodore 64. The publ ...

Assembly Language
In computer programming, assembly language (or 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 Digital Com ...

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] |
Kermit (protocol)
Kermit is a computer file transfer/management protocol and a set of communications software tools primarily used in the early years of personal computing in the 1980s. It provides a consistent approach to file transfer, terminal emulation, script programming, and character set conversion across many different computer hardware and operating system platforms. Technical The Kermit protocol supports text and binary file transfers on both full-duplex and half-duplex 8-bit and 7-bit serial connections in a system- and medium-independent fashion, and is implemented on hundreds of different computer and operating system platforms. On full-duplex connections, a sliding window protocol is used with selective retransmission which provides excellent performance and error recovery characteristics. On 7-bit connections, locking shifts provide efficient transfer of 8-bit data. When properly implemented, as in the Columbia University Kermit Software collection, its authors claim performance i ...
