CBterm C64
CBterm/C64, commonly referred to as CBterm, is a terminal emulator for the Commodore 64, authored by Christopher "Chrisdos" Dunn. CBterm bears a copyright date of 1985; version 5.0 of the software was released in early 1987 and is coded entirely in assembly language. It features 40- and 80-column displays, XMODEM file transfers, ASCII/PETSCII conversion, direct display of RLE graphics, and support for a variety of autodialling modems. Support for the Punter protocol and VIDTEX and VT52 terminal emulation is possible by means of overlays. The software is freely redistributable for non-commercial use. CBterm 5.0 was favourably reviewed in ''Run'', with columnist Loren Lovhaug praising its speed, customizability, and CompuServe compatibility. Some criticism was levied at the lack of native support for Punter and for baud rates other than 300 and 1200.

Christopher Dunn (computer Enthusiast)
Christopher Dunn is a computer enthusiast noted for his involvement with CompuServe, and for the first high-profile online courtship leading to marriage in the United States. CompuServe contributions Around 1980, Dunn discovered CompuServe, an early online service popular with owners of 8-bit microcomputers. He served as the sysop of CBIG, a special interest group for users of CompuServe's CB Simulator chat service, where he went by the handle "Chrisdos". Dunn was the author of MU, an unofficial menu and mail notification program that ran on CompuServe's DEC PDP servers. (By 1984, it was no longer possible for customers to install and run server-side programs; MU was the sole exception.) In 1985, Dunn authored CBterm/C64, a terminal emulator for the Commodore 64 noted for its ability to directly display CompuServe's RLE graphics. Online dating In 1982, Dunn met Pamela Jensen through the CB Simulator. At the time, the 26-year-old Dunn lived in Queens, where he d ...

VIDTEX
VIDTEX is a family of telecommunication software developed for CompuServe for use with its online dial-up service. VIDTEX client software was available for Atari and Commodore 8-bit microcomputers, and was noted for its ability to directly display RLE graphics and its support for file transfers using the CompuServe B protocol Protocol may refer to: Sociology and politics * Protocol (politics), a formal agreement between nation states * Protocol (diplomacy), the etiquette of diplomacy and affairs of state * Etiquette, a code of personal behavior Science and technology .... Its popularity led to third-party VIDTEX terminal emulators, such as CBterm/C64, as well as stand-alone programs for displaying VIDTEX graphics. Large collections of VIDTEX graphics could also be found on independently operated BBSes. References {{software-stub Atari 8-bit family software Commodore 64 software CompuServe ...

Transactor Publishing
''The Transactor'' was a computer magazine directed at users of Commodore home computers. In contrast to other Commodore-focused publications such as '' Commodore Magazine'' and ''COMPUTE!'s Gazette'', ''The Transactor'''s popularity was based on its coverage of deep technical issues and hardware hacking. ''INFO'' called ''The Transactor'' "the undeniable authority" on "Commodore programming and hardware information". Publication history The magazine was launched on 30 April 1978 as the official international bulletin of Commodore Canada to PET user groups. The early issues were low-tech mimeographed productions with no non-Commodore advertising and a roughly monthly release schedule. Despite its association with Commodore, the magazine earned a reputation for being honest and upfront about bugs and faults in Commodore's products. In September 1982 the magazine was relaunched as a fully independent, bimonthly, advertiser-supported publication. From this point the magazine be ...

Baud Rate
In telecommunication and electronics, baud (; symbol: Bd) is a common unit of measurement of symbol rate, which is one of the components that determine the speed of communication over a data channel. It is the unit for symbol rate or modulation rate in symbols per second or pulses per second. It is the number of distinct symbol changes (signalling events) made to the transmission medium per second in a digitally modulated signal or a bd rate line code. Baud is related to ''gross bit rate'', which can be expressed in bits per second. If there are precisely two symbols in the system (typically 0 and 1), then baud and bit per second (bit/s) are equivalent. Naming The baud unit is named after Émile Baudot, the inventor of the Baudot code for telegraphy, and is represented according to the rules for SI units. That is, the first letter of its symbol is uppercase (Bd), but when the unit is spelled out, it should be written in lowercase (baud) except when it begins a sentence. It ...

CompuServe
CompuServe (CompuServe Information Service, also known by its initialism CIS) was an American online service provider, the first major commercial one in the world – described in 1994 as "the oldest of the Big Three information services (the others are Prodigy and America Online)." It dominated the field during the 1980s and remained a major influence through the mid-1990s. At its peak in the early 1990s, CIS was known for its online chat system, message forums covering a variety of topics, extensive software libraries for most computer platforms, and a series of popular online games, notably '' MegaWars III'' and '' Island of Kesmai''. It also was known for its introduction of the GIF format for pictures and as a GIF exchange mechanism. In 1997, 17 years after H&R Block had acquired CIS, the parent announced its desire to sell the company. A complex deal was worked out with WorldCom acting as a broker, resulting in CIS being sold to AOL. In 2015, Verizon acquired AOL, inclu ...

Freeware
Freeware is software, most often proprietary, that is distributed at no monetary cost to the end user. There is no agreed-upon set of rights, license, or EULA that defines ''freeware'' unambiguously; every publisher defines its own rules for the freeware it offers. For instance, modification, redistribution by third parties, and reverse engineering are permitted by some publishers but prohibited by others. Unlike with free and open-source software, which are also often distributed free of charge, the source code for freeware is typically not made available. Freeware may be intended to benefit its producer by, for example, encouraging sales of a more capable version, as in the freemium and shareware business models. History The term ''freeware'' was coined in 1982 by Andrew Fluegelman, who wanted to sell PC-Talk, the communications application he had created, outside of commercial distribution channels. Fluegelman distributed the program via a process now termed '' share ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overlay (programming)
In a general computing sense, overlaying means "the process of transferring a block of program code or other data into main memory, replacing what is already stored". Overlaying is a programming method that allows programs to be larger than the computer's main memory. An embedded system would normally use overlays because of the limitation of physical memory, which is internal memory for a system-on-chip, and the lack of virtual memory facilities. Usage Constructing an overlay program involves manually dividing a program into self-contained object code blocks called overlays or links, generally laid out in a tree structure. ''Sibling'' segments, those at the same depth level, share the same memory, called ''overlay region'' or ''destination region''. An overlay manager, either part of the operating system or part of the overlay program, loads the required overlay from external memory into its destination region when it is needed; this may be automatic or via explicit code.

VT52
The VT50 was a CRT-based computer terminal introduced by Digital Equipment Corporation (DEC) in July 1974. It provided a display with 12 rows and 80 columns of upper-case text, and used an expanded set of control characters and forward-only scrolling based on the earlier VT05. DEC documentation of the era refers to the terminals as the DECscope, a name that was otherwise almost never seen. The VT50 was sold only for a short period before it was replaced by the VT52 in September 1975. The VT52 provided a screen of 24 rows and 80 columns of text and supported all 95 ASCII characters as well as 32 graphics characters, bi-directional scrolling, and an expanded control character system. DEC produced a series of upgraded VT52's with additional hardware for various uses. The VT52 family was followed by the much more sophisticated VT100 in 1978. Description The VT50 supported asynchronous communication at baud rates up to 9600 bits per second and did not require any fill characters. ...
