ISEPIC
The ISEPIC from Starpoint Software in USA is an extension cartridge which was introduced in June 1985 for the Commodore 64. It offers the capability to memory dump software regardless of the implementation scheme or storage medium. The resulting snapshot can be tested before saving. Snapshots require ISEPIC to run. The cartridge vanished at the end of 1985 but still sold 20,000 units around the world, mostly by word of mouth at local computer clubs and niche magazines. A major factor is the 2 kB RAM that could be reprogrammed And thus allowed the user to change its functionality. The 2 kB RAM is memory banked into a 256-byte page at 0xDF00 – 0xDFFF. Reception '' Ahoy!'' in October 1985 stated that "the ramifications of SEPIC The single-ended primary-inductor converter (SEPIC) is a type of DC/DC converter that allows the electrical potential (voltage) at its output to be greater than, less than, or equal to that at its input. The output of the SEPIC is controlled by t .. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crack Intro
__NOTOC__ A crack intro, also known as a cracktro, loader, or just intro, is a small introduction sequence added to cracked software. It aims to inform the user which "cracking crew" or individual cracker removed the software's copy protection and distributed the crack. They first appeared on Apple II computer in the late 1970s or early 1980s, and then on ZX Spectrum, Commodore 64 and Amstrad CPC games that were distributed around the world via Bulletin Board Systems (BBSes) and floppy disk copying. By 1985, when reviewing the commercially available ISEPIC cartridge which adds a custom crack intro to memory dumps of Commodore 64 software, '' Ahoy!'' wrote that such intros were "in the tradition of the true hacker". Early crack intros resemble graffiti in many ways, although they invaded the private sphere and not the public space. As time went on, crack intros became a medium to demonstrate the purported superiority of a cracking group. Such intros grew very complex, sometimes ex ...

Trilogic Expert Cartridge
The Expert Cartridge from the UK company Trilogic was a popular extension cartridge which was introduced in mid-1986 for the Commodore 64 and a later Commodore 128 compatible version, It offered a ''fast loader'', increasing the speeds of the disk drive, and a ''freezer'', allowing the program execution to be stopped to be resumed later. Later Cat & Korsh International took over the distribution and the Trilogic name disappeared from the cartridge. A major difference to the other two The Final Cartridge III and Action Replay is that it held its system software in an 8 kB RAM that could be reprogrammed. And thus allowed the user to change its functionality. The author of the Expert Cartridge default firmware is John Twiddy who also programmed ''The Last Ninja'' for the Commodore 64. He claims that it saved him many months of programming.Your Commodore Issue 48, September 1988 See also * ISEPIC - An earlier cartridge with 2 kB RAM * The Final Cartridge III The Final Cartridge I ...

ROM Cartridge
A ROM cartridge, usually referred to in context simply as a cartridge, cart, or card, is a replaceable part designed to be connected to a consumer electronics device such as a home computer, video game console or, to a lesser extent, electronic musical instruments. ROM cartridges allow users to rapidly load and access programs and data alongside a floppy drive in a home computer; in a video game console, the cartridges are standalone. At the time around their release, ROM cartridges provided security against unauthorised copying of software. However, the manufacturing of ROM cartridges was more expensive than floppy disks, and the storage capacity was smaller. ROM cartridges and slots were also used for various hardware accessories and enhancements. The widespread usage of the ROM cartridge in video gaming applications has led it to be often colloquially called a game cartridge. History ROM cartridges were popularized by early home computers which featured a special b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commodore 64
The Commodore 64, also known as the C64, is an 8-bit home computer introduced in January 1982 by Commodore International (first shown at the Consumer Electronics Show, January 7–10, 1982, in Las Vegas). It has been listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 12.5 and 17 million units. Volume production started in early 1982, marketing in August for . Preceded by the VIC-20 and Commodore PET, the C64 took its name from its of RAM. With support for multicolor sprites and a custom chip for waveform generation, the C64 could create superior visuals and audio compared to systems without such custom hardware. The C64 dominated the low-end computer market (except in the UK and Japan, lasting only about six months in Japan) for most of the later years of the 1980s. For a substantial period (1983–1986), the C64 had between 30% and 40% share of the US market and two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Memory Dump
In computing, a core dump, memory dump, crash dump, storage dump, system dump, or ABEND dump consists of the recorded state of the working memory of a computer program at a specific time, generally when the program has crashed or otherwise terminated abnormally. In practice, other key pieces of program state are usually dumped at the same time, including the processor registers, which may include the program counter and stack pointer, memory management information, and other processor and operating system flags and information. A snapshot dump (or snap dump) is a memory dump requested by the computer operator or by the running program, after which the program is able to continue. Core dumps are often used to assist in diagnosing and debugging errors in computer programs. On many operating systems, a fatal exception in a program automatically triggers a core dump. By extension, the phrase "to dump core" has come to mean in many cases, any fatal error, regardless of whether a recor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ahoy!
''Ahoy!'' was a computer magazine published between January 1984 and January 1989 in the US, focusing on all Commodore color computers, but especially the Commodore 64 and Amiga. History The first issue of ''Ahoy!'' was published in January 1984. The magazine was published monthly by Ion International and was headquartered in New York City. It published many games in BASIC and machine language, occasionally also printing assembly language source code. ''Ahoy!'' published a checksum A checksum is a small-sized block of data derived from another block of digital data for the purpose of detecting errors that may have been introduced during its transmission or storage.

Home Computer Peripherals
A home, or domicile, is a space used as a permanent or semi-permanent residence for one or many humans, and sometimes various companion animals. It is a fully or semi sheltered space and can have both interior and exterior aspects to it. Homes provide sheltered spaces, for instance rooms, where domestic activity can be performed such as sleeping, preparing food, eating and hygiene as well as providing spaces for work and leisure such as remote working, studying and playing. Physical forms of homes can be static such as a house or an apartment, mobile such as a houseboat, trailer or yurt or digital such as virtual space. The aspect of ‘home’ can be considered across scales; from the micro scale showcasing the most intimate spaces of the individual dwelling and direct surrounding area to the macro scale of the geographic area such as town, village, city, country or planet. The concept of ‘home’ has been researched and theorized across disciplines – topics rangin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
