ST BOOK
The ST BOOK is a subnotebook released in 1991 by Atari Corporation. It is based on the Atari STE. The ST BOOK is more portable than the previous Atari portable, the Atari STacy, STacy, but it sacrifices several features in order to achieve this: notably the backlight, and internal floppy disc drive. The screen is highly reflective. It supports the 640×400 1-bit mono mode only without an external video port. It gained some popularity as being the most utterly portable full-featured computer of the day (slim, light, quiet, reliable, and with a long battery life, even by modern standards for all 5). The ST BOOK is shipped with a modified version of TOS 2.06. Specifications Model number: NST-141 * Blitter * Character set: Atari ST character set (based on codepage 437) * Real-time clock Lithium Battery * Parallel: Yes (1 port) * Serial: Yes (1 port) * ACSI/FDD: Yes (1 port) * Midi: Yes (2 ports) * External keyboard * Internal Modem: optional (used for this model's expansion port) ...

Atari Corporation
Atari Corporation was an American manufacturer of computers and video game consoles. It was founded by Jack Tramiel on May 17, 1984, as Tramel Technology, Ltd., but then took on the Atari name less than two months later when WarnerMedia, Warner Communications sold the home computing and game console assets of Atari, Inc. to Tramiel. Its chief products were the Atari ST, Atari 8-bit family#XE series, Atari XE, Atari 7800, Atari Lynx and Atari Jaguar. The company Reverse takeover, reverse merged with JT Storage, JTS Inc. in 1996, becoming a small division which itself closed after JTS sold all Atari assets to Hasbro Interactive in 1998. History The company was founded by Commodore International's founder Jack Tramiel soon after his resignation from Commodore in January 1984. Initially named Tramel Technology, Ltd., the company's goal was to design and sell a next-generation home computer. On July 1, 1984, TTL bought the Consumer Division assets of Atari, Inc. from Warner, and T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atari STacy
The STacy is a portable computer version of the Atari ST. The computer was originally designed to operate on 12 standard C cell flashlight batteries for portability. When Atari realized how quickly the machine would use up a set of batteries (especially when rechargeable batteries of the time supplied insufficient power compared to the intended alkalines), they simply glued the lid of the battery compartment shut. The STacy has features similar to the Macintosh Portable, a version of Apple's Macintosh computer which contained a built in keyboard and monitor. With built-in MIDI, the STacy enjoyed success for running music-sequencer software and as a controller of musical instruments among both amateurs and well-known musicians.Time Capsule: The Atari Report - Spring 1990 by Sam Tramiel, Date: ...

Real-time Clock
A real-time clock (RTC) is an electronic device (most often in the form of an integrated circuit) that measures the passage of time. Although the term often refers to the devices in personal computers, servers and embedded systems, RTCs are present in almost any electronic device which needs to keep accurate time of day. Terminology The term ''real-time clock'' is used to avoid confusion with ordinary hardware clocks which are only signals that govern digital electronics, and do not count time in human units. RTC should not be confused with real-time computing, which shares its three-letter acronym but does not directly relate to time of day. Purpose Although keeping time can be done without an RTC, using one has benefits: * Low power consumption (important when running from alternate power) * Frees the main system for time-critical tasks * Sometimes more accurate than other methods A GPS receiver can shorten its startup time by comparing the current time, according to its ...

Codepage 437
Code page 437 (CCSID 437) is the character set of the original IBM PC (personal computer). It is also known as CP437, OEM-US, OEM 437, PC-8, or DOS Latin US. The set includes all printable ASCII characters as well as some accented letters (diacritics), Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "OEM font" or "high ASCII", or as " extended ASCII" (one of many mutually incompatible ASCII extensions). This character set remains the primary set in the core of any EGA and VGA-compatible graphics card. As such, text shown when a PC reboots, before fonts can be loaded and rendered, is typically rendered using this character set. Many file formats developed at the time of the IBM PC are based on code page 437 as well. Display adapters The original IBM PC contained this font as a 9×14 pixels-per-character font stored in the ROM of the IBM Monochrome Display Adapter (MDA) and an 8×8 pixels-per-character font of the Color Graphics Adapter ( CGA) ...

Atari ST Character Set
The Atari ST character set is the character set of the Atari ST personal computer family including the Atari STE, TT and Falcon. It is based on code page 437, the original character set of the IBM PC, and like that set includes ASCII codes 32–126, extended codes for accented letters (diacritics), and other symbols. It differs from code page 437 in using other dingbats at code points 0–31, in exchanging the box-drawing characters 176–223 for the Hebrew alphabet and other symbols, and exchanging code points 158, 236 and 254–255 with the symbols for sharp S, line integral, cubed and macron. The Atari ST family of computers contained this font stored in ROM in three sizes; as an 8×16 pixels-per-character font used in the high-resolution graphics modes, as an 8×8 pixels-per-character font used in the low- and medium-resolution graphics modes, and as a 6×6 pixels-per-character font used for icon labels in any graphics mode. All 256 codes were assigned a graphical chara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blitter
A blitter is a circuit, sometimes as a coprocessor or a logic block on a microprocessor, dedicated to the rapid movement and modification of data within a computer's memory. A blitter can copy large quantities of data from one memory area to another relatively quickly, and in parallel with the CPU, while freeing up the CPU's more complex capabilities for other operations. A typical use for a blitter is the movement of a bitmap, such as windows and fonts in a graphical user interface or images and backgrounds in a 2D video game. The name comes from the bit blit operation of the 1973 Xerox Alto, which stands for bit-block transfer. A blit operation is more than a memory copy, because it can involve data that's not byte aligned (hence the ''bit'' in ''bit blit''), handling transparent pixels (pixels which should not overwrite the destination), and various ways of combining the source and destination data. Blitters have largely been superseded by programmable graphics processing uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subnotebook
Subnotebook, also called ultraportable, superportable, or mini notebook, was a marketing term for laptop computers that are smaller and lighter than a typical notebook-sized laptop. Types and sizes As typical laptop sizes have decreased over the course of the 2010s, and other distinguishing features have become mainstream, the distinction between regular-size and 'subnotebook' laptops has largely disappeared. To the extent that it still exists, 'subnotebook' could be defined as machines with screen smaller than 13" but with a permanently-attached keyboard intended for two-handed typing. Prior to this convergence, subnotebooks were also distinguished from netbooks and ultra-mobile PCs, based on both size and market position. Classic subnotebooks were smaller than full sized laptops but larger than handheld computers. They were distinguished by smaller screens and bodies and lighter weights relative to contemporaneous laptops. The savings in size and weight were often achieved p ...

Passive Matrix Addressing
Passive matrix addressing is an addressing scheme used in early LCDs. This is a matrix addressing scheme meaning that only ''m'' + ''n'' control signals are required to address an ''m'' × ''n'' display. A pixel in a passive matrix must maintain its state without active driving circuitry until it can be refreshed again. The signal is divided into a row or ''select signal'' and a column or ''video signal''. The select voltage determines the row that is being addressed and all ''n'' pixels on a row are addressed simultaneously. When pixels on a row are being addressed, a ''Vsel'' potential is applied, and all other rows are unselected with a ''Vunsel'' potential. The video signal or column potential is then applied with a potential for each ''m'' columns individually. An on-switched (lit) pixel corresponds to a ''Von'', an off-switched (unlit) corresponds to a ''Voff'' potential. The potential across pixel at selected row ''i'' and column ''j'' is :V_ = V_ ...

Atari TOS
TOS (The Operating System) is the operating system of the Atari ST range of computers. This range includes the 520ST and 1040ST, their STF/M/FM and STE variants and the Mega ST/STE. Later, 32-bit machines ( TT, Falcon030) were developed using a new version of ''TOS'', called MultiTOS, which allowed multitasking. More recently, users have further developed TOS into FreeMiNT. Details Atari TOS (The Operating System) debuted with the Atari 520ST in 1985. TOS combines Digital Research's GEM GUI running on top of the DOS-like GEMDOS. Features include a flat memory model, DOS-compatible disk format (starting with TOS 1.04), support for MIDI, and a variant of SCSI called ACSI in later versions. Atari's TOS is usually run from ROM chips contained in the computer: Thus, before local hard drives were available in home computers, it was an almost instant-running OS. TOS booted off floppy disks in the very first STs, but only about half a year after the ST was introduced, all ST models s ...

Floppy Disk
A floppy disk or floppy diskette (casually referred to as a floppy, or a diskette) is an obsolescent type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk. Floppy disks store digital data which can be read and written when the disk is inserted into a floppy disk drive (FDD) connected to or inside a computer or other device. The first floppy disks, invented and made by IBM, had a disk diameter of . Subsequently, the 5¼-inch and then the 3½-inch became a ubiquitous form of data storage and transfer into the first years of the 21st century. 3½-inch floppy disks can still be used with an external USB floppy disk drive. USB drives for 5¼-inch, 8-inch, and other-size floppy disks are rare to non-existent. Some individuals and organizations continue to use older equipment to read or transfer data from floppy disks.

Megabyte
The megabyte is a multiple of the unit byte for digital information. Its recommended unit symbol is MB. The unit prefix ''mega'' is a multiplier of (106) in the International System of Units (SI). Therefore, one megabyte is one million bytes of information. This definition has been incorporated into the International System of Quantities. In the computer and information technology fields, other definitions have been used that arose for historical reasons of convenience. A common usage has been to designate one megabyte as (220 B), a quantity that conveniently expresses the binary architecture of digital computer memory. The standards bodies have deprecated this usage of the megabyte in favor of a new set of binary prefixes, in which this quantity is designated by the unit mebibyte (MiB). Definitions The unit megabyte is commonly used for 10002 (one million) bytes or 10242 bytes. The interpretation of using base 1024 originated as technical jargon for the byte SI prefix, mult ...
