Toshiba T1000
The Toshiba T1000 was a laptop computer manufactured by the Toshiba Corporation in 1987. It had a similar specification to the IBM PC Convertible, with a 4.77 MHz 80C88 processor, 512 KB of RAM, and a monochrome CGA-compatible LCD. Unlike the Convertible, it includes a standard serial port and parallel port, connectors for an external monitor, and a real-time clock. Unusually for an IBM compatible PC, the T1000 contained a 256 KB ROM with a copy of MS-DOS 2.11. This acted as a small, read-only hard drive. Alternative operating systems could still be loaded from the floppy drive, or (if present) the RAM disk. Along with the T1200 and earlier T1100, the Toshiba T1000 was one of the early computers to feature a "laptop" form factor and battery-powered operation. Reception ''PC Magazine'' in 1988 named the Toshiba T1000 an "Editor's Choice" among 12 tested portable computers. One reviewer called it "the first real DOS laptop" and a plausible replacement for his Tandy 200, whil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toshiba T1000LE
The Toshiba T1000LE was a Toshiba laptop made in 1990 as a member of their LE/SE/XE family. It used a 9.54/4.77 MHz Intel 80C86, with the clock speed being switchable by using function keys on the keyboard. The laptop came with a 20 MB hard drive, 1 MB of RAM, a 1.44M/720K switchable 3.5" floppy drive, and a blue-on-white, back-lit, "Toshiba Graphics" 640x400 STN LCD. The laptop came with a choice of either MS-DOS 3.3 or 4.01 stored in a socketed ROM. The laptop's RAM was expandable to 2 MB, 3 MB, 5 MB, or 9 MB with 1 MB, 2 MB, 4 MB, and 8 MB proprietary memory cards, respectively. The Toshiba T1000LE was discontinued prior to 1994. Specifications Features The Toshiba T1000LE was one of the first laptops to include both a hard drive and a Ni-CD battery. Previous laptops did not have enough power to run a hard drive from battery power (exceptions include the Toshiba T1200, which had a proprietary 26-pin JVC hard drive, and the Macintosh Portable, which used a lead-acid ba ...

Toshiba T3100
The Toshiba T3100 was a portable PC manufactured by Toshiba released in 1986. It featured a hard drive, 8 MHz Intel 80286 CPU and a black & orange 9.6" gas-plasma display with a resolution of 640x400 pixels. The portable had for the time a special high-resolution 640 x 400 display mode which is similar to and partially compatible with the Olivetti/AT&T 6300 graphics. The base model had 640 KB memory. There is a single proprietary expansion slot for 1200 bit/s modem, expansion chassis for 5x 8-bit ISA cards, Ethernet NIC, 2400 bit/s modem, and a 2 MB memory card (thus 2.6 MB in max total). T3100e model had 1 MB of memory, which could be upgraded to 5 MB. Toshiba T3100 was not a true portable, because it needed an external power source in all except the last version. Five versions existed: *The T3100/20 is essentially the same as the base T3100 but with a larger hard drive (20 MB instead of 10 MB). *The T3100e has a 12 MHz 80286 CPU (switchable to 6 MHz, 1 MB R ...

IBM Personal Computer XT
The IBM Personal Computer XT (model 5160, often shortened to PC/XT) is the second computer in the IBM Personal Computer line, released on March 8, 1983. Except for the addition of a built-in hard drive and extra expansion slots, it is very similar to the original IBM PC model 5150 from 1981. Name IBM did not specify an expanded form of "XT" on the machine, press releases, brochures or documentation, but some publications expanded the term as "''eXtended Technology''" or just "''eXTended''". Features The XT was regarded as an incremental improvement over the PC and a disappointment compared to the next-generation successor that some had anticipated. Compared to the original IBM PC, the XT has the following major differences: * The number of expansion slots is increased from five to eight * Base RAM is increased to at least 128 KB * 2x32KB ROM ICs replace the previous 6x8KB ROM ICs * A 10 MB hard drive is included as standard equipment * PC DOS 2.0 is included * The ...

Nickel–cadmium Battery
The nickel–cadmium battery (Ni–Cd battery or NiCad battery) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. The abbreviation ''Ni-Cd'' is derived from the chemical symbols of nickel (Ni) and cadmium (Cd): the abbreviation ''NiCad'' is a registered trademark of SAFT Corporation, although this brand name is commonly used to describe all Ni–Cd batteries. Wet-cell nickel-cadmium batteries were invented in 1899. A Ni-Cd battery has a terminal voltage during discharge of around 1.2 volts which decreases little until nearly the end of discharge. The maximum electromotive force offered by a Ni-Cd cell is 1.3V. Ni-Cd batteries are made in a wide range of sizes and capacities, from portable sealed types interchangeable with carbon-zinc dry cells, to large ventilated cells used for standby power and motive power. Compared with other types of rechargeable cells they offer good cycle life and performance at low temperatures with a fai ...

NEC PC-8201
The TRS-80 Model 100 is a portable computer introduced in April 26th, 1983. It is one of the first notebook-style computers, featuring a keyboard and liquid crystal display, in a battery-powered package roughly the size and shape of a notepad or large book. It was made by Kyocera, and originally sold in Japan as the Kyotronic 85. Although a slow seller for Kyocera, the rights to the machine were purchased by Tandy Corporation. The computer was sold through Radio Shack stores in the United States and Canada and affiliated dealers in other countries. It became one of the company's most popular models, with over 6 million units sold worldwide. The Olivetti M-10 and the NEC PC-8201 and PC-8300 were also built on the same Kyocera platform, with some design and hardware differences. It was originally marketed as a ''Micro Executive Work Station'' (MEWS), although the term did not catch on and was eventually dropped. Specifications * Processor: 8-bit Oki 80C85, CMOS, * Memory ...

BYTE
The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as The Internet Protocol () refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The first bit is number 0, making the eighth bit number 7. The size of the byte has historically been hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six-bit character code was an often-used implementation in early encoding systems, and computers using six-bit and nine-bit bytes were common in the 1960s. These systems often had memory words ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
