The JEIDA memory card standard is a popular memory card standard at the beginning of memory cards appearing on portable computers. JEIDA cards could be used to expand system memory [1] or as a solid-state storage drive.
Before the advent of the JEIDA standard, laptops had proprietary cards that were not interoperable with other manufacturers laptops, other laptop lines, or even other models in the same line. The establishment of the JEIDA interface and cards across Japanese portables provoked a response from the US government, through SEMATECH,[ citation needed ] and thus PCMCIA was born. PCMCIA and JEIDA worked to solve this rift between the two competing standards, and merged into JEIDA 4.0 or PCMCIA 1.0 in 1990.
The JEIDA memory card was used in earlier ThinkPad models, where IBM branded them as IC DRAM Cards. [2] [3]
Industry Standard Architecture (ISA) is the 16-bit internal bus of IBM PC/AT and similar computers based on the Intel 80286 and its immediate successors during the 1980s. The bus was (largely) backward compatible with the 8-bit bus of the 8088-based IBM PC, including the IBM PC/XT as well as IBM PC compatibles.
PC Card is a parallel peripheral interface for laptop computers and PDAs.
Static random-access memory is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory; data is lost when power is removed.
The Amiga 600, also known as the A600, is a home computer introduced in March 1992. It is the final Amiga model based on the Motorola 68000 and the 1990 Amiga Enhanced Chip Set. A redesign of the Amiga 500 Plus, it adds the option of an internal hard disk drive and a PCMCIA port. Lacking a numeric keypad, the A600 is only slightly larger than an IBM PC keyboard, weighing approximately 6 pounds (2.72kg). It shipped with AmigaOS 2.0, which was considered more user-friendly than earlier versions of the operating system.
The Personal Computer Memory Card International Association (PCMCIA) was a group of computer hardware manufacturers, operating under that name from 1989 to 2009. Starting with the PCMCIA card in 1990, it created various standards for peripheral interfaces designed for laptop computers.
In computing, an expansion card is a printed circuit board that can be inserted into an electrical connector, or expansion slot on a computer's motherboard to add functionality to a computer system. Sometimes the design of the computer's case and motherboard involves placing most of these slots onto a separate, removable card. Typically such cards are referred to as a riser card in part because they project upward from the board and allow expansion cards to be placed above and parallel to the motherboard.
A DIMM, or Dual In-Line Memory Module, is a type of computer memory module used in desktop, laptop, and server computers. It is a circuit board that contains memory chips and connects to the computer's motherboard. A DIMM is often called a "RAM stick" due to its shape and size. A DIMM comprises a series of dynamic random-access memory integrated circuits that are mounted to its circuit board. DIMMs are the predominant method for adding memory into a computer system. The vast majority of DIMMs are standardized through JEDEC standards, although there are proprietary DIMMs. DIMMs come in a variety of speeds and sizes, but generally are one of two lengths - PC which are 133.35 mm (5.25 in) and laptop (SO-DIMM) which are about half the size at 67.60 mm (2.66 in).
A memory card is an electronic data storage device used for storing digital information, typically using flash memory. These are commonly used in digital portable electronic devices. They allow adding memory to such devices using a card in a socket instead of protruding USB flash drives.
CompactFlash (CF) is a flash memory mass storage device used mainly in portable electronic devices. The format was specified and the devices were first manufactured by SanDisk in 1994.
Super VGA (SVGA) is a broad term that covers a wide range of computer display standards that extended IBM's VGA specification.
ExpressCard, initially called NEWCARD, is an interface to connect peripheral devices to a computer, usually a laptop computer. The ExpressCard technical standard specifies the design of slots built into the computer and of expansion cards to insert in the slots. The cards contain electronic circuits and sometimes connectors for external devices. The ExpressCard standard replaces the PC Card standards.
The MPU-401, where MPU stands for MIDI Processing Unit, is an important but now obsolete interface for connecting MIDI-equipped electronic music hardware to personal computers. It was designed by Roland Corporation, which also co-authored the MIDI standard.
Thin small outline package (TSOP) is a type of surface mount IC package. They are very low-profile and have tight lead spacing.
In computing, a memory module or RAM stick is a printed circuit board on which memory integrated circuits are mounted. Memory modules permit easy installation and replacement in electronic systems, especially computers such as personal computers, workstations, and servers. The first memory modules were proprietary designs that were specific to a model of computer from a specific manufacturer. Later, memory modules were standardized by organizations such as JEDEC and could be used in any system designed to use them.
The UltraLite was an IBM PC-compatible laptop released by NEC in October 1988. It was released alongside the heavier and more-capable ProSpeed. The UltraLite was based on the NEC V30 microprocessor; the computer includes MS-DOS 3.3 built into ROM.
The Amiga 1200, or A1200, is a personal computer in the Amiga computer family released by Commodore International, aimed at the home computer market. It was launched on October 21, 1992, at a base price of £399 in the United Kingdom and $599 in the United States.
The IBM Thinkpad 350 series was a notebook computer series introduced in 1993 by IBM as part of their Thinkpad laptop series. It was the successor to the IBM ThinkPad 300. With only 2 models ever made in the series, it was succeeded in 1994 by the IBM Thinkpad 360 series.
The Personal System/2 Model 30 and Personal System/2 Model 30 286 are IBM's entry-level desktop computers in their Personal System/2 (PS/2) family of personal computers. As opposed to higher-end entries in the PS/2 line which use Micro Channel bus architecture, the Model 30 features an Industry Standard Architecture bus, allowing it to use expansion cards from its direct predecessors, the PC/XT and the PC/AT. The original PS/2 Model 30 is built upon the Intel 8086 microprocessor clocked at 8 MHz; the Model 30 286 features the Intel 80286 clocked at 10 MHz.
Cumulus Corporation was an American computer peripheral and system manufacturer active from 1987 to 1993. Based in Beachwood, Ohio and started by Tecmar founder Martin Alpert, the company set out to exclusively manufacture expansion products for IBM's Personal System/2 (PS/2) family of computers—mainly RAM expansion cards. It later released cross-platform CPU upgrade cards and memory expansion cards for other platforms besides the PS/2. Beginning in 1990, the company began trading as Cumulus Computer Corporation and began releasing complete systems of their own. Initially a success story for the tech industry in Cleveland, a botched stock launch in 1992 proved disastrous for the company's ailing cash flow situation, and in 1993 the company was liquidated amid massive debt to suppliers and lenders.
New Media Corporation, also known as New Media Technology Corporation, was an American computer company active from 1992 to the early 2000s. The company focused on the design and manufacture of PC Cards, a type of expansion card bus for laptops that had their heyday from the early 1990s to the mid-2000s. New Media was privately held and based out of Irvine, California.
