PCI
 PCI SIG
   The PCI (Peripheral Component Interconnect) Local Bus is a high-performance bus that provides a processor-independent data path between the CPU and high-speed peripherals. PCI is a robust interconnect mechanism designed specifically to accommodate multiple high performance peripherals for graphics, full motion video, SCSI, LAN, etc.
PCMCIA
 Making Sense of PCMCIA (Dave Ruske)
  The acronym PCMCIA represents both the PC Card standard (which specifies both card hardware and system software requirements), and the organization responsible for developing it. Originally, the standard was designed exclusively for memory cards (Release 1.0). These cards were being used in small handheld and laptop systems in lieu of a floppy disk drive and were all 3.3 millimeters thick. These were Type I cards (the "Type" refers only to the physical thickness of a PC Card, nothing more). Later releases of the PCMCIA standard (Release 2.0 and up) were expanded to include I/O cards, such as modems or network cards. Manufacturers were hard-pressed to make these more demanding cards fit in the 3.3 mm Type I form factor, however, so a Type II card was introduced with a thickness of 5 mm. A Type III card was also defined; these are 10.5 mm in height, and are often used for tiny hard disk drives (now up to 450 MBytes on a 1.8" drive!). Some manufacturers have made still thicker cards for larger capacity drives; although this is often referred to as Type IV, this has not been officially adopted by PCMCIA. While the PCMCIA standard has grown significantly, it has done a pretty fair job of staying backward-compatible with earlier cards (a Type I card can be used in a Type II or III slot, for instance).
 PC Card Resource Directory (PCMCIA)
  PCMCIA (Personal Computer Memory Card International Association) is an international standards body and trade association with over 300 member companies that was founded in 1989 to establish standards for Integrated Circuit cards and to promote interchangeability among mobile computers where ruggedness, low power, and small size were critical.
 PC Card Technology Primer (PCMCIA)
  In the early 90's, the rapid growth of mobile computing drove the development of smaller, lighter, and more portable tools for information processing. One of the most exciting of these innovations was PC Card technology. The power and versatility of PC Cards quickly made them standard equipment in mobile computers.

SCSI

 SCSI Common Codes & Values (T10)
  The standardized collection of SCSI commands uses many specific codes and coded values to communicate requests and responses between the initiator and target. Informative summaries for several of the more commonly used codes and coded values are included as annex information in the SCSI Primary Commands - 2 (SPC-2) draft standard.
 SCSI Revision Levels (Seagate)
  SCSI (Small Computer System Interface) is an intelligent peripheral interface characterized by its use of high level communication between devices. Communications are defined as being between an "Initiator" and a "Target". The Initiator is normally a computer, and the Target is normally a peripheral. Data may be transferred in asynchronous (not clocked) or synchronous (clocked) mode. All messages and commands are always transferred in asynchronous mode.
 SCSI Supplier List (SCSI Trade Association)
  The SCSI Supplier List has been compiled by the STA as a partial list of SCSI Manufacturers
 SCSI: Frequently Asked Questions (FAQ)
 The T10 Technical Committee
  T10 is a Technical Committee of the National Committee on Information Technology Standards (NCITS, pronounced "insights"). It is responsible for Lower-Level Interfaces. Its principal work is the Small Computer System Interface (SCSI) [including SCSI-2 and a family of SCSI-3 projects].
