A focus of the STD bus was its ability to build a system using the exact bus cards required for an application. The compact size of a card made the STD bus system more adaptable to various applications than the contemporary computer buses of the mid-1980s such as the S-100 and the SS-50 , because it could use servo control cards along with a ...
The remainder of a 3U single Eurocard is free for user-defined I/O and offers a total of 128 differential contact pairs or 384 contacts. This is significantly more than in 32-bit CompactPCI. 6U double Eurocards provide the entire upper section of the board for user-defined I/O, as do PICMG 2.0 CompactPCI boards of this size.
The PMC standard defines which connector pins are used for which PCI signals; in addition it defines the optional 64 "P4" connector pins for use of arbitrary I/O signals. It enables manufacturers to offer products that are compatible with the well-established PCI bus, but in a smaller and more robust package than standard PCI plug-in cards.
High-pin count (HPC), 400 I/O FPGA Mezzanine Card (FMC) connectors Top: mezzanine card side Bottom: baseboard side. FPGA Mezzanine Card (FMC) is an ANSI/VITA (VMEbus International Trade Association) 57.1 standard that defines I/O mezzanine modules with connection to an FPGA or other device with re-configurable I/O capability.
Unlike the original Eurocard solutions such as VME, which use connectors with a 0.1 inch (2.54 mm) pin spacing, CompactPCI cards use metric connectors with a 2-millimeter pin spacing, designed to the IEC 1076 standard. 3U boards have a 110-pin connector (J1), which carries the 32-bit PCI bus signals, and an optional 110-pin connector (J2 ...

MIL-STD-1397 standard was issued by the United States Department of Defense (DoD) to define "the requirements for the physical, functional and electrical characteristics of a standard I/O data interface for digital data." The MIL-STD-1397 classification types A, B and D apply specifically to the Naval Tactical Data System (NTDS).
While in early development, PCIe was initially referred to as HSI (for High Speed Interconnect), and underwent a name change to 3GIO (for 3rd Generation I/O) before finally settling on its PCI-SIG name PCI Express. A technical working group named the Arapaho Work Group (AWG) drew up the standard. For initial drafts, the AWG consisted only of ...
