SPECIFICATIONS — PCI-104
The ISA architecture bus has long been a popular choice for embedded applications. With the publication of the PC/104 standard in 1992, this bus architecture was available on a small, rugged form factor which has since become an industry standard. As technological requirements advanced, a need began to arise for a higher performance bus throughput. This is especially true when it comes to graphics devices as well as other high-speed I/O devices such as networks. The PC/104 Consortium met this challenge by incorporating a PCI bus on the PC/104 form factor, which became to be known as PC/104-Plus. This architecture provides a link to versatile legacy hardware while meeting the high-speed requirements for present and future hardware.
To accommodate the gradual replacement of ISA bus devices with PCI devices, the PCI-104 was approved by the PC/104 Consortium. PCI-104 is a PCI-only architecture that accommodates the advances of PCI devices in a small rugged form factor.
This document supplies the mechanical and electrical specifications for the "PCI-104" which has the advantage of the high-speed PCI bus.
