The ISA bus architecture has long been a popular choice for embedded applications, and the implementation of the PC/104 standard in 1992 made the ISA bus architecture available in a small, stackable, rugged form factor. Since then, PC/104 has become an industry standard. As technological requirements became more complex, a need arose for higher bus throughput performance. The PC/104 consortium developed PC/104-Plus™ and PCI-104™ specifications on the 104™ form factor. The stackable connectors and asymmetric corner mounting holes create a modular system that is both rugged and compact.
PC/104 is the original specification. It defines the 104 form factor at 3.550” x 3.775” (90.17 x 95.89 mm) with a stacking ISA bus. The specification is for 8-bit (XT) and 16-bit (AT) versions.
The PC/104-Plus standard added PCI buses to PC/104 on the 104 form factor. A transfer rate of 132 MB/s made high-speed processing possible in rugged embedded systems while the ISA bus allowed for the use of embedded modules to develop extensive infrastructure.
