At the beginning of the 90s the demand for electronic goods such as PCs was huge in all sectors. The performance of the embedded microcomputer application grew rapidly, as did, unfortunately, the problem of creating a low-cost connection between two motherboards. Industry had to find a way to connect at least two motherboards together without needing to use a card cage or a backplane. In addition, the components had also to be easily separated or replaced at any time.
Although PC/104 modules have been manufactured since 1987, a formal specification was not published until 1992, when the PC/100 Embedded Consortium designed the first release of a mechanical and electrical specification of a connector that fully supported an 8bit/16/bit ISA bus. Since then, interest in PC/104 has skyrocketed, with over a hundred different PC/104 modules introduced by more than three dozen manufacturers. Like the original PC bus itself, PC/104 is the expression of an existing de facto standard, rather than being the invention and design of a committee. In 1992, the IEEE began a project to standardize a reduced form-factor implementation of the IEEE P996 (draft) specification for the PC and PC/AT buses, for embedded applications. The PC/104 Specification has been adopted as the base document for this new IEEE draft standard, called the P996.1 Standard for Compact Embedded-PC Modules. The advent of the PC104-Plus specification likewise supported the PCI bus.
