Single-board PC's were at one time viewed as "dyna-micro" supported by the Intel C8080A central processor and Intel's 1st EPROM (Erasable Programmable Read-Only Memory) chip. This revolutionary chip was projected to keep its data when the power was turned off. Rebranded by E&L Instruments in 1976, the EPROM got recognized as the BugBook 8080 micro-computer.

Contrary to the common intention, PC embedded SBC systems were explicitly configured to run a dedicated role repeatedly, with real-time computing constraints. Embedded single-board computers are piece of a bigger device that includes computer hardware and mechanic parts. By comparing, the PC was projected to be multi-functional. Nowadays, the closest-fitting thing we have to an embedded system falls into the hand-held microcomputer class, that is, a personal data manager or PIM. Even these computers can not be counted as genuinely embedded as they provide multifunctional capabilities, right like PCs.

When PCs came into their own, there was a break away from single-board central processors. PC Machines are now run from a CPU board with add-ons to gain versatility. These plug-in boards included serial ports, hard drive and graphics controllers, parallel interface, IDE and SATA (Serial Advanced Technology Attachment), a PC bus linking heavy disk optical drives, RAID incorporation for backup, and, at last, the power to switch devices such as DVD drives.

While embedded single-board processing is no more applied in the PC field, there are still a mass usages for embedded SBCs in the communicating, energy, point of data/sale, defense force and aerospace, industrialized automation, medical and transport industries. There is a remarkable portfolio of products and services that have sophisticated and now use this technology providing results that are both ready-made and custom masterminded embedded PC modules, boards and blades to standard computing systems that match nowadays demands and are expandable for forthcoming demands.

Embedded SBC systems have a lot of benefits like instant accessibility and about no time-to-market. Because their ports and functionalities are on board, they are regular add-ons that incorporate a fast system set-up. Modifying out SBC systems is minimally unsafe and affordable as the chassis, accessories, and attachment points rarely change. For numerous editions there is a selection of fan less, low-power, cache less OS's that have a low profile and low power usage.
