BabyAT

BabyAT refers to a form factor for PC motherboards that was popular in the late 1980s and early 1990s. It was a smaller version of the original AT (Advanced Technology) motherboard standard developed by IBM. The BabyAT standard was designed to fit into smaller computer cases than the full-size AT, making it suitable for more compact desktop computers and early small form factor machines.

Key characteristics of BabyAT motherboards include their physical dimensions, which were reduced compared to the original AT, and a modified layout of expansion slots and connectors to accommodate the smaller size. Despite the reduction in size, BabyAT motherboards generally retained much of the functionality of their larger predecessors, including support for ISA expansion slots, AT keyboard connectors, and standard power supply connections.

The BabyAT form factor played a significant role in the evolution of PC hardware by enabling the development of more space-efficient and potentially more affordable personal computers. As technology advanced and new form factors emerged, such as ATX, BabyAT gradually declined in popularity but laid important groundwork for subsequent motherboard designs. It is rarely encountered in modern computer systems.
