Baby AT


The Baby AT was the standard in the PC industry from roughly 1993-1997.

Some issues with the AT and Baby AT design is the location of the features on the board. The CPU socket is placed so that it may interfere with longer bus cards. In some designs the memory sockets are similarly placed. This can limit the amount and selection of peripheral cards you can install. Also the IO ports are separate and mounted on the case and connected to pin-outs on the motherboard. These are usually located near the floppy and IDE pin-outs and can result in quite a jumble of ribbon cables.
