The Apple Macintosh Classic II (also known as the Performa 200) replaced the Macintosh SE/30 in the compact Macintosh line in 1991. Like the SE/30, the Classic II was powered by a 16 MHz Motorola 68030 CPU and 40 or 80 MB hard disk, but in contrast to its predecessor, it was limited by a 16-bit data bus and a 10 MiB memory ceiling.

While the Classic II shares a case with the earlier Classic, architecturally it is more similar to the Macintosh LC. The use of custom ICs, identical to those used in the LC, enabled the Classic II to have a lower component count than older Macs.

The Classic II was the last black-and-white compact Macintosh. Apple discontinued support for the Classic II on January 1, 2001.

	The interrupt (left) and reset (right) buttons protruding from the air vent on the lower left hand side of the Classic II. The interrupt button (also called the programmer's key) is used to access a debugger.
	The Apple ADB keyboard that shipped with the Classic II. On many Macs the large button at the top near the Apple logo was used to power on the machine. However the Classic II did not support this feature. The keyboard contained two ADB connectors. One connected into the back of the Macintosh, the other was used for connecting the mouse or other peripherals. The mouse could be connected to either side for left or right handed use.
