Macintosh Classic II

The Macintosh Classic II (also sold as the Performa 200, known as “Performa 1” in Europe, “Classic Mono” in Australia & New Zealand and as "Deluxe II" or "Deluxe 2" in Japan and other parts of Asia) is a personal computer designed, manufactured and sold by Apple Computer, Inc. from October 1991 to September 1993. Like the Macintosh SE/30 it replaces, 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 (the SE/30 had a 32-bit data bus) and a 10 MB memory ceiling. The slower data bus resulted in the Classic II being 30% slower than the SE/30.[1]

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. Unlike the LC and the SE/30 before it, the Classic II does not have an internal Processor Direct Slot, making it the first slotless desktop Macintosh since the Macintosh Plus.

The Classic II was one of the three machines Apple repackaged as a Macintosh Performa when the brand was introduced in September 1992.[2] Called the "Performa 200", it was sold with the same specifications as the original Classic II, with the addition of a speaker grille on the left side for enhanced sound. A number of changes to the packaged software were included, such as the At Ease desktop alternative which aimed to provide a simpler user interface than the standard Macintosh Finder. The exact software included tended to vary from one retailer to the next. It was initially offered at a retail price of about $1,250 USD.[2]

The Classic II is the last black-and-white compact Macintosh, and the last desktop Macintosh to include an external floppy disk drive port. Apple discontinued support for the Classic II on January 1, 2001.

The Classic II has a 50-pin internal expansion slot intended for either an FPU co-processor or additional ROM. The socket is not designed to be used for any other purpose and is not suitable for use as a general expansion slot. Apple never produced an expansion card of any kind for this slot,[6] although at least one third-party FPU was available: the FastMath Classic II by Applied Engineering.[7] and Sonnet offered a synchronous (16MHz) and asynchronous (50MHz) 68882 FPU.

 Back of the Classic II
 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.
