A compatibility card is an expansion card for computers that allows it to have hardware emulation with another device. While compatibility cards date back at least to the Apple II family, the majority of them were made for 16-bit computers, often to maintain compatibility with the IBM PC. The most popular of these were for Macintosh systems that allowed them to emulate Windows PCs via NuBus or PCI; Apple had released several such cards themselves. [1]

By other manufacturers

  • Dayna Communications released the MacCharlie for the Macintosh 128K and 512K
  • AST Research released the Mac86 as a PDS expansion for the Macintosh SE, giving it DOS compatibility through a 10 MHz 8086 processor. It was followed up by the Mac286, which added a 286 processor through the Macintosh II's NuBus slots. After AST left the Mac market, the rights to both were sold to Orange Micro.
  • Orange Micro's OrangePC series of cards were the spiritual successor to the Mac86 and Mac286. These cards provided support for 386, 486, and Pentium processors, up to a 400 MHz AMD K6-2 processor in the final model. Orange Micro also released the PCfx!, a cut down OrangePC board with a 200 MHz Pentium soldered on.
  • Reply Corporation's DOS on Mac series of cards added a 486/5x86 (up to 100 MHz) processor and DOS compatibility to Centris, Quadra, Performa, and Power Macintoshes through a PDS expansion; later models supported PCI-based Power Macs and Pentium processors up to 200 MHz. This technology was acquired by Radius in 1997, who began selling the cards under the name "Detente." [3]

The Apple IIe Card is a compatibility card, which through hardware and software emulation, allows certain Macintosh computers to run software designed for the Apple II series of computers. Released in March 1991 for use with the LC family, Apple targeted the card at its widely dominated educational market to ease the transition from Apple II-based classrooms, with thousands of entrenched educational software titles, to Macintosh-based classrooms.

The Power Macintosh G3 is a series of personal computers designed, manufactured, and sold by Apple Computer from November 1997 to August 1999. It represented Apple's first step towards eliminating redundancy and complexity in the product line by replacing eight Power Macintosh models with three: Desktop and Mini Tower models for professional and home use, and an All-In-One model for education. The introduction of the Desktop and Mini Tower models coincided with Apple starting to sell build-to-order Macs directly from its web site in an online store, which was unusual for the time as Dell was the only major computer manufacturer doing this. Apple's move to build-to-order sales of the Power Macintosh G3 also coincided with the acquisition of Power Computing Corporation, which had been providing telephone sales of Macintosh clones for more than two years.

The Macintosh Color Classic is a personal computer designed, manufactured and sold by Apple Computer, Inc. from February 1993 to May 1995. It has an all-in-one design, with a small, integrated 10″ Sony Trinitron display at 512 × 384 pixel resolution. The display is capable of supporting up to thousands of colors with a video memory upgrade.

<span class="mw-page-title-main">Processor Direct Slot</span>

A processor direct slot (PDS) is a slot incorporated into many older Macintosh models that allowed direct access to the signal pins of a CPU, similar to the functionality of a local bus in PCs. This would result in much higher speeds than having to go through a bus layer, such as NuBus, which typically ran at a slower 10 MHz speed.

The Macintosh Quadra 950 is a personal computer designed, manufactured and sold by Apple Computer from March 1992 to October 1995. It replaced the Quadra 900 that was introduced several months earlier, increasing the CPU clock rate of its 68040 CPU from 25 MHz to 33 MHz, and improving the graphics support. The two computers were otherwise identical, including the price. With a Macintosh Processor Upgrade Card installed, this computer is known as the Power Macintosh 950.

The Power Macintosh 7500 is a personal computer designed, manufactured and sold by Apple Computer from August 1995 to May 1996. The 7500 was introduced alongside the Power Macintosh 7200 and 8500 at the 1995 MacWorld Expo in Boston. Apple referred to these machines collectively as the "Power Surge" line, communicating that these machines offered a significant speed improvement over its predecessors. The 7500 introduced a new case design, later dubbed "Outrigger" by Mac enthusiasts. There were two derivative models: the Power Macintosh 7600, identical to the 7500 except for the CPU which was a PowerPC 604 or 604e processor instead of the 7500's 601; and the Power Macintosh 7300, identical to the 7600 but without the video inputs found in both the 7500 and 7600.

The Apple Network Server (ANS) was a line of PowerPC-based server computers designed, manufactured and sold by Apple Computer, Inc. from February 1996 to April 1997. It was codenamed "Shiner" and originally consisted of two models, the Network Server 500/132 and the Network Server 700/150, which got a companion model, the Network Server 700/200 with a faster CPU in November 1996.
