Mac OS 7 is a single-user graphical user interface-based operating system for Macintosh computers. It was introduced on May 13, 1991 by Apple Computer. It succeeded System 6, and was the main Macintosh operating system until it was succeeded by Mac OS 8 in 1997. Features added with the Mac OS 7 release included cooperative multitasking, virtual memory, personal file sharing, an improved user interface, QuickTime, and QuickDraw 3D.

With the release of version 7.6 in 1997, Apple officially renamed the operating system "Mac OS", a name which had first appeared on Mac OS 7.5.1's boot screen. Mac OS 7 was developed for the Motorola 68k processor, but was ported to the PowerPC after Apple adopted the new processor.

Mac OS 7.5.2, released only for the first PCI-based Power Macs, was notable for introducing Apple's new networking architecture, Open Transport.

Power Macintosh 7200 & 9500 software

The Power Macintosh 7200 (Codename: "Catalyst") is a personal computer that is a part of Apple Computer's Power Macintosh series of Macintosh computers. It was introduced in August 1995 as a successor to the Power Macintosh 7100, and was discontinued in favor of the Power Macintosh 7300 in February 1997. The 90 MHz model was also sold in Japan as the Power Macintosh 7215 and the 120 MHz model with bundled server software as the Apple Workgroup Server 7250: additionally, it was available in Europe in an 8100-style case as the Power Macintosh 8200.

The Power Macintosh 9500 (the 132 MHz model is also known as Power Macintosh 9515 in Europe and Japan) is a high-end Macintosh personal computer which was designed, manufactured and sold by Apple Computer from May 1995 until early 1997. It is powered by a PowerPC 604 processor, a second-generation PowerPC chip which was faster than the earlier PowerPC 601 chip. The 180MP and 200 used the enhanced PowerPC 604e processor. The CPU was connected via a daughterboard, and so could be swapped easily. Available were single-processor cards ranging from 120 to 200 MHz, and a dual processor card with two 180 MHz CPUs. It was the first Macintosh to use the PCI standard, with six PCI slots available, with one always needed for the graphics card. The basic design of the logic board, called "Tsunami", was used by various Macintosh clone makers as a reference design. The 9500 was superseded by the Power Macintosh 9600 in February 1997.

Power Macintosh 7500 & 8500 software

The Power Macintosh 7500 was one of the first PCI capable Macs manufactured by Apple Computer. It was released alongside the Power Macintosh 7200, and the Power Macintosh 8500 in October 1995. The 7500 had a PowerPC 601 processor rated at 100 MHz that was replaceable via a daughtercard. It also featured full composite video and s-video input capability, but no output, as the 7500 was designed to be a video conferencing system, not a multimedia editing machine—this was the 8500's task. The 7500 and 7200 featured a unique swing open chassis called "Outrigger" that allowed for easy upgrades, as the entire motherboard was accessible to the user after the hinged drive sleds were opened.

The Power Macintosh 8500 (the 120 MHz model is also known as Power Macintosh 8515 in Europe and Japan) was a high-end Macintosh personal computer designed, manufactured and sold by Apple Computer from 1995 until 1997. Billed as a high-end graphics computer, the Power Macintosh 8500 was also the first Macintosh to ship with a replaceable daughtercard. Though slower than the 132 MHz Power Macintosh 9500, it featured several audio and video (S-Video and composite video) in/out ports not found in the 9500.

PowerBook 5300, 2300, 190, and 500 Upgrade Card software

The PowerBook 5300 series was the first generation of PowerBook laptops manufactured by Apple Computer to use the PowerPC processor. Released in August 1995, these PowerBooks were notable for being the first to feature hot-swappable expansion modules for a variety of different units such as ZIP drives; PC card slots as standard; and an infrared communication port. In common with most preceding Macintosh portables, SCSI, Serial, and ADB ports were available as standard. An internal expansion slot was also available for installing a variety of modules including Ethernet and video cards to drive a second monitor in mirroring or dual-screen modes.

The PowerBook Duo was a line of small subnotebooks manufactured and sold by Apple Computer from 1992 until 1997 as a more compact companion to the PowerBook line. Improving upon the PowerBook 100's portability (its immediate predecessor and Apple's third smallest laptop), the Duo came in seven different models. They were the Duo 210, 230, 250, 270c, 280, 280c, and 2300c, with the 210 and 230 being the earliest, and 2300c being the final incarnation before the entire line was dropped in early 1997.

The PowerBook 190 and its companion PowerBook 190cs are laptop computers manufactured by Apple Computer as part of their PowerBook brand, introduced to the market in August 1995. The two models differ only in their screen: The 190 had a 9.5" greyscale display, while the 190cs featured a 10.4" color display. Apple's target sales audience for this model was the college student in need of a no-frills portable computer. In terms of hardware, along with the PowerBook 150, the 190 has much in common with Apple's "professional" laptop of the same period, the PowerBook 5300 series. In exchange for the cheaper price point (approximately $2200 US compared to over $6000 for the cutting-edge PowerBook 5300ce), the 190 was equipped with a passive matrix LCD rather than a crisper active matrix screen. More significantly, while the 5300s ran PowerPC 603e processors at 100 or 117 MHz, the 190 had only a Motorola 68LC040 clocked at 33 MHz - in fact, the 190s were the last Macintoshes to use an 68k CPU. However, Apple offered a PPC upgrade for the 190, a heavily marketed selling point for all new 68040 Macs at the time. In addition, a rather cramped 500 MB IDE hard drive was standard, and factory models shipped with Mac OS 7.5.2. It is the only one of the 100 series PowerBooks that does not use the original 140 case design, thus was the only one to include a 68040 processor, a trackpad rather than the standard trackball, and along with the 150 the only ones to provide for more than 14MB RAM expansion and larger, less-expensive IDE drives. The 190 was the de facto replacement for the PowerBook 500 series, which was completely discontinued with the introduction of the 5300 and the only 68040-based PowerBook Apple offered.
