The PC532 was a "home-brew" microcomputer design created by George Scolaro and Dave Rand in 1989-1990, based on the National Semiconductor NS32532 microprocessor (a member of the NS320xx series). Full hardware documentation for the design, including schematics and PAL programming data, was made freely available, and a short run (around 200) of motherboard PCBs were produced for hobbyists to populate and assemble into fully functional systems.
The following operating systems were ported to the PC532:
MINIX is a Unix-like operating system based on a microkernel architecture. Since version 2.0, it has been Portable Operating System Interface (POSIX) compliant.
PowerPC is a reduced instruction set computer (RISC) instruction set architecture (ISA) created by the 1991 Apple–IBM–Motorola alliance, known as AIM. PowerPC, as an evolving instruction set, has been named Power ISA since 2006, while the old name lives on as a trademark for some implementations of Power Architecture–based processors.
The NS32000, sometimes known as the 32k, is a series of microprocessors produced by National Semiconductor. The first member of the family came to market in 1982, briefly known as the 16032 before becoming the 32016. It was the first general-purpose microprocessor on the market that used 32-bit data throughout: the Motorola 68000 used 32-bit data but had a 16-bit ALU and thus took twice as long perform many operations. However, the 32016 contained many bugs and often could not be run at its rated speed. These problems, and the presence of the otherwise similar 68000 which had been available since 1980, led to little use in the market.
A disk array controller is a device that manages the physical disk drives and presents them to the computer as logical units. It almost always implements hardware RAID, thus it is sometimes referred to as RAID controller. It also often provides additional disk cache.
XNU is the computer operating system (OS) kernel developed at Apple Inc. since December 1996 for use in the Mac OS X operating system and released as free and open-source software as part of the Darwin OS, which in addition to macOS is also the basis for the Apple TV Software, iOS, iPadOS, watchOS, visionOS, and tvOS OSes.
HP 9000 is a line of workstation and server computer systems produced by the Hewlett-Packard (HP) Company. The native operating system for almost all HP 9000 systems is HP-UX, which is based on UNIX System V.
The SPARCstation 1 is the first of the SPARCstation series of SPARC-based computer workstations sold by Sun Microsystems. The design originated in 1987 by a Sun spin-off company, Unisun, which was soon re-acquired. The SPARCstation 1 has a distinctive slim enclosure and was first sold in April 1989, with Sun's support ending in 1995.
The O2 is an entry-level Unix workstation introduced in 1996 by Silicon Graphics, Inc. (SGI) to replace their earlier Indy series. Like the Indy, the O2 uses a single MIPS microprocessor and was intended to be used mainly for multimedia. Its larger counterpart is the SGI Octane. The O2 was SGI's last attempt at a low-end workstation.
The MIPS Magnum was a line of computer workstations designed by MIPS Computer Systems, Inc. and based on the MIPS series of RISC microprocessors. The first Magnum was released in March, 1990, and production of various models continued until 1993 when SGI bought MIPS Technologies. SGI cancelled the MIPS Magnum line to promote their own workstations including the entry-level SGI Indy.
The NEC RISCstation was a line of computer workstations made by NEC in the mid-1990s, based on MIPS RISC microprocessors and designed to run Microsoft Windows NT. A series of nearly identical machines were also sold by NEC in headless configuration as the RISCserver series, and were intended for use as Windows NT workgroup servers.
The Jazz computer architecture is a motherboard and chipset design originally developed by Microsoft for use in developing Windows NT. The design was eventually used as the basis for most MIPS-based Windows NT systems.
The SRM firmware is the boot firmware written by Digital Equipment Corporation (DEC) for computer systems based on the DEC Alpha microprocessor. SRM are the initials of (Alpha) System Reference Manual, the publication detailing the Alpha AXP architecture and which specified various features of the SRM firmware.
The SPARCstation 10 is a workstation computer made by Sun Microsystems. Announced in May 1992, it was Sun's first desktop multiprocessor. It was later replaced with the SPARCstation 20.
The Sun-2 series of UNIX workstations and servers was launched by Sun Microsystems in November 1983. As the name suggests, the Sun-2 represented the second generation of Sun systems, superseding the original Sun-1 series. The Sun-2 series used a 10 MHz Motorola 68010 microprocessor with a proprietary Sun-2 Memory Management Unit (MMU), which enabled it to be the first Sun architecture to run a full virtual memory UNIX implementation, SunOS 1.0, based on 4.1BSD. Early Sun-2 models were based on the Intel Multibus architecture, with later models using VMEbus, which continued to be used in the successor Sun-3 and Sun-4 families.
The Sun386i is a discontinued hybrid UNIX workstation/PC compatible computer system produced by Sun Microsystems, launched in 1988. It is based on the Intel 80386 microprocessor but shares many features with the contemporary Sun-3 series systems.
The SPARCstation 2, or SS2 is a SPARC workstation computer sold by Sun Microsystems. It is based on the sun4c architecture, and is implemented in a pizza box form factor.
Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. KVM requires a processor with hardware virtualization extensions, such as Intel VT or AMD-V. KVM has also been ported to other operating systems such as FreeBSD and illumos in the form of loadable kernel modules.
The Digital Personal Workstation, code named "sports car", is a family of entry-level to mid-range workstation computers developed and manufactured by Digital Equipment Corporation (DEC). These workstations are based on the DEC Alpha and Intel Pentium Pro or Pentium II microprocessors. Members of this family can run the Digital UNIX, OpenVMS, and Windows NT operating systems. The i-Series, based on Pentium Pro, was introduced first, on September 23, 1996.
NetBSD is a free and open-source Unix operating system based on the Berkeley Software Distribution (BSD). It was the first open-source BSD descendant officially released after 386BSD was forked. It continues to be actively developed and is available for many platforms, including servers, desktops, handheld devices, and embedded systems.
