The Ultra 1 is a family of Sun Microsystems workstations based on the 64-bit UltraSPARC microprocessor. It was the first model in the Ultra series of Sun computers, which succeeded the SPARCstation series. It launched in November 1995 alongside the MP-capable Ultra 2 and shipped with Solaris 2.5. It is capable of running other operating systems such as Linux and BSD.
The Ultra 1 was available in a variety of specifications. The Ultra 1 Creator3D 170E launched with a list price of US$27,995(equivalent to $49,800 in 2021) - along with the Ultra 1 Model 140, and Ultra 1 Creator 170E. [1]
Three different CPU speeds were available: 143 MHz (Model 140), 167 MHz (Model 170) and 200 MHz (Model 200).
Model numbers with an E suffix (Sun service code A12, code-named Electron) had two instead of three SBus slots, and added a UPA slot to allow the use of an optional Creator framebuffer. In addition, the E models had Wide SCSI and Fast Ethernet interfaces, in place of the narrow SCSI and 10BASE-T Ethernet of the standard Ultra 1 (service code A11, code-named Neutron).
The Ultra 1 uses 200-pin 5V ECC 60 ns SIMMs in pairs, the same memory used in the SPARCstation 20.
Similar Sun machines were the Netra i 1 servers which had the same chassis and the UltraServer 1/Ultra Enterprise 1 servers .
SBus is a computer bus system that was used in most SPARC-based computers from Sun Microsystems and others during the 1990s. It was introduced by Sun in 1989 to be a high-speed bus counterpart to their high-speed SPARC processors, replacing the earlier VMEbus used in their Motorola 68020- and 68030-based systems and early SPARC boxes. When Sun moved to open the SPARC definition in the early 1990s, SBus was likewise standardized and became IEEE-1496. In 1997 Sun started to migrate away from SBus to the Peripheral Component Interconnect (PCI) bus, and today SBus is no longer used.
Sun Enterprise is a range of UNIX server computers produced by Sun Microsystems from 1996 to 2001. The line was launched as the Sun Ultra Enterprise series; the Ultra prefix was dropped around 1998. These systems are based on the 64-bit UltraSPARC microprocessor architecture and related to the contemporary Ultra series of computer workstations. Like the Ultra series, they run Solaris. Various models, from single-processor entry-level servers to large high-end multiprocessor servers were produced. The Enterprise brand was phased out in favor of the Sun Fire model line from 2001 onwards.
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 SPARCstation, SPARCserver and SPARCcenter product lines are a series of SPARC-based computer workstations and servers in desktop, desk side (pedestal) and rack-based form factor configurations, that were developed and sold by Sun Microsystems.
The Sun Ultra series is a discontinued line of workstation and server computers developed and sold by Sun Microsystems, comprising two distinct generations. The original line was introduced in 1995 and discontinued in 2001. This generation was partially replaced by the Sun Blade in 2000 and that line was in itself replaced by the Sun Java Workstation—an AMD Opteron system—in 2004. In sync with the transition to x86-64-architecture processors, in 2005 the Ultra brand was later revived with the launch of the Ultra 20 and Ultra 40, albeit to some confusion, since they were no longer based on UltraSPARC processors.
The SPARCstation 20 or SS20 is a discontinued Sun Microsystems workstation introduced in March 1994 based on the SuperSPARC or hyperSPARC CPU. It is one of the last models in the SPARCstation family of Sun "pizza box" computers, which was superseded by the UltraSPARC design in 1995.
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.
SPARCstation 5 or SS5 is a workstation introduced by Sun Microsystems in March 1994. It is based on the sun4m architecture, and is enclosed in a pizza-box chassis. Sun also offered a SPARCserver 5 without a framebuffer. A simplified, cheaper version of the SS5 was released in February 1995 as the SPARCstation 4. Sun also marketed these same machines under the "Netra" brand, without framebuffers or keyboards and preconfigured with all the requisite software to be used as web servers. An estimated 400,000+ SPARCstation 5s were sold.
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.
The Ultra 5 and Ultra 10 are 64-bit Sun Microsystems workstations based on the UltraSPARC IIi microprocessor available since January 1998 and last shipped in November 2002. They were introduced as the Darwin line of workstations.
The Sun Microsystems Ultra 80 is a computer workstation that shipped from November 1999 to 2002.
Sun4d is a computer architecture introduced by Sun Microsystems in 1992. It is a development of the earlier Sun-4 architecture, using the XDBus system bus, SuperSPARC processors, and SBus I/O cards. The XDBus was the result of a collaboration between Sun and Xerox; its name comes from an earlier Xerox project, the Xerox Dragon. These were Sun's largest machines to date, and their first attempt at making a mainframe-class server.
The SPARCclassic is a workstation introduced by Sun Microsystems in November 1992. It is based on the sun4m architecture, and is enclosed in a lunchbox chassis. It shares the code name Sunergy with the SPARCclassic X, SPARCstation LX, and SPARCstation ZX. It was replaced by the SPARCstation 4 in February 1994.
The SPARCstation LX is a workstation that was designed, manufactured, and sold by Sun Microsystems. Introduced in November 1992, it is based on the sun4m architecture and enclosed in a lunchbox chassis. It shares the code name Sunergy with the low-end range of SPARCclassic, SPARCclassic X, and SPARCstation ZX.
The SPARCstation IPC is a workstation sold by Sun Microsystems, introduced July 1990. It is based on the sun4c architecture, and is enclosed in a lunchbox chassis.
The SPARCstation IPX is a workstation that was sold by Sun Microsystems, introduced July 1991. It is based on the sun4c architecture, and is enclosed in a lunchbox chassis.
The Ultra 60 is a fairly large and heavy computer workstation in a tower enclosure from Sun Microsystems. The Ultra 60 was launched in November 1997 and shipped with Solaris 7. It was available in several specifications.
The Ultra 30 is a family of Sun Microsystems workstations based on the UltraSPARC II microprocessor. It was the first Sun workstation to use the industry-standard PCI bus instead of Sun's proprietary SBus, and is a member of the Sun Ultra series. It launched in July 1997 and shipped with Solaris 2.6. The Ultra 30 reached its end-of-life in May 1999.
