Wilmington, North Carolina once had a thriving Black middle class and an elected interracial government. In 1898 white supremacists used violence to overthrow that government, kill Black residents and drive many others from the city.

Sun Java Workstation was a line of computer workstations sold by Sun Microsystems from 2004 to 2006, based on the AMD Opteron microprocessor family. The range supplanted the earlier Sun Blade workstation line. These were the first x86-architecture workstations Sun had produced, other than the short-lived Sun386i in the late 1980s.
Supported operating systems were Solaris, Red Hat Enterprise Linux WS or SUSE Linux Enterprise Server 9. The Java Workstation name alluded to the workstations being intended to run Sun's Java Desktop System, a GNOME-based desktop environment.
The Java Workstation series was replaced by Ultra 20 and Ultra 40 workstations from 2005 onwards.

Sun Java Workstation was a line of computer workstations sold by Sun Microsystems from 2004 to 2006, based on the AMD Opteron microprocessor family. The range supplanted the earlier Sun Blade workstation line. These were the first x86-architecture workstations Sun had produced, other than the short-lived Sun386i in the late 1980s. Supported operating systems were Solaris, Red Hat Enterprise Linux WS or SUSE Linux Enterprise Server 9. The Java Workstation name alluded to the workstations being intended to run Sun's Java Desktop System, a GNOME-based desktop environment. The Java Workstation series was replaced by Ultra 20 and Ultra 40 workstations from 2005 onwards.
The Sun Blade series is a computer workstation line based on the UltraSPARC microprocessor family, developed and sold by Sun Microsystems from 2000 to 2006. The range replaced the earlier Sun Ultra workstation series. The Sun Blade 1000, introduced in October 2000, was the first system to use Fireplane as the interconnect between its single or dual processors and the I/O subsystem, a few months ahead of its use in the new Sun Fire server product line. The 1500/2500 series came in two variants, the earlier "red" series, and the later "silver" series. The "silver" series were enhanced versions of the "red" series - a faster CPU being the key differentiator. The Sun Blade series was supplanted by the Sun Java Workstation line in 2004. The product line's name was not a reference to "blade server" systems, a term not yet in common use in 2000. In 2006, Sun did introduce an unrelated "Sun Blade" blade server product line.
The Sun Ultra 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.
SoftPC is a software emulator of x86 hardware. It was developed by Rod MacGregor, Henry Nash & Phil Bousfield, following the founding of Insignia Solutions in 1986 by MacGregor, with "about a dozen people who had left the CAD/CAM workstation specialist Computervision", believing in a market opportunity for an independent CAD/CAM consultancy. Originally a side project, SoftPC quickly became the main focus for the company, running PC software on workstations. Originally developed on SPARCstations, the first customer to license the software was Intergraph whose workstation had a proprietary processor architecture. Available originally on UNIX workstations to run MS-DOS, the software was ported to the Macintosh in 1987, and later gained the ability to run Microsoft Windows software. Besides Mac OS, supported platforms included SGI IRIX, Sun Solaris, HP-UX, IBM AIX, NeXTSTEP, Motorola 88000, OpenVMS on VAX and DEC Alpha systems, DEC ULTRIX, and others. Bundles of SoftPC with Windows (3.x, 95, 98) were called SoftWindows, although it was possible to install Windows into the basic SoftPC environment along with some special utilities provided by Insignia to achieve the same effect. The introduction of Windows and applications running in that environment, as opposed to DOS, changed the underlying conditions for emulators, and Insignia's SoftWindows product was described, in comparison to SoftPC, as "a complete redesign, mandated by the size and complexity of Windows programs". The execution characteristics, described as "narrow and deep" in DOS applications, were instead "broad and shallow" in Windows applications, making it more difficult to identify sections of code for translation to the native architecture of the computer running the emulator. Insignia entered into a development agreement with Microsoft giving the company access to Windows source code. This agreement covered the product then known as Windows 4 as well as Windows NT, on which Microsoft was seeking to support compatibility for Intel architecture binaries on RISC architecture systems. When Microsoft released Windows NT it included a subsystem ("WOW" - Windows on Windows, later NTVDM) for running virtualized 16-bit Windows (x86) programs. However, it had also made changes to Windows to allow it to run on alternative processors (Alpha, PowerPC), and for these an emulation layer was needed for programs compiled for Intel processors. Customized versions of Insignia's core emulation system were produced to this end, but the alternative NT architectures never became widely used. Beginning in 1996, Insignia commanded the niche for this product area, but it soon faced heavy competition from Connectix with their Virtual PC product. Insignia sold the product line to FWB Software in October 1999 in order to focus on supplying implementations of Java for the mobile device market. FWB continued to sell SoftWindows until March 2001. FWB Software also marketed a separate version of the software that did not include a bundled copy of Windows, called RealPC, until 2003. Unlike most emulators, the SoftWindows product used recompiled Windows components to improve performance in most business applications, providing almost native performance (but this meant that, unlike SoftPC, SoftWindows was not upgradable).
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
