UltraViolet 1.0.0

The first release of UltraViolet, an emulator of the Sun Ultra 5 and Ultra 10 workstations. It runs the original OpenBoot PROM, and Solaris 8, 9 and 10, NetBSD, OpenBSD and Debian GNU/Linux install from their own media and run, with a just-in-time compiler for the UltraSPARC IIi.

• Machine: UltraSPARC IIi at 270 to 440 MHz, up to 1 GB of memory, onboard ATI Rage Pro graphics or a Creator3D in the UPA slot, IDE disk and ATAPI CD-ROM, Ethernet, serial ports, keyboard and mouse, and sound.
• Networking: user-mode (NAT through the host, with port forwarding) on every platform; TAP interfaces on Linux.
• Front end: a window with the machine's screen, menus and settings, and terminal windows for the serial ports, or headless with ttya on the terminal.
