The Q-bus (also known as the LSI-11 Bus) was one of several bus technologies used with PDP and MicroVAX computer systems manufactured by the Digital Equipment Corporation of Maynard, Massachusetts.

The Q-bus was a less expensive version of Unibus using multiplexing so that address and data signals shared the same wires. This allowed both a physically smaller and less-expensive implementation of essentially the same functionality.

Over time, the physical address range of the Q-bus was expanded from 16 to 18 and then 22 bits. Block transfer modes were also added to the Q-bus.

Like the Unibus before it, the Q-bus used:

Memory-mapped I/O means that data cycles between any two devices, whether CPU, memory, or I/O devices, used the same protocols. On the Unibus, a range of physical addresses were dedicated for I/O devices. The Q-bus simplified this design by providing a specific signal (originally called BBS7, Bus Bank Select 7 but later generalized to be called BBSIO, Bus Bank Select I/O) that selected the range of addresses used by the I/O devices.

Charlie Parr is an American country blues musician, born in Austin, Minnesota, United States. He started his music career in Duluth, Minnesota.

Parr played at the 2011 Pickathon Music Festival in Oregon.

Born in Johannesburg, South Africa, and raised in Philadelphia, Isakov later moved to Colorado. Isakov's voice and guitar style leave a humble presence that has spawned a burgeoning fan base.

Isakov has performed throughout North America and Europe; and has appeared at music festivals such as South by Southwest, Falcon Ridge Folk Festival, Rocky Mountain Folks Fest, and Telluride Bluegrass Festival.In 2011, Isakov's songs were featured in film and television productions, including his track "If I Go, I'm Goin'", which was heard in the fourth season of television show Californication on Showtime; and "Big Black Car", which was featured in McDonald's Christmas commercial in Canada.

Kelly Joe Phelps (born October 5, 1959, Sumner, Washington, United States) is an American musician and songwriter. His music has been characterized as a mixture of delta blues and jazz.

Kelly Joe Phelps grew up in Sumner, Washington, a blue-collar and farming town. He learned country and folk songs, as well as drums and piano, from his father. He began playing guitar at age twelve.

Phelps concentrated on free jazz and took his cues from musicians like Ornette Coleman, Miles Davis, and John Coltrane. He spent 10 years playing jazz, mostly as a bass player. He refers to his "conversion" to a blues musician when he began listening to acoustic blues masters like Fred McDowell and Robert Pete Williams.

Initially gaining notice for his solo lapstyle slide guitar playing, which he played by laying the instrument flat and fretting it with a heavy steel bar, he has incorporated more ensemble work in his later albums. Inspired by the birth of his daughter Rachel in 1990, Phelps began writing songs. He began singing and released his critically praised debut, Lead Me On, in 1995. This album showcased Phelps' craft, and as well as his own songs, he tackled traditional numbers such as "Motherless Children" and "Fare Thee Well."

Joan of Arc, nicknamed "The Maid of Orléans" (French: Jeanne d'Arc,IPA: [ʒan daʁk]; ca. 1412 – 30 May 1431), is a folk heroine of France and a Roman Catholic saint. A peasant girl born in what is now eastern France who claimed divine guidance, she led the French army to several important victories during the Hundred Years' War, which paved the way for the coronation of Charles VII of France. She was captured by the Burgundians, transferred to the English in exchange for money, put on trial by the pro-English Bishop of Beauvais Pierre Cauchon for charges of "insubordination and heterodoxy," and was burned at the stake for heresy when she was only 19 years old.

Twenty-five years after her execution, an inquisitorial court authorized by Pope Callixtus III examined the trial, pronounced her innocent, and declared her a martyr. Joan of Arc was beatified in 1909 and canonized in 1920. She is – along with St. Denis, St. Martin of Tours, St. Louis IX, and St. Theresa of Lisieux – one of the patron saints of France. Joan said that she had visions from God that instructed her to recover her homeland from English domination late in the Hundred Years' War. The uncrowned King Charles VII sent her to the siege of Orléans as part of a relief mission. She gained prominence when she overcame the dismissive attitude of veteran commanders and lifted the siege in only nine days. Several additional swift victories led to Charles VII's coronation at Reims and settled the disputed succession to the throne.
