Delta-S

Delta-S is a Christian industrial / progressive trance band formed in Camarillo, California in 1995. Band members currently include Lyte, who writes and produces a bulk of the work, and Lucien, who tests the material's emotional value and authenticity.

History

Delta-S was initially formed in 1995 by artists Moe and Lyte, under the name Entropy. Later that year, the band changed their name to Delta-S. The name refers to a change in entropy (Delta So), and conceptually refers to the band's attempts at speeding up, slowing down, or stopping the process of entropy in the listener. In 1996, Jim Prosser joined the band. Work began on the production of their first album, including some collaboration with the band Calcutta and artists Duke and Joshua Vosper. The album was never released, and Delta-S disbanded in 1998.

After disbanding, Lyte continued the project as a solo effort. In 1999 production for the second Delta-S album, And Sometimes..., began. This album was also unreleased. In 2000 the band adopted a new member, Lucien, and work started on a third album, Chasm. This was released as the band's debut album in March 2005, under a created record label entitled WindM Records, titled Chasm (Volume 0). The album was later re-released as Chasm (Volume 1) in May that year.

Entropy

In thermodynamics, entropy (usual symbol S) is a measure of the number of specific realizations or microstates that may realize a thermodynamic system in a defined state specified by macroscopic variables. Entropy is commonly understood as a measure of molecular disorder within a macroscopic system. According to the second law of thermodynamics the entropy of an isolated system never decreases. Such a system spontaneously evolves towards thermodynamic equilibrium, the state with maximum entropy. Systems that are not isolated may decrease in entropy, provided they increase the entropy of their environment by at least that same amount. Since entropy is a state function, the change in the entropy of a system is the same for any process that goes from a given initial state to a given final state, whether the process is reversible or irreversible. However, irreversible processes increase the combined entropy of the system and its environment.

The change in entropy (ΔS) of a system was originally defined for a thermodynamically reversible process as

List of ZX Spectrum clones

The following is a list of clones of Sinclair Research's ZX Spectrum home computer:

Official clones

The only official clones of the Spectrum were made by Timex. There were three models developed, only two of which were released:

Timex Sinclair 2068

A significantly more sophisticated machine than the original Spectrum. The most significant changes were the addition of a cartridge port, an AY-3-8912 sound chip and an improved ULA giving access to better graphics modes. The TS2068 was marketed in the United States, while very similar machines were marketed in Portugal and Poland as the Timex Computer 2068 (TC2068) and Unipolbrit Komputer 2086 (UK2086) respectively. A small amount of TC2068 were also sold in Poland.

Timex Computer 2048

A machine similar to the Spectrum 48K, but with the improved ULA from the TC2068 allowing access to the improved graphics modes. Marketed only in Portugal and Poland.

Timex Sinclair 2048

A never released variant of the TS2068 with 16 KB of RAM.
