Nysoni Zeta

Zeta (1977-1985)
The Zeta was released as early as 1977. It is not known exactly when it was released to the consumer market, but the system was not seen on the market again some time after 1985. The computer was specially designed to run on the Nysoni operating system. All of Nysoni's computers were on a single operating system until 1996.

Zeta II (1982-1997)
The Zeta II (or Zeta 2) was released in 1982. It ran on a much more enhanced operating system, and for the first time a printer was shipped with the package. It was so successful as the printing mechanism allowed users to print off the computer. The Zeta II was that successful, Nysoni released a remastered version in 1995 to work with the release of the Epsilon system. All Zeta II models were discontinued in 1997 and internet services for the Zeta II were shut down in 2004.

Zeta Office (1986-1990)
The Zeta Office was designed for businesses who were after Nysoni computers that were capable of performing such tasks. They were never released to the consumer market, and order services for this line was stopped some time around 1990.

Zeta III (1991-1999)
The Zeta III (or Zeta 3) was not as well received as the other two systems. New accessories were released, but they were sold separately, and users had to purchase licences in order to use them. Nysoni eventually discontinued this service in 1993, but because of poor sales, and the eventual evolution of the Zeta Lumi, Nysoni discontinued the Zeta III by 1999.

Zeta Lumi (1994-2010)
The Zeta Lumi went through numerous software and hardware changes until Nysoni pulled it from the market in early 2010. It was so successful because of its internet access, and that it was the first Nysoni Epsilon-supported computer. When Epsilon 8, the last Epsilon operating system release was discontinued in 2010, Nysoni subsequently took the Zeta Lumi with it. Nysoni then announced that it would be retiring the Zeta name in 2011. All Zeta services were subsequently shut down by the end of the year.

Zeta Lumi Portable (1995-2010)
Nysoni's first consumer laptop was the Zeta Lumi Portable, which was designed to work like a Zeta Lumi except it could be carried around. Its heavy weight however forced it to be recalled in 1998 to a thinner model, which Nysoni kept slimming down until the last Lumi Portable in 2005. Nysoni discontinued all Zeta services in 2010, which resulted in the discontinuation of the Zeta Lumi Portable.
