SRT, Inc.
SRT, Inc., doing business as Covox, Inc., was a small, privately owned American technology company active from 1975 to 1994. The company released a number of sound-generating devices for microcomputers and personal computers from the 1980s to the 1990s. They are perhaps best known for the Speech Thing, a digital-to-analog converter that plugs into a parallel port of the IBM Personal Computer. Covox was originally based in Southern California but moved their headquarters to Eugene, Oregon, in the early 1980s. History SRT, Inc., was founded by Larry Stewart in Southern California in 1975. Stewart had previously worked in the aerospace industry into the 1960s, where he got the idea for Av-Alarm, a sound-generating device intended to scare off birds from outside locations such as vegetable crops and vineyards. SRT relocated to Eugene, Oregon, in 1982, Stewart finding Oregon to be a cheaper state in which to conduct his business. Around this time, he hired his sons Mike Stewart and Br ...

Covox Speech Thing
The Covox Speech Thing is an external digital-to-analog converter (DAC) that plugs into the parallel printer port of a PC. It converts 8-bit digital sound using a simple R-2R resistor ladder into an analog signal output. The Speech Thing was introduced on December 18, 1987 by Covox, Inc. of Eugene, Oregon, for about US$70 () and priced US$79.95 as of 1989. People soon started to build their own (DIY) variants, since its communication protocol and DAC is simple and only requires soldering a few cheap parts. The novelty of its patent "Parallel port pass-through digital to analog converter" (filed in 1987, granted in 1989) wasn't specifically the use of a resistor ladder as a DAC, but rather the patent's discussion is around its ease of plugging into the parallel port and how its resistor ladder design didn't block other devices from using the parallel port. , as sound cards were still very expensive at that time. The plug was also quite popular in the demoscene. An inherent ...

Pearson Airpark
Pearson Field also once known as Pearson Airpark, is a city-owned municipal airport located one mile (2 km) southeast of the central business district of Vancouver, a city in Clark County, Washington, United States. Pearson Field is the oldest continuously operating airfield in the Pacific Northwest and one of the two oldest continuously operating airfields in the United States, receiving recognition in 2012 as an American Institute of Aeronautics and Astronautics historic aerospace site. Pearson Field's history began with the landing of a Baldwin airship, piloted by Lincoln Beachey, upon the polo grounds of the Vancouver Barracks in 1905. It is located in the Fort Vancouver National Historic Site immediately to the east of the reconstructed fort. Primarily used for general aviation, the airfield's lone runway is located directly beneath the final approach to runway 10L at nearby Portland International Airport. The airport lies adjacent to Washington State Route 14 and t ...

Computer Companies Disestablished In 1994
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of computer ...
