Multi Emulator Super System

Multi Emulator Super System (MESS) is an emulator for many game consoles and computer systems, based on the MAME core and now a part of MAME. MESS emulates portable and console gaming systems, computer platforms, and calculators. The project strives for accuracy and portability and therefore is not always the fastest emulator for any one particular system. However, its accuracy makes it useful for homebrew game development.

As of April 2015 MESS supported 994 unique systems with 2,106 total system variations. However, not all of the systems in MESS are functional; some are marked as non-working or are in development. MESS was first released in 1998 and has been under constant development since.

MAME and MESS were once separate applications, but were later developed and released together from a single source repository. MAMEDEV member David Haywood maintained and distributed UME (Universal Machine Emulator) which combined much of the functionality of MAME and MESS in a single application. More recently, on May 27, 2015, MESS was formally integrated with MAME and became a part of MAME.

Atex (software), a software company.

Atex (software)

Atex is a company specializing in the development of advertising, editorial and web content management systems. The company was established in Massachusetts in 1973 and grew to become a worldwide hardware and software supplier to the publishing industry. It participated in much of the change in the print industry involving the move from hot-metal through photo and then laser typesetting, culminating in computer to plate (CTP). The company expanded to include web publishing as an integral part of its product line.

The company claims to have over $1 billion USD worth of software installed worldwide, and claims more than 1000 customers in 55 countries. The company is based in Reading, Berkshire, UK and backed by Norwegian investment company Kistefos. It employs over 600 people globally.

History

1970s

Atex was founded in Massachusetts in 1973 by Douglas Drane and Charles and Richard Ying, graduates of MIT, who had an idea for a new type of electronic composition system. By 1974 they had created a prototype video display terminal, encased in a cardboard whiskey carton.

ATEX directive

The ATEX directive consists of two EU directives describing what equipment and work environment is allowed in an environment with an explosive atmosphere. ATEX derives its name from the French title of the 94/9/EC directive: Appareils destinés à être utilisés en ATmosphères EXplosibles.

Directives

As of July 2003, organizations in EU must follow the directives to protect employees from explosion risk in areas with an explosive atmosphere.

There are two ATEX directives (one for the manufacturer and one for the user of the equipment):

the ATEX 95 equipment directive 94/9/EC, Equipment and protective systems intended for use in potentially explosive atmospheres;

the ATEX 137 workplace directive 99/92/EC, Minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres.

The ATEX 94/9/EU that is dedicated to the manufacturer has changed. Still applicable up to 19 April 2016 the ATEX 94/9/EC will be removed and replaced by a new directive.
