Commodore 64 8-bit home computer introduced in January 1982

The Commodore 64, also known as the C64 or the CBM 64, is an 8-bit home computer introduced in January 1982 by Commodore International. It has been listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 10 and 17 million units. Volume production started in early 1982, marketing in August for US$595. Preceded by the Commodore VIC-20 and Commodore PET, the C64 took its name from its 64 kilobytes(65,536 bytes) of RAM. With support for multicolor sprites and a custom chip for waveform generation, the C64 could create superior visuals and audio compared to systems without such custom hardware.

MS-DOS discontinued operating system for x86

MS-DOS is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and some operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS". MS-DOS was the main operating system for IBM PC compatible personal computers during the 1980s and the early 1990s, when it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system.



Thud Ridge is a combat flight simulator that allows the player to pilot a Republic F-105 Thunderchief—a "Thud"—during the Vietnam War. The player must contend with enemy MiGs, SAMs, flak, and a MiG ace known as the Grey Ghost. Thud Ridge presents 10 missions, with the degree of simulation difficulty decided by selecting either Lieutenant, Captain, or Colonel level. The player earns the Bronze Star by completing Missions 1 through 3, the Silver Star and a promotion to Colonel upon completion of Missions 4 through 6, and membership in the Wild Weasel Thud Drivers if the player accomplishes all ten missions.

Republic Aviation 1931-1965 aerospace manufacturer

The Republic Aviation Corporation was an American aircraft manufacturer based in Farmingdale, Long Island, New York. Originally known as the Seversky Aircraft Company, the company was responsible for the design and production of many important military aircraft, including its most famous products: World War II's P-47 Thunderbolt fighter, the F-84 Thunderjet and F-105 Thunderchief jet fighters, as well as the A-10 Thunderbolt II close-support aircraft.

Surface-to-air missile Ground-launched missile designed to attack aerial targets

A surface-to-air missile (SAM), or ground-to-air missile, is a missile designed to be launched from the ground to destroy aircraft or other missiles. It is one type of antiaircraft system; in modern armed forces, missiles have replaced most other forms of dedicated antiaircraft weapons, with anti-aircraft guns pushed into specialized roles.

Anti-aircraft warfare combat operations and doctrine aimed at defeating enemy aerial forces; all measures designed to nullify or reduce the effectiveness of hostile air action

Anti-aircraft warfare or counter-air defence is defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action". They include surface based, subsurface, and air-based weapon systems, associated sensor systems, command and control arrangements and passive measures. It may be used to protect naval, ground, and air forces in any location. However, for most countries the main effort has tended to be 'homeland defence'. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence as are initiatives to adapt air defence to the task of intercepting any projectile in flight.


This game has few commands to learn in order to operate the aircraft. There is no digitized sound, just tinny beeps that indicate actions such as weapons firing. The player handles control of the aircraft by joystick, keyboard, or keypad. The player uses the joystick or keypad to direct the jet’s flight; the keyboard allows the player to input other control commands. The game possesses four basic screens, each offering different aspects of the jet's flight. One screen allows the player to view the aircraft functions screen. The main display presents a real-time view of the player's Thud and the geography of the area over which the plane is flying, as well as weapons and firing information. The plane has an automatic weapons cursor, the shape of which determines the weapon in use. The Engine Function Panel can appear below the real-time graphics display, and presents factors such as the engine and nozzle temperatures and fuel levels on gauges. Other data includes the plane's throttle, an afterburner indicator, the elapsed time of the mission, a radar-lock warning, and a graphic display of the Thud and the weapons remaining aboard. Also available is a screen that shows where SAM installations are located and a map screen. [1]


The game was reviewed in 1989 in Dragon #151 by Hartley, Patricia, and Kirk Lesser in "The Role of Computers" column. The reviewers gave the game 3 out of 5 stars. [1] A 1992 Computer Gaming World survey of wargames with modern settings gave the game two stars out of five. [2]
