Dragon Data was a Welsh producer of home computers during the early 1980s.
 These computers, the Dragon 32 and Dragon 64, strongly resembled the Tandy TRS-80 Color Computer ("CoCo")—both followed a standard Motorola datasheet configuration for the three key components (CPU, SAM and VDG).
 The machines came in both 32KB and (later) 64KB versions.
Dragon User was a British magazine for users of the Dragon 32/64 computers published from 1982 by Sunshine Publications.
 Production of the computers themselves had ceased by 1985 but the user community remained sufficiently active to justify the magazine's continuation until 1989.
Cuthbert Goes Walkabout is a 1983 computer game for the Dragon 32/64, TRS-80 CoCo, Commodore 64 and Atari 8-bit family home computers.
 Produced by Microdeal, the game features the hero Cuthbert (a character who also appeared in "Cuthbert Goes Digging", "Cuthbert in Space", "Cuthbert in the Jungle" and "Cuthbert in the Mines").
 The game is based on the Konami arcade game "Amidar".
 The player has to guide Cuthbert around a grid-like level of squares.
 When the player walks all the way around each square it is filled with colour.
 If all the squares are filled, and Cuthbert successfully avoids the monsters and finishes before the time runs out, the player progresses to the next level.
Phantom Slayer is a computer game released by Med Systems in 1982 for the TRS-80 Color Computer and Dragon 32/64.
 Written by Ken Kalish, "Phantom Slayer" is considered by some to be a very early forerunner of the modern first-person shooter genre.
Wintersoft was a British software house based in Enfield, Middlesex and operated by John F. Humphreys and David A. Briskham during the 1980s.
 They produced a number of strategy games for the Dragon 32/64, Oric and ZX Spectrum computers, their titles including the role-playing video games "The Ring of Darkness" and its sequel "Return of the Ring" and also "".
 ("Juxtaposition" was available only for the Dragon machines and another, "Operation Gremlin", was only released for the Oric.
Hareraiser is a computer game, originally released in 1984 in the UK for most home computer platforms.
 It was released in two parts; "Prelude" and "Finale".
 A prize worth £30,000 was on offer if the game could be solved.
 The game was released on Acorn Electron, Amstrad CPC, BBC Micro Model B, Commodore 64, Commodore VIC-20 EX, Dragon 32, MSX, Oric Atmos 48k and Sinclair ZX Spectrum in 1984 at £8.95 for each part.
Kenneth (Ken) Kalish wrote many games for the TRS-80 Color Computer and Dragon 32/64 home computers in the early 1980s, including:-
TK82C was a Sinclair ZX81 clone made by Microdigital Eletrônica Ltda.
, a computer company located in Brazil.
The Dragon 32 and Dragon 64 are home computers that were built in the 1980s.
 The Dragons are very similar to the TRS-80 Color Computer, and were produced for the European market by Dragon Data, Ltd., in Port Talbot, Wales, and for the US market by Tano of New Orleans, Louisiana.
 The model numbers reflect the primary difference between the two machines, which have 32 and 64 kilobytes of RAM, respectively.
Bonka is a clone of the arcade game "Space Panic" released for the Dragon 32 and Commodore 64 in 1983.
