The Dragon 32 was introduced in 1982. The computer was very similar to the TRS-80 Color Computer (the CoCo 1). The computer was produced by Dragon Data in Wales, by Eurohard in Spain and by Tano in Louisiana USA. The Dragon 32 came with 32KByte of memory and was upgradable to 64KByte. The differences with the TRS-80 Color Computer were small enough that a significant amount of software written for the CoCo could run on both. BASIC tokens are different, but if a program was re-tokenized, the software would typically run without too many changes. In fact the Dragon BASIC version is almost identical to Tandy's Color Computer Extended Basic. There are only a few tweaks in order to access certain Dragon features.

It is even possible to permanently convert a Color Computer into a Dragon by swapping the Orinal Color Computer ROM and rewiring the keyboard cable. The dragon also has a centronics parallel printer port, that was not present on the TRS-80 Color Computer.

The Dragon's main display mode is a black on green quarter-tile block mode. There are also five high-resolution modes, named PMODE 0 to 4. The highest resolution possible is 256x192 in monochrome. The lower resolutions allow for more color.

The dragon originally started out life as a 16K prototype code named "Pippin" (hand built by PA Technology in Cambridge in October 1981) as part of project SAM and has started production when Sinclair launched their 48K Spectrum Computer.

The prototype was almost identical in design to the Dragon 32 that became the launch machine. What is not commonly known is that the 1st 10,000 Dragons were manufactured as 16K machines. The decision to move to 32K came too late in the process to change the production run and these machines had to have a 16K "piggy-back" RAM board fitted at the factory to make the Dragon 32.

The MC6847 is a video display generator (VDG) first introduced by Motorola and used in the following machines (this is not a full list):

The Motorola 6809 is an 8-bit microprocessor with some 16-bit features. It was designed by Motorola's Terry Ritter and Joel Boney and introduced in 1978. Although source compatible with the earlier Motorola 6800, the 6809 offered significant improvements over it and 8-bit contemporaries like the MOS Technology 6502, including a hardware multiplication instruction, 16-bit arithmetic, system and user stack registers allowing re-entrant code, improved interrupts, position-independent code and an orthogonal instruction set architecture with a comprehensive set of addressing modes.
