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

• TRS-80 Color Computer
• Dragon 32/64
• Laser 200
• TRS-80 MC-10/Matra Alice
• NEC PC-6000 series
• Acorn Atom
• APF Imagination Machine

The VDG is a relatively simple display generator compared to other display chips of the time. It is capable of displaying alphanumeric text, semigraphics and raster graphics contained within a roughly square display matrix 256 pixels wide by 192 lines high.

The ROM includes a 5 x 7 pixel font, compatible with 6-bit ASCII. Effects such as inverse video or colored text (green on dark green; orange on dark orange) are possible.

The MC6847 is capable of displaying nine colors:

• black
• green
• yellow
• blue
• red
• buff (almost-but-not-quite white)
• cyan
• magenta
• and orange

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.
