The Dragon 32/64 Computers
The Dragon is an 8-bit personal computer based upon the Motorola MC6809E microprocessor. Made in Wales by Dragon Data Ltd., two variants were sold in the UK: the Dragon 32 (basic version, 32K RAM) and the Dragon 64 (64K RAM, serial port, other very minor differences). The on-board ROM contains a version of Microsoft Extended Colour BASIC, but more advanced operating systems like OS-9 and FLEX are available.
An NTSC version of the Dragon 64 was released in the USA as the Tano Dragon, and Eurohard repackaged it in Spain as the Dragon 200.
