We have now listed a wealth of Dragon 32 Computer games, including some of the rare cartridge based games, and rare titles such as teh 6809 Assembler/Editor by Q E D Systems on the trading website SellMyRetro.com

Included is a boxed fully working Dragon 32 Home Computer, which in itself is quite rare as the company went out of business shortly after releasing their computers onto the market, with large stocks unsold!

For those of you who have never heard of the Dragon 32 computer - here is the extract from the information on sellmyretro.com

The Dragon 32 Home computer was launched by Dragon Data Limited of Wales in August 1982.
The computer was based on the Motorola MC6809E processor running at 0.89 MHz, together with 32K of RAM, with built in Microsoft BASIC and the ability to load software either from cassette or through the built in cartridge slot.
The processor was an advanced 8-bit CPU design, having, among other things limited 16-bit capabilities. In terms of raw computational power, the Dragon beat most of its contemporary rivals based on the older MOS Technology 6502, and the built-in cartridge slot, with instant loading of games, should have put it head and shoulders above the competition.
Unfortunately, the Dragon 32 was let down by its limited graphis capabilities - with the highest resolution display being 256x192 pixels in 4 colours, which impacted on the attractiveness of the system for games players.
There were striking similarities between the Dragon and the TRS-80 Coco, both being based on a Motorola data sheet design for the MC6883 SAM chip for memory management and peripheral control. The systems were sufficiently similar that a significant fraction of the compiled software produced for one machine would happily run on the other.

Software running via the built-in Microsoft BASIC interpreters also had a high level of compatibility, but only after they were re-tokenized (which could be achieved fairly easily by transferring via cassette tape with appropriate options).
A broad range of peripherals exist for the Dragon 32, and on top of this there are add-ons such as the Dragon's Claw which give the Dragons access to the BBC Micro's large range of accessories (a particularly important factor in the UK home market).

A disk operating system, DragonDOS was supplied as part of the disk controller interface from Dragon Data Ltd.  In addition to the DragonDOS disk operating system, the Dragon 32 is capable of running several others, including FLEX, and even OS-9 which brought UNIX-like multitasking to the platform.
