Dragon 64

The Dragon 64, launched in 83, was exactly the same computer as the Dragon 32, except that it had 64k RAM instead of 32k, an OS9 operating system and a RS232C connector.

The Extended Basic has been modified to provide RS232 I/O calls, to remove the USR bug present in the Dragon 32 ROM and to add calls allowing the additional interpreter to be invoked.
This second interpreter was the same Extended Basic re-compiled to run from a higher memory address and stored in a EPROM. When invoked, the machine was switched into 64k RAM mode and the interpreter copied from EPROM to RAM giving an extra 16K BASIC workspace. (Source : Jon's Dragon Home Page)

The Dragon 64 was sold in various European countries. A slightly modified version was also manufactured and sold in the US by TANO (Technical Associates of New Orleans) from August 1983. They sold the machine under the TANO name for a few months but couldn't compete with the agressive price policy from Commodore, Atari and T.I. All the unsold machine were eventually sold off to a discount store called California Digital.

In 85 Eurohard, a spanish manufacturer, acquired Dragons Data. Then the Dragon 200 replaced the 64 with some minor changes: power-on lights, auto-repeat keyboard... They also also had plans for a 128k Dragon and a MSX Dragon.
