Description

The Dragon MSX-64 is a computer that was intended for the Spanish market by the Eurohard company, but it has never been officially released.

In 1984, Eurohard had bought the Dragon Data company, which had previously released several non-MSX computers. The Dragon MSX-64 was actually build by Radofin Electronics, a British company based in Hong Kong, which also designed the Mattel Aquarius computers. About 500 pieces were delivered, but they were never sold because of Eurohard bankruptcy. Employees were given a Dragon MSX as payment instead of wages.

The function keys are on the left, what's unusual for the MSX computers.

The BIOS/BASIC rom of this machine is divided between two 16kB EPROMS. When you combine them together, it's the same rom that you can find on many European MSX machines with an "international" English keyboard, such as for example the Sony HB-75P.
