The Multi-cart by Rolo was designed to to hold a variety of Dragon 32-64/CoCo 2 rom cartridge based programs, which are running directly from the eprom at address range $c000 to $ff00.

The cart holds up to 64 8k-roms. It can play roms with a size of 1k to 16k. You simply select a memory slot from 00 to 63, press RESET on your Dragon, and the program launches.

This enables you, to use your Dragon simply without further hardware setup: no cables, no drives, no extra PSUs, no controller-carts.

The Dragon/CoCo 2 Multi-cartridge now can also be used for other systems.

Currently there are three Extension Cartridges (adapters) available:

• VECTREX.
• Odyssey 2/PHILIPS G7000/G7200/G7400.
• INTERTON ELECTRONIC VC 4000.

A compilation of rom-files for all four systems can be burned on a single eprom (27C4001), adding versatility to the device.

from Wikipedia:

The Dragon 32 and Dragon 64 are home computers that were built in the 1980s. The Dragons are very similar to the TRS-80 Color Computer (CoCo), and were produced for the European market by Dragon Data, Ltd., in Port Talbot, Wales, and for the US market by Tano of New Orleans, Louisiana. The model numbers reflect the primary difference between the two machines, which have 32 and 64 kilobytes of RAM, respectively.

In the early 1980s, the British home computer market was booming. New machines were released almost monthly. In August 1982, Dragon Data joined the fray with the Dragon 32; the Dragon 64 followed a year later. The computers sold quite well initially and attracted the interest of several independent software developers, most notably Microdeal. A magazine, Dragon User also began publication shortly after the machine’s launch.

In the private home computer market, where games were a significant driver, the Dragon suffered due to its graphical capabilities, which were inferior to contemporary machines such as the Sinclair ZX Spectrum and BBC Micro.

The Dragon was also unable to display lower-case letters easily. Some more sophisticated applications would synthesise them using high-resolution graphics modes (in the same way that user-defined characters would be designed for purely graphical applications such as games). Simpler programs just managed without lower case. This effectively locked it out of the then-blooming educational market.

As a result of these limitations, the Dragon was not a commercial success, and Dragon Data collapsed in June 1984.
