At the time when the Amstrad [GX 4000](/museum/amstrad-gx-4000/) game console and the [CPC+ computers](/museum/amstrad-464-6128-plus/) were launched, Amstrad had designed this metallic box to be used by dealers as a demonstration model. It was mainly used in the UK by Dixons chain dealers. Of course, very few models were produced.
|
|
|
|
When opening the front side of the sturdy aluminium case, one finds a metal plate covering the main board, actually a CPC 464+ motherboard, and a daughterboard holding 13 cartridge connectors. The first connector always holds a custom main cartridge which controls the CSD system. Twelve connectors remain free for standard game cartridges. The two boards are connected together through the cartridge and parallel ports of the motherboard.
|
|
|
|
When the cartridges are inserted and the front cover is closed, a superb Welcome picture appears on the screen with a 4096-colour wave background. It is then possible to select a cartridge and run a game, or let the machine run all the games successively. A timer then allows the user to select how long each game will be played.

Thanks to **Charles da Silva** and his [site](http://amstrad.cpc.free.fr/) for information and pictures.

As Roland Perry told me, Amstrad used not only CPC 464+ motherboards but also GX-4000 PCBs. In fact, they used whatever they could find. Another interesting thing is that the CSD was delivered to dealers in a nice wooden stand, like the ones we can find today for the Sony PS2 or Microsoft Xbox.
