- title: DISK-DRIVE AND JOYSTICK INTERFACE
subtitle: Vaporware !!!
text: |-
This is the only known picture of the vaporware 3.5'' disk-drive and joystick interface for the Alice. They were presented at the Micro-Expo exhibition in Paris in february 1985, along with a modem (not pictured here).
Only the disk-drive and modem are vaporware. The joystick interface was indeed released.

With this add-on, you can use a joystick with the Alice. But you can't use a memory expansion at the same time :-(

The Tandy MC 10 (MC means Micro Color) was designed as an "initiation" computer to compete with the [Timex Sinclair 1000](/museum/timex-sinclair-1000/), the american version of the [Sinclair ZX-81](/museum/sinclair-zx-81/). It was more expensive than the Sinclair machine, but outpassed it in every category. It had sound, color, more memory and even a better keyboard.
In fact, the MC-10 is basically a cut down version of the [Tandy "Coco" computers](/museum/tandy-radio-shack-color-computer/), but didn't have as much success as its big brothers.
It is fully compatible with the first version of the [Matra Alice](/museum/matra-hachette-alice/) (a French computer). Actually both are the same computer (except for the case color, the Alice is red and the Tandy is white).

**Richard Vermeulen** adds:\
The Tandy MC-10 micro color computer was not a commercial success. Tandy did not support this machine. In Basic you could only use 8 color and a graphic resolution of 64x32 dots. However, the MC-10 had much more capabilities: 2 color 256x192 graphics, 4 color 128x192 graphics and the sound-chip had synthesizer posibilities. If all these extra functions were mentioned in the manual, I bet that these machine would have sold much more.
