How to emulate Raspberry Pi computer

How much money we would you have to spent to assemble a simple x86 PC (Intel/AMD compatible PC)? With the prices on the market it sounds almost impossible to buy all the necessary elements under a 100$ budget. But if Intel binary compatibility is not your requirements you can try a cheapest ARM based computer called Raspberry Pi.

What is Raspberry Pi

For about only 35$ you can buy a complete ARM compatible PC. 

The Raspberry Pi (short: RPi or RasPi) is an ultra-low-cost ($25-$35) credit-card sized Linux computer.

The Raspberry Pi measures 85.60mm x 56mm x 21mm, with a little overlap for the SD card. It weighs 45g. 

Graphics capabilities are roughly equivalent to Xbox 1 level of performance.

Overall real world performance is something like an old 300MHz Pentium 2, with kind of better graphics.

The device is powered by 5v micro USB.

Raspberry Pi emulator

You can use qemu emulator that works on Linux and Windows to run and test almost any Raspberry compatible distribution. The emulator will take care of abstracting the necessary ARM underlying hardware when the system is turned on. For detailed instruction we can use Google or follow one of these links:
