The RAD750 is a radiation-hardened single board computer manufactured by BAE Systems Electronic Solutions. The successor of the RAD6000, the RAD750 is for use in high radiation environments such as experienced on board satellites and spacecraft. The RAD750 was released in 2001, with the first units launched into space in 2005. The CPU has 10.4 million transistors, nearly a magnitude more than the RAD6000 (which had 1.1 million). It is manufactured using either 250 or 150 nm photolithography and has a die area of 130 mm². It has a core clock of 110 to 200 MHz and can process at 266 MIPS or more. The CPU can include an extended L2 cache to improve performance. The CPU itself can withstand 2,000 to 10,000 gray and temperature ranges between –55 °C and 125 °C and requires 5 watts of power. The standard RAD750 single-board system (CPU and motherboard) can withstand 1,000 gray and temperature ranges between –55 °C and 70 °C and requires 10 watts of power. The RAD750 system has a price that is comparable to the RAD6000 which is US$200,000 per board (per 2002 reference). However customer program requirements and quantities will greatly affect the final unit costs. The RAD750 is based on IBM's PowerPC 750. Its packaging and logic functions are completely compatible with the PowerPC 7xx family.

there is already a curiosity thread.. **well, sort off **

Different filters can be rotated in front of the MastCams, providing images in visible and near-infrared wavelengths. The two nearly identical MastCams will combine to take 3-D stereo images. They can focus on objects as close as about 7 feet from the rover and see details down to roughly a few hundred microns. They will see in “true color,” or approximately what your eyes would see if you were there with Curiosity. The previous rovers, Spirit and Opportunity, could see details about as well as a person would on Mars. But MastCam’s right camera has a 100-mm focal-length lens that provides three times the resolution of previous Mars rover cameras. It can distinguish between a football and a basketball from seven football fields away.

It has color cameras, I suspect they haven't sent any large color images yet due to the low data rate communications (128kbps). I have seen one color image but it's very blurry, they say it has a dust-cover over the lens, which will be removed sometime in the next few weeks.

NASA has taken a colour picture from MAHLI *the camera on the sample taking arm, the arm is shown folded in QuiescentWonder's pic*. The pic is blurry because NASA hasn't taken the lens cover off.
