Nasa’s Mars Rover Opportunity Concludes a 15-Year Mission
Was looking through Opportunity's Wikipedia page, and found this cool comparison of the embedded systems used in Mars rovers:<p><a href="https://en.wikipedia.org/wiki/Comparison_of_embedded_computer_systems_on_board_the_Mars_rovers" rel="nofollow">https://en.wikipedia.org/wiki/Comparison_of_embedded_compute...</a><p>That lead me to the RAD6000 page, which was new to me:<p><a href="https://en.wikipedia.org/wiki/IBM_RAD6000" rel="nofollow">https://en.wikipedia.org/wiki/IBM_RAD6000</a><p>"Reported to have a unit cost somewhere between US$200,000 and US$300,000, RAD6000 computers were released for sale in the general commercial market in 1996"<p>Anybody know why the per unit cost is so high? Low yields or is it that much more expensive?
