Data storage
In an effort to simplify previous implementations of computers on spacecraft, "Mars Climate Orbiter" featured a single computer using an IBM RAD6000 processor utilizing a POWER1 ISA capable of 5, 10 or 20 MHz operation. Data storage was to be maintained on 128 MB of random-access memory (RAM) and 18 MB of flash memory. The flash memory was intended to be used for highly important data, including triplicate copies of the flight system software.
