As an interesting side note: this microcontroller is what you generally find in keyboards and it costs about 1$. In the 1990's this was one of the few available radiation-hardened microcontrollers (this one actually costs a lot more than 1$, but has the same performance).
I managed to cram a 9 channel 32 bit temperature control system, 7 digitally filtered 32 bit sensor channels and experiment timeline controller into this system, with a staggering 32 kB of memory, where 128 bytes where of the fast kind :-) Just shows what you can do with assembly language programming.
Alice flew without any interaction for months in the MIR. This software had to work perfectly, otherwise the scientist would receive a whole lot of nothing after several months of waiting for the experiment results. Well it did work perfectly and I'm very proud of having written it.
