Philae is controlled by 2 RTX2010 CPUs (hot red), further 8 control the Experiments. 13 CPUs (10* RTX2010, 1* ADSP-21020, 2* 80C3x) in total. © https://twitter.

  > 80C3x An 8051-family microcontroller, the CPU architecture that's found almost everywhere - including space. I wonder if they're running Forth too, as this old discussion I found also mentions 80C32 and RTX2010 together with Forth: https://groups.google.com/d/topic/comp.lang.forth/7PK44n68I_4 https://groups.google.com/d/topic/comp.lang.forth/7PK44n68I_...

    The 8052AH-BASIC is better known because of a Byte Magazine article, but there was also a commercially available 8051 variant that was mask programmed with a built in Forth interpreter. I've never seen one.

  For future archaeologists wondering why everyone is talking about Philae, the title of this thread used to be to the effect of "The rad-hard CPU used in Philae".
