Brellis,
Dawn uses the RAD6000 computer. It is a space qualified, radiation hardened, well behaved, and characterized computer. It is a 25MHZ PowerPC. It is used in almost 200 active spacecraft (look up the RAD6000 in Wiki) The OS is space qualified and called: VxWorks (from Wind River). It is a flavor of UNIX, has a C compiler, libs and is tuned for real time control. I use VxWorks on a kludge at work that tests printed circuit boards. I've always said that given the right transceiver, I could hack into Spirit or Oppy through the backdoor username 'Guest' and password 'Guest' <dream_mode> CODE trying to transmit and receive..... < snap ... crackle....pop....whiz....bang....> ****VxWorks Ver 4.1C Username> GUEST Password> ***** -_-_-_-_ Welcome to MER-A -_-_-_-_-_ -_-_-_-_ Welcome to MER-A -_-_-_-_-_ VxWorks Version 4.1C Kernel: WIND version 2.2 Copyright Wind River Systems Inc, 1990-2003 CPU: PowerPC Memory: 128Mb WDB: Ready ********* enter debug commands or scripts to 'drive' MER-A ********** ********* do not reformat drive ********** > </dream_mode> -------------------- CLA CLL
