Funny how they call that "low cost" and yet one of those boards will
set you back a few million.

Still, there is the best board around should you like other space
hardware manufacturers wish to put the current best radiation hardened
hardware in your space orientated system.

Has Flash RAM been used in past space probes in any significant way?

Quite successfully on Deep Space 1, as I recall.

Where might one find technical information on the rover such as details
on the computer hardware and software?

Here's a description of the single-board computer at least:

Thanks. I noticed that this board has a PCI bus. Don't tell me they
actually have PCI cards in the Mars rover. Good grief!

Well, what would you have them do, come up with a special bus for
each new space probe?

OK, I won't. But I will tell you it's possible to use a PCI bus
without PCI cards and PCI connectors. For example, many PC
motherboards have on-board devices hooked up to the PCI bus on the
motherboard, avoiding the need for a PCI card and PCI connector. And
I guess they all have the main chipsets hooked up to the PCI bus
without using a card or connector.

OK, but you'd think they'd say something like that.

I heard they got a good deal on some microchannel hardware from IBM.

We are using this board on the BAT instrument on Swift, a Gamma-Ray
Burst satellite we are launching later this year.

Yes, we use the PCI bus to connect to other PCI cards in the card cage
(which is significantly sturdier than the $29 ATX case you pick up Ed's
Computer Shop).
