We have been running a Dynatem DCPU-30 on the Uranus mobile robot for over a
year, and it works great. All memory is battery backed, which is very
convenient. We made a minor mod to the board so the timers can generate
on-board interrupts (across the daughter card connector to the daughter card
vector), since the fastest rate through the RTC wasn't fast enough for us.

VxWorks support for the board has just become available, and I issued a PO for
it this afternoon. Note that VxWorks will support the Dynatem DLAN ethernet
controller (3U size card, 1A current draw), but not the XLAN daughter card.
