We're looking for low-power VME manufacturers that use Wind River's VxWorks realtime OS. So far we have come up with Dynatem, who also distributes low-power boards from a german company called "o+r". We're looking for boards that draw around 1 amp. Just as a comparison: Heurikon 68030 cpu 12A Dynatem 68030 cpu 1A (all CMOS) These boards have to reliably run off batteries for many hours. Thanks, Roger Vendor notice: VxWorks support is -not- negotiable. If it won't run with your product, or takes over 1A for a stripped CPU or 2A for a CPU with SCSI and ethernet, please don't bother to call. I don't care if you support OS/9, VRTX, pSOS, etc. We've evaluated them all to death. -- "The question of whether a computer can think is no more interesting than the question of whether a submarine can swim" - Edsgar W.

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.
