Omnibyte Taurus
---------------
The Omnibyte board has a 68040 and a 68030 on the same board. VSB is
added by an optional mezzanine board. VME64 is optional, but
supposedly available. VxWorks BSP is supposedly available. The price
of these boards is quite low. We've had two of these boards on order
since about February and we haven't seen them yet. We're about to give
up on Omnibyte!


Creative Electronic Systems FIC 8234
------------------------------------
Just got a CES FIC 8234 board in house today. This board has two
68040's on the same board along with VME64, VSB, SCSI, Ethernet, 8 MB
or more of DRAM. This board is setup with lots of support for
multi-processing, not just between the dual '040s, but between cards
across either VME or VSB. The board does the best job I've seen of
supporting the bus snooping modes of the '040. It also has lots of
interprocessor mailbox interrupts and interprocessor FIFOs. 

CES is a Swiss company. They are represented in the US by a company in
Scottsdale, AZ called Compware who is working on, and has delivered to
us, a VxWorks BSP. Both '040s run VxWorks. One '040 talks to the
Ethernet interface and the other '040 is networked to the first via
the VxWorks backpanel network driver, except in this case, the traffic
doesn't go across the backpanel, just through the shared local RAM.

Compware can be reached at 602 998-8650.


Motorola MVME-166
-----------------
This board is a derivative of the MVME-167. The main difference is
that the 166 has VSB whereas the 167 doesn't. The 166 supports VME64,
has VSB, has SCSI, and ethernet. The 166 has a single 33Mhz 68040 CPU.
The 166 isn't quite shipping yet due to the fact that the VSB ASIC is
being turned. Motorola has shipped a bunch of MVME-168 cards to us in
the interim. The 168 is a 166 with the VSB ASIC missing. Motorola is
going to take the 168s back and replace them with 166s in about 6
weeks. The 166/7/8 family all use the same VxWorks BSP which is
supported by Wind River Systems.

We've also evaluated the Force CPU40, Tadpole TP41, and Radstone
PME68-41, but none of these support VME64. Didn't really like any of
these three anyway.
