What's in a name?
Ailloux is a small river from Auvergne, which ends up feeding the Morge river.
History
Momentum Computers builds embedded systems, including several single board
computers. They used to design VME systems, nowadays they are offering
compact PCI systems.
The Momentum Leopard-V is roughly a Sun Blade 100 system without audio and video devices, and the on-board IDE controller replaced with a more traditional Symbios Logic SCSI controller. In addition, a Tendra Universe VME controller has been added, so that VME devices could be used with the Leopard-V.
The network interface is also not Sun's traditional `HME', but two fast Ethernet DEC 21143. The second one requires a specific transition board to be connected to the board's VME P2 connector, which I don't have. This shows as a warning message during boot, as there is no Ethernet transceiver connected to the controller in the absence of the transition board, making it unusable.

Usage
This board was given to me a few years after the OpenBSD/sparc64 port was
created. It was working out of the box, save for the Tundra chip for which a
device driver was to be written. Despite having the complete Tundra
documentation and a large set of VME boards to test it with, I sadly
never started working on a driver.
Since this machine has a whooping 1GB memory soldered in, in the early months I was using it, I was able to use a memory filesystem for the system build binaries, allowing me to test system-wide changes in a short time. Then the system compiler was upgraded from gcc 2.95 to gcc 3.3, and I had to switch back to using disk storage for builds because the memory filesystem could no longer be large enough.
This machine was used as my main sparc64 build system until late 2014, when I started used `impradine' for that purpose.
