Could be a test model of the Envoy 100 someone at Silicone Graphics lent them. It certainly appears to be branded by Motorola. They had $875,000 worth of Silicone Graphics hardware, $350,000 from Apple, and $500,000 in additional hardware and software to equip and run the control room. You have a 150 pictured, but from what I read there should not be that significant of a difference in the base of the Envoy between the 150 and 100. The production model appears to still have the two slots there, but not with the cutout (which likely broke on the test models).
