We continue to consume large amounts of test time at Vitesse. At present, 11591, we have functional devices for all seven custom chip types required by the OBP80 board. We have sufficient quantity of devices on hand to build several engineering models. We continue to test the SECS hardware and software since it was received from Analytyx last month. Figure 3 shows the portable SECS tester installed in the laboratory, along with the PC, power supplies, and test equipment. The PC software is responsible for controlling the printed wiring board in the SECS tester. The first prototype OBP80 CPU bare board has been received from AITMicrowire. This board geometry looks good, but the solder tinning of the pad areas is not as uniform as we would like. It appears good enough to construct the first processor with, and is due to be shipped to SMTEK for component assembly by 112591.
