-Current status: All sockets are installed. Almost all resistors are installed. VGA, keyboard and mouse adapters are installed. I am waiting for the remaining parts to arrive to finish up the soldering work. I also need to fix the reversed diodes and the 2.5K resistor. I will then run voltage check across the board to ensure no solder bridges or shorts, burn the firmware and start the process to bring it up.+Partial success. I was finally able to solder the CPLD onto the adapter, but the Ethernet chip is bit trickier.

 +I have redesigned the adapter boards to make them easier to solder by using longer pads under the chip as shown below. This is the PQFP-100 board. The TQFP-128 has been similarly redone. These adapters will be included with the final release boards if they are still needed .  (And yes, the pin number for the start of the fourth port should read 81, not 71.  I made a little mistake with the numbering.)

 +Current status: All sockets are installed. Almost all resistors are installed. VGA, keyboard and mouse adapters are installed. I am soldering in the last few items, then I will run a voltage check across the board to ensure no solder bridges or shorts, burn the firmware and start the process to bring it up.
