The 16 chip board is working now (kind of). We are only using 8 chips on one side to hash right now. The Ktest utility that BkkCoins made, can talk to the board, send it test data and read back nonces. The nonces are coming back as "GOOD". The default clock is 64 MHz (it says 128 in the pics below, because BkkCoins says its half frequency). Increasing the clock to 128 also works. Anything more than that, and nonces stop coming back. The board is hashing as well at 64 MHz and 128 MHz, however, its still throwing some errors while hashing. So far it has gone upto 809 MH/s. Its varying a lot right now as the board is throwing hardware errors. Now we will start debugging these errors. However, we believe this is a big feat so far.

In the video below, the red LED is not blinking because I burnt it earlier today. I also show the BTCGuild dashboard, and then refresh it to show the updated number of accepted shares.

I can verify that the desk, k16 board connected to an atx power supply, and PC shown in Terrahash's video are in Amir's office. I sat in front of that desk for a few minutes earlier today. Glad to see you guys are making progress with the 16 chip board!
