17. Using your thumb and index finger, carefully rock the J10 ribbon cable back and forth out of the
header as shown right.
18. Using the same method, unplug ribbon cable J11.
19. Unplug the ribbon cable from J13 of the old input board and J3 of the analog board below. The J13
cable will not be reused.
20. Remove the three 6-32 screws (squares) that hold the old board to the 3 spacers.
21. Lift the board out of the chassis moving it away from the rear panel. The piece of copper tape on the
USB connector will peel off of the rear panel, this is ok.
22. Identifying Type A or Type B analog board
There are two types of analog boards. The analog board is the larger bottom board. How the Mark
II Digital Processor board connects to the analog board depends on whether it is an A or a B style of
analog board. The next step is to identify if you have either an A or a B style analog board. Once you
have identified the style, proceed to the A or B installation section to finish the installation.
23. Type A Analog output board
. You’ll note that the Type A analog board has a small black
twelve pin socket (J3 page10) adjacent to the two large power supply capacitors.
24. If your Analog DAC board has this socket you will use the short (3 inch/7.5cm) I2S cable.
