HAWK-800 Constructions and Installations Instructions –
●
Once you have carefully inserted the socket, check the back of the board to make sure that all 16 pins went
through their respective holes. Also make sure that none of the pin sockets have pushed out of the socket. Do not
start soldering until you have confirmed that all 16 pins went through the holes fully and correctly.
●
Ensure that the socket is firmly seated then solder two diagonally opposite pins. Double check that the socket is
seated completely and then solder all of the rest of the pins.
Step 9A – Removing the IC22 EPROM socket
If you are installing the HAWK kit into a Poly-800 MK2 then go to step 9B. If you are installing the HAWK kit into a original
Poly-800 or an EX-800 then the next step is to remove the IC22 EPROM socket. This is necessary because the existing
socket uses very high side walls which make it impossible for a DIP header cable to securely plug in .
●
Identify the IC22 EPROM socket.
●
Remove the EPROM and store it so that you can reuse it if needed.
●
Remove the socket. It is OK to damage or even destroy the socket since we do not need to reuse the socket. But
exercise great care so that you do not damage the board itself or any of the tracks or through holes.
●
Ensure that all 28 pin holes are cleared of solder so that you can proceed onto the next step.
Step 9B – Remove main board connectors CN13A and CN14A
If you are installing the HAWK kit into a Poly-800 MK2 then the next step is to remove the two connectors that join the
main board to the effects board. These two connectors are soldered into place on the main board where IC22 was found in
the original and EX-800 versions.
●
The connectors CN13A and CN14A must be removed from the MK2 main board (KLM-1032).
●
WARNING: Be careful that you do not damage the CN13A or CN14A connectors because they both must be
reused on the HAWK-800 board. Take care to remove the connectors without melting the plastic or damaging the
pins. Take extra care to ensure that you do not damage any of the copper tracks on the printed circuit board.
●
Once you have removed the connectors double check that all pins are present. Replace any pins that might have
separated from the connector.
●
Set the CN13A and CN14A connectors aside where you won't lose them.
●
Now make sure that all 28 holes associated with the two connectors on the main board are completely clean of all
solder since we need to install a 28 pin socket in this location.
Step 10 – Installing the 28 pin DIP Socket
Now install a 28 pin DIP socket where the IC22 EPROM socket was just removed (for the MK2 where CN13A and CN14A
were located and just removed). Use the picture below to determine the orientation of the socket. At one end of the
socket is a notch that is used as a pointer to determine where pin 1 of each chip should be. You need to make sure that you
get the orientation correct.
●
Double check to make sure that all 28 holes are completely clear of solder so that the socket can be inserted
without bending or rolling over any of the 28 pins.
●
Carefully insert a 28 pin DIP socket into the location. Ensure that the notch of the socket matches the picture
shown below.
●
Once you have carefully inserted the socket, check the back of the board to make sure that all 28 pins went
through their respective holes. Also make sure that none of the pin sockets have pushed out of the socket. Do not
start soldering until you have confirmed that all 28 pins went through the holes correctly and that none of the
pins have slightly pushed out of the socket itself.
