Eventide ARGUS 3000 - Location of Shorting Plug Jack on 5000 and 7000 CPU Boards

4. The rear cover is connected to the CPU board. Slowly pull the rear cover out of the unit housing
until the board is exposed approximately 1-1/2 inches.
5. A ribbon cable connects the solder side of the CPU board to the mother board. Disengage this
connector and slide the CPU board completely out of the unit's housing.
6. On the rear cover there are two pan-head screws, located at either end of the 25 pin D-connector,
which secure the rear cover to the CPU board. Separate the CPU board and rear cover by first
removing these screws.
Remove The Old Jack
7. The shorting plug is mounted near the ROM chips. (Refer to Figure 7.) Heat each solder joint with
the soldering iron until it melts. Remove the solder with the solder wick or solder sucker.
8. When all five holes are free of solder, gently pull the jack free of the board. The pins may have to
be re-heated briefly to loosen them from any residual solder.
