how to adapt your 2600 controller for about a dollar

it may sound like a sensational headline but if you have some skill and fortitude it can be done

 

parts list

 

some thin wire (i just used some old ac adapter wire) so free

 

momentary push button (for start)

 

db-9 male connector less than 50 cents most places they can be found

 

db-15 female connector less than 50 cents

 

two 240k resistors about 10 cents each

 

soldering iron (if you dont have one you probably shouldn't attempt this)

 

ohm meter for testing your work

ok to make it less confusing i'll break it into stages

 

left and up directions

 

down and right directions

 

buttons

 

start button

 

adapter harness

 

since you will be using the original cable and plug after modification you should mark the plug end with some tape (not for 2600)

 

 

i recommend using a joystick that has 2 fire buttons you can isolate them and use them as b1 and b2

if not drill a hole and use a momentary pushbutton the resistors will be inside the joystick carcas not in the adapter harness

 

you will also need to cut off the metal housing for the 15 pin plug and fuse the 2 plastic parts together with the soldering iron (careful because freshly cut metal is often sharp)

 

here is my horrible complex confusing diagram but if you just take them one by one you can do it

 

after opening your joystick you will want to isolate the common ground from the buttons via circuit board cuts or with a wico or suncom stick cutting wires (the black one is often the ground what you want is the top and left common to still be connected and

 

the right and bottom to remain connected and have the buttons common also be tied to the right and bottom

 

any questions?
