You can use a 74hc14 hex inverter chip to do this. Connect a 100k resistor between pins 1 and 2. Connect a capacitor from pin 1 to ground. Pin 2 will give you a square wave. It's best to buffer it with another inverter though. So connect pin 2 to pin 3. The buffered output would be on pin 4. Connect that to pin 6 of the joystick port. You can power the circuit from the port as well. The 2600 has VCC (+5V) going out on pin 7 of the joystick ports. Pin 8 is ground. Pin 6 is the joystick fire button input.
The firing rate is proportional to the product of R and C. Try 1uF and 100k Ohm values to start. I don't have a 74HC14 handy, so I'm completely guessing the values for R and C. This should be slow enough for you to see the result. Reduce the values to speed it up, increase them to slow it down.
ummmmmmmmmmmmmmmmmm... schematic?

If someone could give me the address or directions, I'm in the neighborhood.
can't you just use your GPS? "GPS PHONE HOME!"

What, no woodgrain joystick to go with the console?
it goes with the golden console

AC adapter
If it's 4-port, I'll trade you for the Atari 400 ac adapter.
what? it's just the adapter, says "atari use only with model CX5200)

not raining, but It looks ready to pour, so I won't take any chances.

Great idea but I don't think I like it with a LED on the fire button.
:!:
True, the LED should be underneath it and the button be a vacuum formed transparent plastic.
Then you'll like v2

Hold the jack to your tongue for a sec. 9 volts DC ain't gonna kill you.
Hey, you stole mine! Try all of the channels.

did I just answer my own Question?

is the joystick designed so that when the buttons are pushed, a ground signal is sent to the appropriate pin? this is my theory, but I need confirmation for my project. In the schematic, what I thought was when the buttons were pushed, the positive signal went to ground. so I put in the diodes to prevent other buttons from activating multiple LED's. but if this was the architecture, there would be no practical way that I can think of to read the pins, and if the first design described is the one used (which I am betting on) this schematic would block out the signals making the joystick useless. The only fix I can think of (correct me if I'm wrong) is to remove the diodes, change the transistors from NPN to PNP, and place them on the opposite side of the switch.LED__s_vX.bmp

OH %@*&! JUST SPLIT THE CASING DRILLING HOLE FOR THE RAPID-FIRE TOGGLE! :x (it's not noticable tho, just needs some glue
atari 5200 adapter for trade.

all I want is the adapter pleez!
