Check your cable again. If 1 (Vcc), 8 (GND) weren't connected, your controller wouldn't work. (There is no 9, it's an 8-pin connector, this is probably shell ground).
There's a schematic on the wiki
The following reply will clearly indicate why Gamesx.com never became popular:
You've got a diagram showing a chip, the 74163, which has four outputs labeled Q1, Q2, Q3 and Q4. Your autofire circuit uses Q2 and Q3, and triggers on every 4th and 8th pulse. You might assume that Q1 and Q4 would fire on every 2nd and 16th pulse, or you might hunt for a datasheet for this insanely common, generic part that's been in production for what must certainly be a thousand years, and verify this yourself.
Or you could ask someone else to work it out for you.
Gamesx was never intended to be a place where solutions were found, only the raw data so you could figure things out yourself. I don't even want to answer the question, I'd rather spend 10 minutes telling you how to work it out yourself. And, in fact, I have.
