I can't seem to lay my hands on a decent electrical description of the Commodore joystick port. Need to confirm that pins 1,2,3,4,& 6 (l/r/u/d/fire) are pulled from high to low when the switch is closed to pin 8 (Ground)
Could someone confirm this?
Thanks Jeff/OBC

Yes. Pins get grounded when you flick the joystick. Pins 5 and 9 can be used for two extra buttons too.

When I did the Nintendo mod, I assigned the B button to the second port fire button. Makes playing Spyhunter nice!
You know there is no reason why joystick manufactures could not have used the POTs lines to create an extra button in the original 80's designs. I'm betting many games would have adopted it.

Yeah, or Breakthru which also used the spacebar for Jump. Why didn't they think of this in the 80's ?? Jeff/OBC

Spyhunter could have used an extra button. So could Gianna Sisters, Ghostbusters, and even games like Ultima. In fact, if you put your mind to it, most games could have made use of the extra button, but some games really needed it.

Naw, kids are spoiled today. The old Commodores and Ataris only needed one FIRE button! I can't believe all the buttons and joysticks they have on the PS2/3 and Xbox. Man, you ONLY need Left, Right, Up, Down, and FIRE!!
