Gorf Joysticks.

(1/3) > >>

SavannahLion:
Got a hold of a couple of Gorf sticks in need of rebuilding. It seems the previous owner(s) might have done a half-hearted attempt on at least one of them, but it appears to be salvageable. Some new screws, springs, soldering, etc. One of the control boards has a ~1" crack on the corner near the IC. It looks like the crack runs through the ground plane and I can jumper the cracked trace. I won't know until I test it.

I managed to locate the pinout and it looks pretty basic, U/D/L/R/Ground/+5v. And reading the datasheet on the IC, it seems pretty straight forward. However, I've never actually given much thought to the signal levels/types on the control boards like the Ipac or KeyWiz.

Is it possible to easily interface the joystick control board with something like the Ipac or Keywiz? Or is there some kind of painful adapter circuitry involved? I've seen quite a few projects mention using Gorf or similar joysticks, but they all seem to use the Tron or similarly switched base.

The other Q is, are the parts from Happs Heavy Duty 8-Way Trigger Joystick compatible with the Gorf joystick? Specifically the rubber grommit 96-4550-01. Both of mine have some cracking so I don't know if they're any good.

Edit: Clarified question

MinerAl:
I know the handle of a Gorf stick is the same as the Happ HD, and I believe the structure of the base is the same as well. 

That said, the only Gorf sticks I have are from the cocktail and are switches.

If you post close up pics of the base (and later maybe add them to the Tron sticks page on the Wiki) I may be able to help more.

Sure, I'll give it a shot. You think the control board can constitute its own page?

MinerAl:
Why not?  If it will help somebody later on, definitely!

SavannahLion:
Alright, I'll give it a shot. I figured out the schematic and the IC on there. Some weirdness here and there but I think I understand why Bally built a board like that.  I'll need some other parts though, namely an Ipac* or *Wiz to play with, the rest I'll try to scrounge tomorrow from HSC or something. Maybe I'll get really lucky and find a 5v DC wallwart there so I won't have to set up the PC PSU.
