Since the sticks are purpose built for the 5200, they're using a resistor wired to the switches themselves since they are two state switches, I'm assuming at least one (resistor) for each axis. If you look at the pic the micro-switches on each axis are wired differently from one another, one wired normally open and other wired normally closed. Each axis has three states of resistance based on the state of the switches: 0k, 250k (centered), open circuit (max resistance). When making an external adapter all your switches are normally open so you can't wire anything to normally closed switch, thus its more complicated.
What's really strange (to me at least) is that there doesn't seem to be any circuitry inside the stick other than the wires coming from the switches to the cable. I guess I assumed that something else would be required to hook up digital switches to the 5200, like Prodos had said. It doesn't look there could be anything in the cable either.
Whoa, it's surprising to see switches like those in controllers that old. They're also in arcade joysticks by Pelican and Red Octane, and they tend to be a lot more responsive than the crummy springs used in most early 1980's controllers.
Have you tried using these on Ms. Pac-Man, Vanguard or Qix? I bet you'll have trouble since imo the sticks use an open circuit for infinite resistance.
That makes a certain amount of sense.
Maybe you can help me figure out something else while you are at it, and I'm sure it's related to what you just said. I can't use the trakball with this joystick which really sucks as the would be a perfect combination. Do the Masterplay or Redemption allow you use the trakball as the keypad?
As for Ms. Pac Man, it seems to work as well as I would expect any 8-way stick on a 4 directional game. You just have to make sure the stick on the analog controller is centered. Obviously, any games that use the analog aspect of the stock controller doesn't work with the Comp Pro.
Really, to be honest, I have no problem with the original sticks
it's the FIRE buttons I hate with a passion! I need to at least get the parts to refurb a couple of my controllers. Out of the 5 stock controllers I have, only one has working fire buttons, and they are flaky at best. Same with the Trakball, which could
have been the best controller of all time except for the awful fire buttons. One of these days, I'm going to get some Happs arcade buttons and wire them in.
