Assumption: You are talking about the right joystick port. According to my schematic (yours may differ slightly)... +5V _ 74LS157 | ______ > RP200 | | Connector < | U202 |----- _C1 --------- +-------+ | | | pin 4 ----+---------| FB204 |------+----------|6 4|----- M1V | +-------+ | 7|----- M1H --- | 9|----- M0V --- C248 | 12|----- M0H | | 13|---+ | | | | ----- | | ----- --- +------+ --- - - Notes: FB204 is a ferrite bead, and should have no physical connection with the circuit. Most likely culprits are U202 or C248 (in that order). Hope this helps. -larry -- Gallium Arsenide is the technology of the future; always has been, always will be. +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+

It seems that my 2000 has suffered an injury. A few weeks ago I was flying F18 when my plane began to roll to the right as if I was pushing the joystick to the right (even though I wasn't). Even with an uncontrollable F18 and 3 Migs in my tail I was still able to kill 2 of the Migs with those wonderful Sparrows and bail out. I disassembled the joystick and found that one of the switches had failed and possibly shorted, so I tossed it aside and haven't played a game since (I mostly do animations and painting on my Amy). Just the other day I cranked up F18 for another flight when whadda you know? The plane iss still rolling! Even with NO joystick or keyboard plugged in! I tried a few other games that use joy2 and they all exhibit this behavior. It seems like something has gone amiss inside the Amiga that's making it think that joystick 2 is always pushed to the right. What could cause this? I think I fried something.. and the *REALLY* weird thing is that the joystick that broke on me was wireless! It's a Camerica Infrared Freedom Stick. Any takers on this?
