- DISCLAIMER:
-
- WIRING OF JOYSTICKS FOR YOUR COMPUTER MAY DAMAGE YOUR COMPUTER IF
- IMPROPERLY DONE. I OR JAEGER SOFTWARE MAKE NO WARRANTY EXPRESSED OR

- RISK. IF YOU ARE NOT COMFORTABLE WITH SOLDER OR PIN WIRING ON ELECTRICAL
- CONNECTORS, REFER THIS ADAPTOR CONSTRUCTION TO SOMEONE PROPERLY QUALIFIED.
-
- Analog Joysticks for use with Amiga Flight Simulators.
-
- Works with:
- Fighter Duel Corsair vs. Zero by Jaeger Software
- Genie Airwarrior by Kesmai
- F-15 Strike Eagle II by Microprose
- (Haven't tested it with others)
-
- If you are one of the fortunate ones to fly a flight simulator that
- supports Analog joysticks, you may have wondered where to get one.
-
- This text file and accompaning Hires Interlaced IFF show the pinouts needed
- to make any late model IBM Analog joystick work with your Amiga.
- You can make an adaptor to use the IBM stick without violating its wiring, voiding
- your warranty, or preventing you from using it on your IBM etc. The list
- of materials:
-
-
- 1 DB9 female joystick extender cable
- 1 DB15 female connector with hood
-
- WHY THIS WIRING:
- According to the Amiga hardware manual and every system guide that comes
- with the Amiga, Pin 5 is for x or horizontal movement and Pin 9 is Y or
- vertical movement. Airwarrior and F-15 Strike Eagle II both reverse these
- pins in the software, so we at Jaeger decided to follow suit to allow air
- warriors with analog sticks to use Fighter Duel. Its not right, but well
- it works as long as the software can compensate for it.
-
- WHY THESE PARTS:
- I have found this the easiest approach. Look for a joystick extender cable
- that has all the pins in it. Ones from Radio Shack work great. Most old
- dead Amiga mouse or joystick cables could be used except they don't have
- all the pins connected in them, especially the ones we need. If you have
- an Amiga 2000 or 2500, make sure you get a extender cable that has the
- usual slim connector end that joysticks have, otherwise it won't fit in the
- connector hold. The reason I don't suggest just buying a female connector
- hood for the DB9 is that I have yet to find one small enough to fit.
-
- WHAT ABOUT RESOLUTION:
- I have heard a lot discussion that IBM sticks aren't good enough for the
- Amiga because the Amiga has higher precision at the port than what IBM
- sticks can generate. Well the Amiga has a larger range on it's
- poteniometers than what IBM sticks can generate, but for flight simulators
- I have found that a slightly reduced sensitivity works just fine. Most
- simulators are so slow in updating the screen that more sensitivity may
- work against you, causing over compensation. In Fighter Duel, where
- everything is based on a realtime 30 frame per second time interval, the
- IBM analog sticks work great. Fighter Duel takes a reading on the stick
- and determines the range by the middle position. This means that the
- better the stick you have, the more range you have.
-
- WHAT STICKS WORK THE BEST:
- Everyone has personal favorites for joysticks. People will fanatically
- defend them like a religion. I prefer the higher end of sticks, ones with
- linear potentiometers, not slide brushes. I'm not big on Yoke type stick
- units, I feel funny flying a fighter with a yoke. I also like sticks with
- suction cups and trigger firebuttons. Here are a couple of ones I own and
- how I rate them.
-
- 1 Quickshot by Bondwell (about $20.00) has slide brushes but still works
- well. Has suction cups and handle trigger button. A little loose in free
- floating mode.
-
- 2 FlightStick by CH industries ( about $40.00 ) nice action, has
- potentiomers, No suction cups, trigger button on handle. Handle is a bit
- small for someone with big hands, works well.
-
- 3 500XJ by Epyx ( about $30.00 ) small tight action. has trigger on base,
- has an unusual one button center trim button, I prefer seperate trim
- controls, don't you?
-
- I hope you enjoy the quick control that an analog stick will give you. By
- the way if you don't feel comfortable making an adaptor like this, give
- Redmond Cable a call with the pinout, they'll make one for you.

- NOTE: The following message was taken off of Genie, I've tried it and
- it works! I've also included a revised picture with this change included.
- I HIGHLY suggest you make this mod! I also tried switch which works fine
- (some games choke on the higher values given with the capasitors installed)
- you can even switch it on while its plugged in! GREAT! Thanks for
- the suggestion Jim Belcher! C&P

- I had a slight problem with my analog stick with Fighter Duel in that just
- the slightest pressure on the stick while in level flight would start my
- plane rolling. So I tested my stick (a Gravis Analog) with the JOYCALC
- program and found that the X and Y ranges for my stick were only 0-36. The
- Amiga is capable of resolving resistance readings of 0-255, so it was
- obvious that my stick was only using a very small part of the Amiga's
- resolving range.
-
- Then I added a .1 uf capacitor between each pot wiper and ground as
- suggested in the AirWarrior Read.me file, and now JOYCALC shows that my
- sticks Y resolution of my stick is now more than doubled.
-
- I no longer have the problem of a super-sensitive stick sending my plane
- into a snap-roll. Also, the stick seems somewhat smoother with less
- overshoot in lining up a bogey in the sights. All in all, a noticeable
- improvement.
-
- I mention all this because some of you guys might have the same problem,
- and with about $ 1.49 in parts you can pretty much solve the problem.:)
