i have modified the assimilation mac trackball to work with thw amiga this has two buttons and they are wired together to work on the mac. basically you have to isolate thr right button by cutting two traces connect it back through the circuit and bring it out on a separate line. there are insufficient wires in the cable provided. a patch connector also has to be made. i posted mac and amiga pinouts previously. the only thing that threw me is that the right button has to be connected to mouse 3 on the amiga. if there is any interst i will try to post a summary of the mod. i think if you take the trackball apart and stare at it you will see what has to be done. it is nice not having to save space on a desk for the mouse bob flocchini ucdavis!deneb!flocchini *** REPLACE THIS LINE WITH YOUR MESSAGE ***

:r mac_mouse the pinouts for the mac mouse are i believe as follows 1 GND 2 +5V 3 GND 4 X2 left right motion 5 X1 int lr 6 NC 7 Button 8 Y2 up down motion 9 Y1 int up-down the pinouts for the amiga are in the manual. bob flocchini ucdavis!deneb!flocchini *** REPLACE THIS LINE WITH YOUR MESSAGE ***

i have just purchased an atari track ball (for $4.99 new!). I'd like to use it with my amiga as a mouse replacement, but just plugging it in to the mouse port doesn't work. Really I have two problems. 1) it doesn't move the cursor, 2) neither fire button seems to select or to pull down menus. Is there software to make trackballs work like mice? To make joysticks work like mice (the trackball can emulate a joystick with the flip of a switch)? Is there software other than MarbleMadness which supports a trackball? Is there a way to hack the hardware of the trackball to make it act like a mouse? Thanks for your email replies. I will summarize and post if the replies warrant it. -- -Dale Larson (dlarson@blake.u.washington.edu)

Let me preface this message by stating that instructions have posted many times on how to hack an Atari Trakball, hopefully some kind soul will email(I will if I can dig it up). Now for the bad news - I also obtained an Atari Trakball for $4 or so while on vacation and when I excitedly disassmebled mine and found to my chagrin that the posted instructions must have been referring to a different model. If this is the case email me and I'll try to re-create my steps. It turns out that Atari has a lot of logic inside to convert mouse(trakball) type quadrature signals into either joystick position info or some other weird encoded form, depending on the posiion of the switch on the back panel labelled JS/TB. The unit black and quite massive with a ball almost the size of a billiards ball. The only markings other than ATARI TRAK-BALL is "KM-483 8" on a paper label stuck on the underside. The two fire buttons are wired together, but I was easily able to bring both out with a cut and jumper. As a note of encouragement, I note that shoot'em ups such as Hybris and Battle Squadron greatly benefit from this nifty appliance!

Thanks to everyone who replied. Unfortunately, the Atari 2600 trackball which I purchased is a board rev. different than that for which instructions have been posted. Someone else has successfully hacked it and is going to try to generate instructions for me (this trackball has the JS/TB switch and two buttons wired together, but no socketed ic's and no testpoints and different numbered ic's than some of the instructions require). If I successfully convert this one, I'll post. If anyone wants old instructions, I'll email since they've been posted several times before. -- -Dale Larson (dlarson@blake.u.washington.edu)

The main problem is how to specify the cuts and jumps on the network(picture's worth a thousand words and all that). I'll try to get it together and post in the next several days. I'm afraid that between my taking care of my two little girls at home, and some girls named Denise and Agnus here at camp commodore, the entire matter had slipped my mind. In the mean time I won't tease you with testimonials as to its effectiveness in games like Hybris and Battle Squadron which benefit greatly from analog control.

With the renewed interest in trackball hacking, I should point out that
there's a collection of hacks available for ftp from "new xanth" (is it
ever going to get a "real" name?).

If you don't have ftp access, e-mail me, and I'll send you a copy of it.
The file includes my Wico trackball hack and 3-4 Atari trackball hacks
by others.
