Am I correct in > assuming that they'd also work with the trackball?) The Atari (and presumably any other compatible) Trakball controllers (there were at least 2 different Atari trakballs) do _not_ work exactly like an ST mouse. I tried the old GOE demo disk with an ST mouse and it worked as it was supposed to. But with my (CX22 I think is the model number) trakball, the cursor moves to the upper left corner of the screen and is stuck there (in trakball mode), or moves, "flakily," 90 (or is it 270?) degrees from the intended direction (in joystick mode). As far as Diamond goes, I can't say. (At the last meeting of my users' group, we saw Diamond respond to an ST mouse, but we couldn't get it to do anything - we had no manual - and I didn't have my trakball with me anyway.) However, I have (at home, not here) some instructions on modifying an Atari trakball (at least for the type I have, I may have saved the other instructns.) to act like an ST mouse. I got them from DELPHI, which means they must be all over the place since (except for stuff from ANALOG magazine) DELPHI is about the last place to get anything (if it gets there at all). If you can't find these instructions on whatever BBSs and/or pay services you have access to, I will dig them out and (especially if I have them in a disk file) and mail or post them (depending on the level of interest here). Disclaimer: I have not made any modification to my trakball. It is often all too easy to destroy a device while trying to modify it (although this is much more likely with the computer itself, I believe). Caveat Hackor.
