I have a little problem with my 1040ST which I just bought used: the mouse doesn't work in the horizontal direction. It's very strange, but no matter which way I move it, the cursor moves to the right. The vertical axis is OK. If I move the mouse really fast to the left, it may move in that direction, though. Anyone, have any ideas about what may be wrong? I would especially appreciate anyone in the Ithaca area who can give me a call, or email. Thanks in advance :-).

The vertical axis is OK. If I move the mouse Sounds like the rollers need cleaning. Just pop out the ball and clean the "gunk" off the three rollers. If you are a little adventurous you can remove the two screws and seperate the mouse halves, this makes it easier to give the rollers a good cleaning. --- Ray Wallace (INTERNET,UUCP) wallace@oldtmr.enet.dec.com (UUCP) ...!decwrl!oldtmr.enet!wallace (INTERNET) wallace%oldtmr.enet@decwrl.dec.com ---

Although if you've already tried this (obvious) solution, the chances are that you've blown one of the horizontal i-r emitter/receiver pairs, most likely the orange i-r led transmitter as these do break given violent shocks. If this the case then you will have to refer servicing to qualified personell. On the other hand, check for breaks in the traces with a magnifying glass, clean any extranious dust from the internal mechanism by the i-r pairs, do a continuity check of all wires coming from the keyboard jack and, if all else fails, ATARI will replace your mouse for just $25 if you send in the dead one to an authorized service center.

I got some helpful info which showed me the right place to look. I fiddled around with the thing last night, and managed to repair it. So, here's what went wrong. Firstly, the mouse was cleaned off, but to no avail. Then, I looked at some other suggestions. The one that struck me the most likely was that it something to do with the opto-thingamajig. And it was. The rollers are on an "axle", and they have to be parallel to the plane of the mouse base, i.e. they must not jiggle up and down or left and right. The axle in my mouse was jiggling vertically. If you look carefully at both the axles, you can see that the ends are held down by plastic things (very sorry I don't know the technical names :-)). The end with the slotted wheel is held down by a plastic rod, which you can see if you look down parallel to the axle through the hole in the plastic post in which the axle end is held. Turns out that that was loose on my mouse: I found that out by comparing it with the vertical axis axle. Just put a small screwdriver into the hole at the top (looking vertically down) of the plastic post, you can push the plastic rod back down onto the axle to hold it in place. Now, about the screws. Those just hold the whole assembly, circuit board and all, down to the mouse case. The reason that fiddling with those screws works is that if you loosen them, you make clearance for the mouse ball to jiggle vertically, and that prevents the axle from jiggling. Well, that's it. Thanks again for all the helpful replies. :-) :-) David Chin IOJJ@CORNELLA.CIT.CORNELL.EDU IOJJ@VAX5.CIT.CORNELL.EDU Disclaimer: the usual, I guess "The sun in Ithaca shines mainly outdoors ..."

Sometimes the mouse would only move up, sometimes down. cleaning was of no help. its now working again, after opening-looking inside-and closing several times. but from time to time the mouse-arrow drops about an inch or so on the screen. i've also checked vor viruses-none. I think the cable is worn out. i'll try a new mouse anyway some time. ------- ------------------------------------------------------------- | Steve, Berlin. | MERTENS@DB0TUI11 | (I never said that)

The vertical axis is OK. If I move the mouse Sounds like "loose cable" to me: the mouse sends four signals to the keyboard processor; two each for horizontal and vertical movement. Whether the cursor is to be moved left or right is determined by which of the signals appears first. If one wire has no contact to the connector, the other one will appear as "first" to the keyboard processor all the time: the cursor moves in one direction only. Check all connections and plugs (inside the mouse and connector to ST) for conection. If necessary, replace connectors or cables. hase -- Hartmut Semken, Lupsteiner Weg 67, 1000 Berlin 37 hase@netmbx.UUCP Hi! (Zaphod Beeblebrox)

I have an other interpretation of this problem (based on 25 1040st in my lab and about half a dozen or more sick mouse ...) The culprit are the encoders. The heavy ball drive two wheels that pass through optical 'gates'. They each produce two signals that should be dephased by 90 degree. If this change too much, then you get your stange observed effects. Cure : First clean every thing carefully. Dust on the axes or the optical path can cause the phase error. Second, but this is an other story : with time, i have noticed that the optical system performance are changing and this must be readjusted. In principle, you find two screews (with red paint ?) at one extremity of the optical part, and they should be used to adjust the phase. Now for some reasons, the light emiters and receivers are solidly soldered on the printed board, and the screews have no effect any more. The solution we have found is this: unsolder the four wires going from the printed board to the emiter and receiver, bend them horizontaly, solder on them thin wires that you also solder to the printed board at the original place. They should make some thing like a 'Z', in such a way that you can now change the phase with the screews! Best try to look at the signals (and phase) with an oscillo ! If you need a drawing, just ask, the ptt will transmit it. If this sounds too much, and the cleaning does'nt works, then I am afraid that you better get a new mouse (logitech has one now for the atari for about 60$ [in Switzwerland ...] that should be very reliable).
