Well, I've succeeded in hacking up my Microsoft serial mouse (the white dove bar one) to work on my Amiga. It appears to need the following to get it to talk to the Amiga; 1> removal of the uP in the Mouse 2> Add a limiting resistor for the LED's 3> Change a resistor for the Comparator's voltage divider 4> A new cord w/9 wires + shield. (salvagable from Amiga Mouse?) If there is interest I'll post the details in a few days. I need to find a couple of surface mount resistors to replace the 1/4w tacked on ones currently hanging off the board. This hack is not for the faint at heart. It requires desoldering IC's and surface mount parts. Take apart the mouse and look at the bottom of board for an idea of whats involved. -- Jeff Easton Zenith Data Systems Systems Engineer OEM Engineering easton@andrews.edu

Did you know that the PC bus mice can be hooked up to an Amiga with nothing more than a 9 pin mini-din to a DB-9 connector? No modifications to the mouse are needed, and will work with most bus-mice rather than just the microsoft mouse. I forgot the exact wiring for the connector (since I do not own an Amiga-- I gave a friend my old bus-mouse). Here is the pin-outs for the mini-din, you can probably figure out the rest from there-- otherwise leave me mail: 1 - +5v 2 - X quadrature A 3 - X quad B 4 - Y quad A 5 - Y quad B 6 - Button 1 7 - Button 2 8 - Button 3 9 - Ground E - Chassis Ground Using this arrangement makes chances of the modification working MUCH better since there is no internal changes that need to be done. If a company would ever catch wind of this, they would make a small adapter to do this and sell it for $5... - David K -- David Kessner - david@kessner.denver.co.us | do { 1135 Fairfax, Denver CO 80220 (303) 377-1801 (p.m.) | . . .

Your pinout looks like it has all the correct info, the Amiga needs the XY quadrature pairs. The only info I have is for the Microsoft serial mouse and I have seen the pinout for the PS/2 style mouse. Both of these mice have a on board microprocessor due to the "weird" interface to the computer. Does anybody have the pinout for the Microsoft bus mouse? If it puts out the quadrature pairs it would be easy. The serial mouse is the only one I had to play with. My changes basically take out the back end uP and convert it to run at 5V again. I'll post the details of the hack when I get a chance to write it up. >David Kessner - david@kessner.denver.co.us | do { -- Jeff Easton Zenith Data Systems Systems Engineer OEM Engineering easton@andrews.edu

More than half of the mice available for PC's have three buttons. I have a newer Logitech (not the wedge), that has 3. The only mouse that has two buttons and is worthwhile is the Microsoft Mouse (one of the few things they did right, IMHO). To the mest of my knoledge, all PC Bus Mice have the same pinouts. Oh. The test mouse was from an ATI VGA Wonder board. For some stupid reason they include a bus mouse with the board, and I already had the Logitech. > Your pinout looks like it has all the correct info, the Amiga needs >the XY quadrature pairs.

The signals are then sent to the PC where there is a board that deals with the signals. This is an ideal situation since it allows us to hack at it without having to figure out the microprocessor and voltage regulator. It is also standard from mouse to mouse. It's always fun to hack at hardware-- but hacking a serial mouse with surface mounted components is not for everyone in Netland. A better approach would be to hook it up into the serial port and re-write the mouse driver. But then a bus mouse is fully software compatable with the existing system. - David K -- David Kessner - david@kessner.denver.co.us | do { 1135 Fairfax, Denver CO 80220 (303) 377-1801 (p.m.) | . . .

Yes. You do have to pay about $15 extra for the interface board that is useless on an Amiga. If you can hack a serial mouse to work on an Amiga more power to you, but it is beyond most of us. I have designed/prototyped/made computers based on the 6502 and think that I am well versed on computer logic but I would rather pay $15 and risk loosing a mouse while rewiring the guts. The other option would be to find that driver that someone mentioned that allows you to use a standard serial mouse on an Amiga. This gives you the best of two worlds: a cheap mouse and a minimum (none) of hacking. - David K -- David Kessner - david@kessner.denver.co.us | do { 1135 Fairfax, Denver CO 80220 (303) 377-1801 (p.m.) | . . .

I just gave up on hacking meeses for the Amiga. Aamiga Warehouse has the Golden Image mouse for about $40. I got one last week, and installed it right away. No problems, smooth, hi-res optomechanical mouse (290ppi). Nice. Wildstar
