A Logitech sales rep. told me that they manufacture the AT&T mouse sold for
6300 and 6300+ which has 2 buttons (instead of 3 on their standard mice).
She also told me that Logitech wouldn't sell this mouse directly to the public
and I can purchase it only from the AT&T. What she couldn't answer though and
I still need to know was whether the 3-button Logitech mouse (which can be
bought at half the price of AT&T's mouse) can be soldered to a connector that
plugs into the model 302 keyboard of the 6300+ machine and will it then function
like the 2-button AT&T mouse.

PS: I am aware of Logitech mice that plug into the back of 6300+, they are not
compatible with Unix/Simultask and most other 6300+ software.

I bought a AT+T 7300 mouse at a hamfest thinking it might work with my 6300. However, it turned out to be essentialy a serial mouse. However, I was able to get it to work with my 6300 by soldering a new cable to it. It turns out that the 6300 mouse is very simple. The only circuitry in it are the four LEDs and photodiodes for the ball, and one TTL IC that debounces the switches. There are six output signals: One from each ball encoding photodiode, and one from each button. (Also power and ground inputs) On the other hand, the serial mouse I had contained a 28-pin chip that recieved the above signals, and send the data in serial form out on one line. It also had a serial input, and power and ground. What I did to the serial mouse was to disconnect the existing cable, and connect a 8-conductor cable to it. One wire went to each of the aformentioned signal sources, and the other two were for power and ground. The other end of the cable got a DB-9 connector that mated with the keyboard socket on the 6300. Note that the interface chip in the mouse no longer does anything. Also, the buttons are not debounced, but I haven't noticed any problem. All you really need to know is the pinout (pinin?) of the socket on the 6300 keyboard. If you want to try this, mail me and I will send it. I don't have it in front of me now. -- Doug Braun AT+T Bell Labs, Murray Hill, NJ m10ux!braun 201 582-7039

I purchased a Logitech Bus (three button) mouse for my 6300+. I have my system unit setting on the floor and would need an extension cable if I wanted to use the mouse with the bus card. The connector on the mouse matches the one on the AT&T keyboard so (just for fun,) I plugged the mouse into the keyboard. Guess what? It worked. BUT if you want to use most software with it, you will somehow have to purchase the AT&T mouse driver. The exception to this is Microsoft Windows and software packages which use the windowing environment directly. If you know of a different mouse.com driver for the AT&T keyboard mouse you could use it instead. With the bus mouse, I have more options which may help me with making software compatible with the mouse if I ever get an extension cable. The mouse came with lots of software, most of it works with the AT&T mouse driver. The exceptions are the Logitech mouse drivers and software which reconfigures them. Maybe the new Logitech Serial mouse (with the DB9 connector for the AT) will work the same way. Disclaimer: These are not the official views of AT&T or Logitech.
