Fred:

There are no diffs between the piggy-backed chipset I use, and the ones 
sitting under it except the address.  If you know the hardware address for 
your /t2 which I think is in the /t2 descriptor, transfer that to the ,mem 
position at the top of joydrv_6551L.sb, where you'll find an $FF6C now, 
make your self a boot without the /t2 descriptor and the driver that goes 
with it, and replace the current joydrv_whatever with the one you just 
fixed.  Grab a db25 to db9 adaptor from one of the drawers at the shack, 
and plug in the mouse.
 
Copy this to a script
{t2|09}/X0/NITROS9/6309L2/SCRIPTS:list /dd/cmds/dbmouse

tmode .1 pau=0
load dbm-util
display c
*main
display 2 20 20
dmem -1 10EC 8 ! dump
goto main

and make it executable.  make the dbm-util it loads by merging
DMem
Dump
Display
 to dbm-util

When it runs you should see an 8 byte dump near the upper left of the 
screen, with the data in the right 6 bytes changing as you move the mouse 
around, and the first byte changing according to which button of the two 
outside buttons is pushed.  If you mouse is a logitech you should see the 
2nd byte change from an M to an L when you press the middle button the 
first time, indicating that it now knows the mouse isn't an M$ mouse, but a 
Logitech mouse.

Cheers, Gene
