*maxscrl.exe is for MAX-913 scroll mouse. Drivers for PS2 and serial versions.
The USB type is detected as a HID device , works with the generic Windows drivers.
Includes scrolling software with 3D.
*Optimaus.exe is a MAX-600 optical mouse driver, I think.
this site may have Maxtron drivers in future - the page needs fixing.
