Hi, It seems that I might have goofed on my description of the 1350 mouse. I was under the impression that it sent quadrature phase pulses right to the db9 connector. According to the technical person at the local dealer, it can be interchanged with the Amiga mouse. Subsequently, some of the net people tell me that there is a 4 bit microprocessor in the mouse that converts the chopper wheel output quadrature signal into an emulation of pushing the buttons on the joystick. I guess I'll have to check with an oscilloscope to be sure. One thing I do know is that the 1351 mouse works very well with Geos, and is worth the extra expense to get the Geos update disk. Bill
