I have several, not for sale though. They are used for my Lilith workstation. Tried to get them working on a serial port, using an existing serial mouse, but did not manage. Somehow there is a difference in the quadrature signals, I did not investigate further. I reconstructed its schematic, together with the rest of the Lilith, results are here : ftp://jdreesen.dyndns.org/ftp/Emulith/CAD/extern.sch Eagle CAD format, mouse is in extern.sch.

Anyone manage to get one working on a standard serial port, or have the pinout? Thanks! -Ben

Yes, or at least something similar (a Depraz mouse) on my Whitechapel MG1 It is not a serial mouse, in fact connecting it to an RS232 port is likely to damage it. It runs on 5V. There are 2 versions. The commonb one has quadrature outputs, on a DE9 plug. The pinout is : 1 +5V 2 Y2 3 Y1 4 X2 5 X1 6 Ground 7 Middle button 8 Right button 9 Left button The other, much less common, versions is serial, but not synchornous serial. The 7 signals (3 buttons, 4 quadratur signasl) are fed ito a 49021 shift register. Only 5 wires are needed, I am not sure what the connector is (DE9 again?). Anyway, the minimal data I ahve suggests : 1 Load (signals into SR) 2 clock 3 +5V 4 Ground 5 Serial data out The host machine provides the clock and load singals, they are inptus ot the mouse, -tony
