I've just found it. This was my first modded serial mouse, from 1990s. Its details are somewhere deep in my website (
http://cbm.ficicilar.name.tr/). If you adjust the variable resistor correctly, it does not interfere with the keyboard.
BTW, at the time I wasn't aware of the Amiga mouse protocol; apparently I had reinvented it, but in reverse directions. Basically, both decode the raw data from the photodiodes. For Amiga compatibility you need to switch pins 1 and 2.
Here, the original document:

Related programs and such are in the parent directory.

Hello There;
If you interested, the way to plug a PC mouse to C64 via joyport
is explained at:
http://www.physics.metu.edu.tr/~filker/cbm.html
I've included a device driver for GEOS also. So that you can use a PC
mouse with GEOS.
You can e-mail me, if you have trouble with the method.
bye,
