according to the pin-out in the manual:
This is a Spectrum digital variant more similar to the Patkány, pictures thanks to World Oof Spectrum:
Observe the plain cable and the strain relief boot at the mouse side, it is the very same one of the Patkány.
It had the same polyurethane ball with the same diameter of 32mm, but not the polyurethane pulleys. At least they have not been mentioned on the three sources we have now

Edit: I have found that there was a "Digimouse" and an "Anamouse", so it stands for "digital mouse", a Joystick-mouse like the Patkány.
