No usb adaptor, mine is older. I think there was a ps/2 to rs232 convertor
included, but I never used it, except for some tests when I bough it.

It is extreme, yes. But I can move my finger fast in normal use and see
how the cursor doesn't quite follow me. And... in windows it does follow
my movement, therefore, it should do the same in Linux. It is not a
problem of this mouse, another computer with a standard Microsoft mouse
and SuSE 7.3 (ie, old) does the same thing. It must be something handling
the ps/2 port.
It is not serious, but I notice it. So I move my finger a trifle slower,
but I wonder at the "why" :-)

No, different model. This is a "Trackman Marble+", three buttons, the
middle one a wheel that can be pressed (acting as the middle button) or
rotated, which XFree interprets as buttons 4 and 5:
Option "ZAxisMapping" "4 5"
This wheel came in two "flavours": one that moves smoothly, and another
in "clicks". The ball is red with seemingly random black dots. And I have
seen it used by mechanics with greased hands :-)
The wheel movements are interpreted usually as scroll up/down, and that
movement sometimes bounces a line in the wrong direction.
