I did a full install of Puppy Precise 5.7.1 to my hard drive. I also have a Logitech Marble Mouse that I've been using for years in Ubuntu by adding this /etc/X11/xorg.conf file:

****************************************************
# - - - Logitech Marble Mouse Settings - - -
#
# For the sake of comments below, a Logitech Marble Mouse has buttons
# labeled from left to right: A (large), B, C, D (large).

# Preferred options for right-handed usage are:
# Left to right: A=1,normal click B=2,middle-click C=2,middle-click D=3,right-click
# Press button B (hold button while rolling trackball) to emulate wheel-scrolling.

# Preferred options for left-handed usage (saying 'alternate-click' instead of 'right click'):
# Left to right: A=3,alternate-click B=2,middle-click C=2,middle-click D=1,normal click
# Press button C (hold button while rolling trackball) to emulate wheel-scrolling.

# The trackball can scroll in two-axes, unlike a typical wheel mouse. Adjust the
# settings to constrain the scroll action to vertical-axis-only if you prefer.

# Pressing both large buttons simultaneously (b) produces a "back" action (=Cool. Finally,
# pressing and holding button B while rolling the trackball emulates wheel-rolling action.

When I try adding this file to the existing xorg.conf in Puppy (no * marks) and reboot it won't start and another OS needs to edit the xorg.conf file to make Puppy boot again.

So, how can I properly add this to Puppy's xorg.conf to make the marble mouse scroll or is there another way to get the mouse scrolling?

Does the mouse work at first (without scroll,) all you should really need to add in there is thepart

or GUI? Sorry I don't know an easy way like with my touch pad

It does work as a regular mouse with no scroll. Since it doesn´t have a wheel, it simulates scrolling by pressing the smaller left button and moving the marble up/down. In addition to the zaxis mapping I probably also need to define the buttons as there are 4 and not just 2.
