Roland TB-303 Modification, what has been modified?

Hi, i'm new here.
i have already asked this question on gearslutz and some guys there told me to ask my question here. well, so i try ;-)

does someone have experience with tb303 modifications?
i do have a tb303 here at this moment and it has been modified but i don't know what exactly has been modified.
unfortunately there's no one else i could ask and i don't know the original owner.

i have uploaded some pictures. maybe someone can tell about what's modified by viewing the pictures.

i suppose it's a CV/Gate modification but i don't have a döpfer mcv oder similar midi-to-cv/gate converter here for a test.

the internal 303 sequencer still works but the headphone doesn't work. i suppose the headphone output does now have another function (for the CV/Gate converter) but i'm not sure.

hope someone can help.
thanks very much in advance.
cheers
frank

thats pretty painful to look at

the headphone out is now an external gate control

the gate out seems to be a failed accent in control

the cv out seems to be a failed cv in control
