Yeah, when I undid the mod I desoldered and removed the resistors, then used telco wire to patch the cuts.

I should of photographed it after but I kinda don't want to completely dismantle the system again.

I really have no idea what the mod does besides add resistance. It's not even a resistor network. It's just a bunch of resistors inline. That I'm aware of there was not changes to the parallel port or ProFile standard either.
