got my tiger mask today WOO WOO from TA

haven't got it set up yet, was looking at the back and there are several eletronic NIC looking tings that have what look like ethernet female jacks, was wondering, is there some device that can be used to plug in to these, to "tweak" the settings?

looks to me like they are ports to plug in a controller device, kind of like the OBDC handhelds one uses to diagnose auto engine troubles....

any hints? BTW the machine is B+YOU+TI-FULL, perfect condition looks brand spanking new.

Can't wait to play it!! Thanks TA!!
