First of all, what is a "tablo-pen" to create a pseudo-touchscreen?
As to answer your question, it is likely the best to add enough lenghts of wire to each braid to meet your demand. I do not know if you can buy extention cable for it, however, if you've got skills just do it! It's the best way to circumvent problems. Mine is getting old but still runs well; got the first battery replaced a couple of years ago, for a staggering £15.00, that is 7200ma instead of 4800 like the original was. And was forced to buy a knew 150bg HDD little over a year ago, after I had accidentaly approached the keyboard with a speaker magnet. It is a lot faster to boot up now but, sadly, failed to back up anything prior to it, hence lost everything that wasn't backed up by fluke.
