So the core book mostly talks about limits of 6 when it comes to matrix attributes of Commlinks and the programs on them. But I've seen some posts here on the forums as well as some of the gear listings for some NPCs (Street Legends and Street Legends Supplemental comes to mind) where the attributes go higher...I can't recall seeing any higher than 9 without being Nexi though. Can someone point me in the direction of the crunchy rules details for this? I'd assume Unwired, but so far I haven't found it. Could be I'm looking in the wrong part of the book too. I'm looking specifically for how to make your own custom commlinks/software with the higher ratings as well as possible rules for characters starting with them. Any advice?
