Last session, when I was bored and looking to burn some hard earned money for my character, I browsed through our books and found a nice little piece that when implanted would give +3 dice on all knowledge skill checks. At the time I considered it cheap and useful and something to install when the time comes.
Now that time has come and I cannot remember the name. Or book it came from. Or anything really. Just that it was relatively cheap and gave +3 dice for knowledge checks (not a general bonus to LOG or INT though). It may have been cyberware, it may have been bioware (more likely) or maybe even nano or gene stuff.
I browsed every book I could find and googled, but with nothing to search for, it's really just going through the lists one by one. And obviously I suck at that, because I found nothing.
So does anybody know what I'm talking about and can give me a hint where to find it? I have both English and German books for page references, but a name would be enough to be able to actually do a proper search.
