On the Biocomp thing- an EK can already enhance his biocomp's performance and fail safe by one each with Psi if it is formated. No need for a device to do the same thing unless it allows him to pump it by more than 1 each. If I recall- 2 in Device might get him some nice software or grant his mini an extra die on certain attempts. The players guide has more concrete examples of what you can mechanically get out of Device ratings if you have that Velmont.
Interesting. Where did you read that? My quick scan only revealed hardtech minicomp with a mention (p.270) about biocomp not being on the open market yet. Hence the biocomp device.
Either way, the device I suggested grants +2 to a subset of the skill (hacking) and peripheral advantage so it's about right for a rank 2. I'm cool with adding that +1 to performance and failsafe.
Biocomps are in America Offline (p118). Two by Alchemy and one by Orgotek.
