PIC compatibility
From JuniperClue
P- Style pics are officially made for the M20 and M40 series, they also work in the M40e, M160, M320 when using a FPC1. Inofficially these pics also work with the M5 and M10 routers, however without any eject handle its very hard to get the pics removed. There are serveral hacks: M20_PIC_hotswapping to partitially solve this.
