1st Stage Ports

As I am comparing regulators, I notice that the number of HP and LP ports varies on the stages. Can someone give a quick list on what I should expect to be plugging into these ports? I am asking because I am weighing buying a AI wireless computer versus a non AI one. If I get an AI one, being the engineer I am, I would want a redundant SPG also on a hose clipped off. I know inflators, regulators and SPG, but what else and which are on HP and which are on LP? Thanks!

you probably have it already...nothing special
HP = SPG, AI Transmitter etc
LP = 2nd stage regs, Inflators (bcd, drysuit, etc) and so on

Thanks! Now I know I can fit a SPG and an AI transmitter on the two HP ports my regs I want have. Thanks again!
