Tactical Computer, Some questions Options

[GrinderTheTroll]

I was reading the text in MM.47 on the TacComputer and am confused about a few things, maybe you all can shed some light on them.

Here's the way I understand it:

You get 5 "free" ports for your 5 basic sences (smell, sight, taste, touch, sound). There is no essence cost or requirement for these.

You can get either:

A dedicated port that is "locked" into using some data input sorce (radio, telephone, etc.) and cost .1 essence and 10,000 nuyen each.

OR

A generic port that can be reassigned to other sources on the fly, costs .1 essence , only 5,000 nuyen, but requires a 50MP "tactal sense" program to understand the input. Basically it's cheaper but requires a hardware driver.

My confusion is the wording of the text that makes me unsure if *ALL* ports (free, dedicated or generic) would require the 50MP programs to function. This would make no sense based soley on the fact that a dynamic generic port would be cheaper that a dedicated port.

Is my inital read correct on this? Any thoughts or comments?

Thanks.
