Meee with more questions~~

I am probably going to ask this every pertainable mission but Are there computers that can be accessed during the Arrivals mission and can Tech do some slicing/hacking for info? And if so, what can he dig up? Or would this go along the same lines as the info the Doctor's asked about above?

Also wondering if the location is big enough that there'd be maps to download from said computer or if they're just small affairs.
