NanoPEB, help me understand it

With NanoPEB and Extended basic connected, I turn on the TI computer. (NanoPEB-F18 V1) I select 2 for Extended basic but it takes me to CF7+ Manager How do I exit to Extended basic? What I am trying to do is go to Extended basic, load cassette programs and save them to a volume on the NanoPEB CF card so I can archive them. Also I believe the first two volumes have utilities on them. Do I use the third volume to store my files? Thanks! I am an old TI user but never used Disks.

I am having issues to get the Mechatronic 80 Column card to work with the NanoPeb (both individually work all okay when I test it on another system. Also I checked different type of CRU settings). I can open TI-Basic (but have a blank screen, the button the Mechatronic 80 does not work with NanoPeb inserted, without nanopeb it works to get the TI-Basic screen. I guess something todo with the graphic mode. I can run a program you can see the screen go green)
