capabilities of HP prime solver

[bhennink]

My HP27 died due to a failing keyboard and I am lookin for a replacement. Tried the 50G which was a mismatch for me and I did not like it at all. I do not like RPN.

Another calculator that attracts me is the 'prime'. I have downloaded the emulator to play a bit.
I found the solver in the emulator and a bundle of 10 possible rows for equations.
Am I right you can create a bundle of max 10 equations?

Does this mean only one bundle/set? Or can you create more bundles?

like:

passive component caculations
Filter calculations
Stepup converter calculations
Thermal calculations
etc.

it this is possible, that would be extremely helpfull

Sometimes it is petty difficult to find your way in a manual if you have no clue where to search.
I hope to find some more info here before I decide.
