Hack getting to grips with right computer (6)
I believe the answer is:
laptop
'computer' is the definition.
(laptop computer is a kind of computer)
'hack getting to grips with right' is the wordplay.
'hack' becomes 'lop' (I've seen this before).
'getting to grips with' is an insertion indicator.
'right' becomes 'apt'.
'lop' placed around 'apt' is 'LAPTOP'.
(Other definitions for laptop that I've seen before include "Small computer" , "Portable computer" , "Aid for businessman" , "Type of computer" , "Some work on this" .)
