Take a chance going up to Oxford in secluded place with small computer
I believe the answer is:
notebook
'small computer' is the definition.
(I've seen this before)
'take a chance going up to oxford in secluded place' is the wordplay.
'take a chance' becomes 'bet' (I've seen this in other clues).
'going' becomes 'on' (both can mean functioning or activated).
'up' shows that the letters should be reversed in order (in down clue: letters go upwards).
'to oxford in secluded place' becomes 'ook' (I can't explain this - if you can you should believe this answer much more).
'bet'+'on'='beton'
'beton' reversed gives 'noteb'.
'noteb'+'ook'='NOTEBOOK'
'with' is the link.
Can you help me to learn more?
(Other definitions for notebook that I've seen before include "Bigger than diary, smaller than laptop" , "Memo pad" , "jotting resource" , "Small compact portable computer" , "Jotter - portable computer" .)
