Get ready for computer to use probe - one SETI designed (8)
I believe the answer is:
digitise
'get ready for computer' is the definition.
I can't tell whether this definition defines the answer.
'probe one seti designed' is the wordplay.
'probe' becomes 'dig' (I am not sure about this - if you are sure you should believe this answer much more).
'one' becomes 'i' (Roman numeral).
'designed' indicates anagramming the letters (designed with the letters).
'seti' with letters rearranged gives 'tise'.
'dig'+'i'+'tise'='DIGITISE'
'to use' acts as a link.
Can you help me to learn more?
(Other definitions for digitise that I've seen before include "To transcribe data" , "Put into a form suitable to a computer" , "Convert into binary form" .)
