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 judge whether this defines the answer.
'probe one seti designed' is the wordplay.
'probe' becomes 'dig' (I can't justify this - if you can you should believe this answer much more).
'one' becomes 'i' (Roman numeral).
'designed' is an anagram indicator (designed with the letters).
'seti' is an anagram of '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" .)
