Plant erasing non-users initially from restored computer system (8)
I believe the answer is:
platform
'computer system' is the definition.
(computer hardware)
'plant erasing non-users initially from restored' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'from' is 'form' which is located in the answer.
The remaining letters 'plat' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for platform that I've seen before include "Raised level surface" , "Stand (taken by speakers?)" , "Stage, podium" , "Raised area for speakers" , "Stage for speaker or rail traveller" .)
