Large computer suffering RAM famine? (9)
I believe the answer is:
mainframe
'large computer' is the definition.
(I've seen this before)
'suffering ram famine?' is the wordplay.
'suffering' indicates an anagram.
'ram'+'famine'='ramfamine'
'ramfamine' anagrammed gives 'MAINFRAME'.
(Other definitions for mainframe that I've seen before include "Principal computer" , "Mar famine (anag.)" , "powerful computer" , "Large central computer" , "Computer's central processing unit" .)
