Boring old computer types entertaining person with drinks (11)

I believe the answer is:

cardpunches

'boring old computer types' is the definition.
(device boring holes through cards)

'entertaining person with drinks' is the wordplay.
'entertaining person' becomes 'card' (card can mean an eccentric person).
'with' means one lot of letters go next to another.
'drinks' becomes 'punches' (punch is a kind of drink).
'card'+'punches'='CARDPUNCHES'

(Another definition for cardpunches that I've seen is " old data recorders".)

I've seen this clue in The Times.
