Legion of Super-Heroes Annual #1 - "Dammit."
In the Computo post down the page, crinosg requested a look at pre-Crisis Duo Damsel's more seriously handled reaction to the death of her third body.
That's in Legion of Super-Heroes Annual #1, in which Brainiac 5 uses the Computo technology in an attempt to help a comatose little girl, Danielle Foccart. Results: Predictable - Computo gets loose and takes control of LOSH's all-automated headquarters, whose systems begin attacking the Legionnaires - and locking out any potential help. One page, not my scan.
