The ONANtiad headline montage
Three blue-jawed convicts in antiquated stripes dicky their cell’s lock and run, backed by sirens and searchlights’ crisscrossed play, not for the wall but straight to the Warden’s empty nighttime office, where they sit rapt before his old dual-modem MacIntosh, slapping their knees and pointing to the monitor and elbowing each other in the ribs, nibbling at inexplicably-appeared boxes of popcorn, with a Voiceover: ‘Cartridges by Modem!

Context
A film inside the montage inside Mario's film inside the novel: the escaped convicts run not for the wall but for a screen, and "Break Free of the Confinement of Your Channel Selector" sells spectation as a jailbreak into a smaller cell.

"MacIntosh" as written (see Flags).
