AppleTalk: One Damaged Macintosh Can Crash a Network
If a broken but turned-on Macintosh is attached to a network, can it cause
the network to crash? For example, if a screen is flickering or
intermittently goes out, can that Macintosh cause a network bomb or cause
other computers on the network to crash?
In addition to a bad LocalTalk box or cable, it's possible for a damaged
Macintosh to send out enough interference on a network to cause the network
to crash. It wouldn't cause other systems to crash, though.
