= S =
scrool /skrool/ n.
[from the pioneering Roundtable chat
system in Houston ca. 1984; prob. originated as a typo for
`scroll'] The log of old messages, available for later perusal or
to help one get back in synch with the conversation. It was
originally called the `scrool monster', because an early version
of the roundtable software had a bug where it would dump all 8K of
scrool on a user's terminal.
