Instead, the Crackdown of 1990 would concern itself with the computerized version of forbidden data. The crackdown itself, first and foremost, was about BULLETIN BOARD SYSTEMS. Bulletin Board Systems, most often known by the ugly and un-pluralizable acronym "BBS," are the life-blood of the digital underground. Boards were also central to law enforcement's tactics and strategy in the Hacker Crackdown.
A "bulletin board system" can be formally defined as a computer which serves as an information and message-passing center for users dialing-up over the phone-lines through the use of modems. A "modem," or modulator-demodulator, is a device which translates the digital impulses of computers into audible analog telephone signals, and vice versa. Modems connect computers to phones and thus to each other.
Large-scale mainframe computers have been connected since the 1960s, but PERSONAL computers, run by individuals out of their homes, were first networked in the late 1970s. The "board" created by Ward Christensen and Randy Suess in February 1978, in Chicago, Illinois, is generally regarded as the first personal-computer bulletin board system worthy of the name.
Boards run on many different machines, employing many different kinds of software. Early boards were crude and buggy, and their managers, known as "system operators" or "sysops," were hard-working technical experts who wrote their own software. But like most everything else in the world of electronics, boards became faster, cheaper, better-designed, and generally far more sophisticated throughout the 1980s. They also moved swiftly out of the hands of pioneers and into those of the general public. By 1985 there were something in the neighborhood of 4,000 boards in America. By 1990 it was calculated, vaguely, that there were about 30,000 boards in the US, with uncounted thousands overseas.
Computer bulletin boards are unregulated enterprises. Running a board is a rough-and-ready, catch-as-catch-can proposition. Basically, anybody with a computer, modem, software and a phone-line can start a board. With second-hand equipment and public-domain free software, the price of a board might be quite small—less than it would take to publish a magazine or even a decent pamphlet. Entrepreneurs eagerly sell bulletin-board software, and will coach nontechnical amateur sysops in its use.
Boards are not "presses." They are not magazines, or libraries, or phones, or CB radios, or traditional cork bulletin boards down at the local laundry, though they have some passing resemblance to those earlier media. Boards are a new medium—they may even be a LARGE NUMBER of new media.
Consider these unique characteristics: boards are cheap, yet they can have a national, even global reach. Boards can be contacted from anywhere in the global telephone network, at NO COST to the person running the board—the caller pays the phone bill, and if the caller is local, the call is free. Boards do not involve an editorial elite addressing a mass audience. The "sysop" of a board is not an exclusive publisher or writer—he is managing an electronic salon, where individuals can address the general public, play the part of the general public, and also exchange private mail with other individuals. And the "conversation" on boards, though fluid, rapid, and highly interactive, is not spoken, but written. It is also relatively anonymous, sometimes completely so.
And because boards are cheap and ubiquitous, regulations and licensing requirements would likely be practically unenforceable. It would almost be easier to "regulate," "inspect," and "license" the content of private mail—probably more so, since the mail system is operated by the federal government. Boards are run by individuals, independently, entirely at their own whim.
For the sysop, the cost of operation is not the primary limiting factor. Once the investment in a computer and modem has been made, the only steady cost is the charge for maintaining a phone line (or several phone lines). The primary limits for sysops are time and energy. Boards require upkeep. New users are generally "validated"—they must be issued individual passwords, and called at home by voice-phone, so that their identity can be verified. Obnoxious users, who exist in plenty, must be chided or purged. Proliferating messages must be deleted when they grow old, so that the capacity of the system is not overwhelmed. And software programs (if such things are kept on the board) must be examined for possible computer viruses. If there is a financial charge to use the board (increasingly common, especially in larger and fancier systems) then accounts must be kept, and users must be billed. And if the board crashes—a very common occurrence—then repairs must be made.
Boards can be distinguished by the amount of effort spent in regulating them. First, we have the completely open board, whose sysop is off chugging brews and watching re-runs while his users generally degenerate over time into peevish anarchy and eventual silence. Second comes the supervised board, where the sysop breaks in every once in a while to tidy up, calm brawls, issue announcements, and rid the community of dolts and troublemakers. Third is the heavily supervised board, which sternly urges adult and responsible behavior and swiftly edits any message considered offensive, impertinent, illegal or irrelevant. And last comes the completely edited "electronic publication," which is presented to a silent audience which is not allowed to respond directly in any way.
