General Purpose Microcomputers

Now we come to the third We of Public Access Computer from that list I gave several pages back: the General Purpose Micro. I'm going to be talking here about IBMs and MS-DOS machines, although nowadays we're seeing more and more Macs out in the open for public use. Of course, all techniques I discuss can be translated to any computing envirorunent.

Let's say you call up your local library and make an appointment to use a computer there, for word processing or business or whatever. Ordinar-ily these are nonnetwork machines, although if there's more than one they may be connected to the same printer, or to some other peripheral. At col-leges, the word  processing software may be on a non-writable disk - on some sort of mainframe or minicomputer. There are also businesses set up now where people can go to rent time on a com-puter to type up their r6sum6s or reports, and have them printed out on a good quality printer. Set-ups such these can be exploited to the hacker's benefit.
