Then along came the personal computer, such as IBMs with one or two 5

diskette drives, 256K bytes of RAM, 4M bytes hard drive, and a 1,200 bps modem.
A few years later, while the engineers were still playing around with mainframes, a new movement began to arise. Colleges across the US started to provide a room at the library called a “PC Lab.” IBM PC ATs and Macintosh Classics were lined up in rows, with a printer at the end of each row. Each PC would plug into some external device that would allow use of a printer. Only one PC could print at a time, so you had to keep an eye on this device to see when it was free before you sent your print job.
