List of IBM Personal Computer models

From Wikipedia, the free encyclopedia

The original IBM Personal Computer, with monitor and keyboard

The IBM Personal Computer, commonly known as the IBM PC, spanned multiple models in its first generation (including the PCjr, the Portable PC, the XT, the AT, the Convertible, and the /370 systems, among others), from 1981 to 1987. It eventually gave way to many splintering product lines after IBM introduced the Personal System/2 in April 1987.

A company spokesman said the boost in memory [to 256 KB] was needed to accommodate the demand for more sophisticated applications, such a windowing. He added that although the 64K-byte systems will remain in production, the company eventually plans to phase them out.

IBM's recent announcement that it will formally discontinue its PC XT line and eventually phase out its PC AT came as no surprise to many corporate users. [...] William Lowe, president of IBM's Entry Systems Division in Boca Raton, Fla., told Wall Street analysts on June 30 that the only remaining XT, the XT 286, will be discontinued within three months and that IBM is working with dealers and large accounts to determine how many more ATs it will make to fill orders.

The new floppy disk-based versions of the PC XT basically just strips the 10MB hard disk from the earlier unit. The machines come with base memory of 256KB and are available in either single or dual 360 KB diskette versions. A single diskette unit with keyboard and 256 KB of main memory is priced at $2,270, while the dual diskette version is priced at $2,570. A fully configured PC XT with 256 KB of RAM, a 360 KB diskette, keyboard, monochrome monitor and adapter, and operating system comes in at about $2,860.

IBM doesn't advertise the PS/2 as a factory-floor machine, yet the PS/2's backplane bus structure, Micro Channel, appeared in a factory-floor computer before the PS/2 itself came on the market. People who examined the IBM 7552 Gearbox, ostensibly a factory-hardened version of the AT, notice something odd about the unit's bus: It had more bus lines than could be accounted for by the AT bus. The extra lines turned out to be the 16-bit Micro Channel. Nobody at IBM said anything about it at the time, because PS/2 hadn't yet been introduced.
