 * Home * Hardware * IBM PC**

the progenitor of the [|PC compatible] hardware platform. The original IBM version was model number **5150** with Intel 8088 running at 4.77 MHz and 16 or 64 [|Kibibyte] of RAM, introduced on August 12, 1981. Pricing started at US$1,565 (equivalent to $4,080 in 2015) for a configuration with 16 K RAM, [|Color Graphics Adapter], and no disk drives. Most 5150s had one or two 5.25-inch [|floppy disk] drives, either [|single-sided double-density] (SSDD) or [|double-sided] double-density (DSDD). The [|XT] with 256 K RAM (expandable up to 640 K) and built-in [|hard drive] followed in 1983, the [|AT] with [|80286] processor @ 8 MHz in 1984, and [|PS/2] in 1987, with the follow-on of the [|IBM PC series] until 2000, along with 32-bit x86 compatibles. The term "IBM PC compatible" is not commonly used any more because most current mainstream desktop and laptop computers are based on the PC architecture with x86-64 processor and IBM no longer making PCs || toc =Project Chess= In July 1980, [|William C. Lowe] assembles the members of "Project Chess", known as the "Dirty Dozen", the twelve engineers chosen to design and build a prototype personal computer, in [|Boca Raton, Florida]. [|Don Estridge] is project manager, Jack Sams heads the software effort.
