 The '''IBM 5150''' was [[International Business Machines|IBM]]'s entry into the [[personal computer]] marketplace; the '''IBM PC'''. It was introduced in stores on 1981-08-12.
-The original configuration had a [[motherboard]] designed for up to 64KB of [[Dynamic RAM|RAM]], and a cassette [[tape drive]], but could be expanded to include a [[Disk#Low-cost disks|diskette drive]], and a [[Disk#Recent developments|hard disk]].

 At the beginning they were advertised for around $1,600 for a unit with just 16KB of RAM and a keyboard[http://www.vintage-computer.com/ibm_pc.shtml]. Retail would be around $1,000 though[http://classiccmp.org/pipermail/cctech/2013-July/106735.html], or maybe more likely in the $1,300 - $1,400 range[http://classiccmp.org/pipermail/cctech/2013-July/106743.html]).
-In practice you would add a at least a video adapter, probably some RAM, and a floppy disk drive. Then the price would be quite different. Back then, both types of disk drives were of the 5 1/4" full height form factor.
+In practice you would add a at least a video adapter, probably some RAM, and a floppy disk drive. Then the price would be quite different. Back then, both types of disk drives were of the 5 1/4" full height form factor, single sided or double sided.
 IBM made the PC an open standard, publishing not only schematics, but also including a [[BIOS]] [[listing]] in the technical reference. When people wished to build clones of the IBM PC, IBM would license them for a 5% royalty fee, which not only made the PC a popular platform to clone, but also with the available schematics, allowed for everyone to be pin compatible with the ISA slots, creating a thriving hardware expansion business.

DOS included a simple version of BASIC, known as disk BASIC, and a graphics version known as Advanced BASIC (BASICA.COM)
 The IBM PC, also established the 8 bit expansion slot, or [[Industry Standard Architecture|ISA]] bus standard as it was later called.
