The Compucolor was an early color home computer product introduced in 1976 by Compucolor Corporation of Norcross, Georgia.
 It was a major product breakthrough in color graphics, text, and storage.
The IBM Aptiva personal computer was introduced in September 1994 as the replacement for the IBM PS/1.
 The first Aptiva models were based on the Intel 80486 CPU with later models using the Pentium and AMD CPUs.
 All systems were developed in-house except for the later E series which was developed by Acer.
 The last system was withdrawn in May 2001 without direct replacement when IBM decided to exit the home market.
 Customers were directed to the IBM NetVista, which was more targeted to business desktops.
 Most Aptiva models included a modem and a standby/hibernation feature called "Rapid Resume".
The 386SLC was an Intel-licensed version of the 386SX (32-bit internal, 16-bit external, 24-bit memory addressing), developed and manufactured by IBM in 1991.
 It included power-management capabilities and an 8KB internal CPU cache, which enabled it to yield comparable performance to 386DX processors of the same clock speed, which were considerably more expensive.
 Known inside IBM as ""Super Little Chip"" for its initials, it was used in IBM PS/2 35, 40 56 Series and in the IBM PS/ValuePoint 325T, but never gained much market share.
 This was mainly due to an agreement with Intel, in which IBM was not allowed to sell their CPUs if they were not part of a system or upgrade board.
 It was also marketed as an optional upgrade for 8086-equipped IBM PS/2 25 Series computers.
The Multi-Color Graphics Array or MCGA is a video subsystem built into the motherboard of the IBM PS/2 Model 30, introduced on April 2, 1987, and Model 25, introduced later on August 11; no standalone MCGA cards were ever made.
The PS/2 port is a 6-pin mini-DIN connector used for connecting some keyboards and mice to a PC compatible computer system.
 Its name comes from the IBM Personal System/2 series of personal computers, with which it was introduced in 1987.
 The PS/2 mouse connector generally replaced the older DE-9 RS-232 "serial mouse" connector, while the PS/2 keyboard connector replaced the larger 5-pin/180° DIN connector used in the IBM PC/AT design.
 The PS/2 designs on keyboard and mouse interfaces are electrically similar and employ the same communication protocol.
 However, unlike the otherwise similar Apple Desktop Bus connector used by Apple, a given system's keyboard and mouse port may not be interchangeable since the two devices use a different set of commands.
Video Graphics Array (VGA) is the display hardware first introduced with the IBM PS/2 line of computers in 1987.
 Through widespread adoption, the term has also come to mean either an analog computer display standard, the 15-pin D-subminiature VGA connector, or the 640×480 resolution characteristic of the VGA hardware.
OS/2 is a series of computer operating systems, initially created by Microsoft and IBM under the leadership of IBM software designer Ed Iacobucci, who later went on to found Citrix Systems, DayJet and VirtualWorks.
 As a result of a feud between the two companies over how to position OS/2 relative to Microsoft's new Windows 3.1 operating environment, the two companies severed the relationship in 1992 and OS/2 development fell to IBM exclusively.
 The name stands for "Operating System/2", because it was introduced as part of the same generation change release as IBM's "Personal System/2 (PS/2)" line of second-generation personal computers.
 The first version of OS/2 was released in December 1987 and newer versions were released until December 2001.
The IBM PS/1 is a brand for a line of personal computers that marked IBM's return to the home market in 1990, five years after the IBM PCjr.
 It was replaced by the IBM Aptiva in September 1994.
The IBM PC Series personal computer was the follow-on to the IBM PS/ValuePoint and IBM Personal System/2.
 Announced in October 1994 and withdrawn in October 2000, it was replaced by the IBM NetVista, apart from the Pentium Pro-based PC360 and PC365, which were replaced by the IBM IntelliStation.
The IBM PS/ValuePoint (or just ValuePoint) personal computer was IBM's answer to the PC clone market, where the IBM PS/2 could not compete due to price and proprietary interfaces.
 Announced in October 1992 and withdrawn in July 1995, it was replaced by the IBM PC Series 300.
