IBM PCjr The IBM PCjr (read "PC junior") was IBM's first attempt to enter the home computer market. The PCjr, IBM model number 4860, retained the IBM PC's 8088 CPU and BIOS interface for compatibility, but various design and implementation decisions led the PCjr to be a commercial failure.

IBM 1400 series The IBM 1400 series were second-generation (transistor) mid-range business decimal computers that IBM marketed in the early 1960s. The computers were offered to replace tabulating machines like the IBM 407. The 1400-series machines stored information in magnetic cores as variable length character strings separated at the left and right by a special flag, called word mark. Arithmetic was performed digit-by-digit. Input and output support included punched card, magnetic tape, and high speed line printers. Disk storage was also available.

History of personal computers The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1980s. The 1981 launch of the IBM Personal Computer coined both the term "Personal Computer" and "PC". A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals. After the development of the microprocessor, individual personal computers were low enough in cost that they eventually became affordable consumer goods. Early personal computers – generally called microcomputers – were sold often in electronic kit form and in limited numbers, and were of interest mostly to hobbyists and technicians.

Extended Industry Standard Architecture The Extended Industry Standard Architecture (in practice almost always shortened to EISA and frequently pronounced "eee-suh") is a bus standard for IBM PC compatible computers. It was announced in September 1988 by a consortium of PC clone vendors (the "Gang of Nine") as a counter to IBM's use of its proprietary Micro Channel architecture (MCA) in its PS/2 series.

CDC 6400 The CDC 6400, a member of the CDC 6000 series, was a mainframe computer made by Control Data Corporation in the 1960s. The central processing unit was architecturally compatible with the CDC 6600. But in contrast to the 6600, which had 10 parallel functional units which could work on multiple instructions at the same time, the 6400 had a unified arithmetic unit, which could only work on a single instruction at a time. This resulted in a slower, lower-performance CPU, but one that cost significantly less. Memory, peripheral processor-based input/output (I/O), and peripherals were otherwise identical to the 6600.

IBM 650 The IBM 650 Magnetic Drum Data-Processing Machine is one of IBM's early computers, and the world’s first mass-produced computer. It was announced in 1953 and in 1956 enhanced as the IBM 650 RAMAC with the addition of up to four disk storage units. Almost 2,000 systems were produced, the last in 1962. Support for the 650 and its component units was withdrawn in 1969.

Poqet PC The Poqet PC is a very small, portable IBM PC compatible computer, introduced in 1989 by Poqet Computer Corporation with a price of $2000. The computer was discontinued after Fujitsu Ltd. bought Poqet Computer Corp. It was the first subnotebook form factor IBM PC compatible computer that ran MS-DOS. The Poqet PC is powered by two AA-size batteries. Through the use of aggressive power management, which includes stopping the CPU between keystrokes, the batteries are able to power the computer for anywhere between a couple of weeks and a couple of months, depending on usage. The computer also uses an "instant on" feature, such that after powering it down, it can be used again immediately without having to go through a full booting sequence. The Poqet PC is comparable to the HP 95LX/HP 100LX/HP 200LX and the Atari Portfolio handheld computers.

IBM 3745 The IBM 3745 is the latest and last of a 37xx family of communications controllers for the IBM mainframe environment. As of mid-2009 there were an estimated 7,000+ of the larger 3745 models still in active production status, down from 20,000 or more in 2007. The 3745 and associated 3746 models were once heavily used within financial, insurance and retail industries as well as within government agencies globally. However, today most organizations have migrated away from the use of 3745s. IBM's Enterprise Extender and the Communication Controller for Linux on System z (CCL) have largely displaced the older 3745s. IBM announced in September 2002 that it would no longer manufacture new 3745s, but IBM continues to support the hardware by providing worldwide maintenance service, by providing microcode releases and by supporting the associated software including NCP (Network Control Program) and the virtual telecommunications access method (VTAM). IBM has announced end-of-service dates for Japan, Europe and the Middle East, but has not yet announced end-of-service for the Americas and parts of Asia.

NEC PC-100 The NEC PC-100 was a Japanese home computer available on October 13, 1983. It operated on 8086 CPU 7 MHz, 128KB RAM, 128KB VRAM, a Japanese language capable keyboard and a two button mouse. It had three models and its color monitor, "PC-KD651", which could be used vertically or horizontally, had the price tag of 198,000 yen. Its biggest advantage over other computers of that time was its high graphical capability of 720 by 512 with a selection of 16 color out of 512 color available on its high end "model30". Its OS was MS-DOS and was also equipped with a spreadsheet program "Maruchipuran" (Multiplan) and a text editor "JS-WORD" as well as the game Lode Runner.

IBM 1402 The IBM 1402 was a high speed card reader/punch introduced on October 5, 1959 as a peripheral input/output device for the IBM 1401 computer. It was later used with other computers of the IBM 1400 series and IBM 7000 series product lines. It was adapted as the IBM 1622 Card Read-Punch for the IBM 1620 and provided the basic design for the models 2501, 2520 and 2540 equipment used with the IBM System/360 product line.

IBM System/34 The IBM System/34 was an IBM midrange computer introduced in 1977. It was withdrawn from marketing in February, 1984. It was a multi-user, multi-tasking successor to the single-user System/32. Most notably, it included two very different processors, one based on System/32 and the second based on older System/3. Like the System/32 and the System/3, the System/34 was primarily programmed in the RPG II language. One of the machine's interesting features was an off-line storage mechanism that utilized "magazines" - boxes of 8-inch floppies that the machine could load and eject in a nonsequential fashion. Borrowing mainframe features such as programmable job queues and priority levels, the System/34 ran on 64K of memory.

IBM System/360 The IBM System/360 (S/360) is a family of mainframe computer systems that was announced by IBM on April 7, 1964, and delivered between 1965 and 1978. It was the first family of computers designed to cover the complete range of applications, from small to large, both commercial and scientific. The design made a clear distinction between architecture and implementation, allowing IBM to release a suite of compatible designs at different prices. All but the incompatible model 44 and the most expensive systems used microcode to implement the instruction set, which featured 8-bit byte addressing and binary, decimal and (hexadecimal) floating-point calculations.

NCR VRX VRX is an acronym for Virtual Resource eXecutive, a proprietary operating system on the NCR Criterion series, and later the V-8000 series of mainframe computers manufactured by NCR Corporation during the 1970s and 1980s. It replaced the B3 Operating System originally distributed with the Criterion series, and inherited many of the features of the B4 Operating System from the high-end of the NCR Century series of computers. VRX was upgraded in the late 1980s and 1990s to become VRX/E for use on the NCR 9800 series of computers.

IBM System 9000 The IBM System 9000 Instrument Controller (aka CS9000 or S9000) was an IBM workstation that was announced in 1982 for use as a laboratory computer. It was based on the Motorola 68000, running at 8 MHz and was one of the few systems that used Motorola's Versabus. Input/output ports included three RS-232 serial ports, an IEEE-488 instrument port plus analog and parallel I/O. It ran a custom operating system called CSOS, standing for Computer System Operating System. IBM also offered XENIX on the S9000, but this required at least 640 KB of RAM. The machines shipped with 128 KB RAM as standard, and this was expandable up to 5.2 MB in 256 K increments.
