Rocky's Boots is an educational logic puzzle game by Warren Robinett and Leslie Grimm, published by The Learning Company in 1982.
 It was released for the Apple II, the CoCo, the Commodore 64 the IBM PC and the IBM PCjr.
 It was followed by a more difficult sequel, "Robot Odyssey".
 It won Software of the Year awards from Learning Magazine (1983), Parent's Choice magazine (1983), and Infoworld magazine (1982, runner-up), and received the Gold Award (for selling 100,000 copies) from the Software Publishers Association.
 It was one of the first educational software products for personal computers to successfully use an interactive graphical simulation as a learning environment.
The IBM 711 was a punched card reader used as a peripheral device for IBM mainframe vacuum tube computers and early transistorized computers.
 The 711's read mechanism was based on the IBM 402's and could read 150 cards per minute (250 cards per minute on the IBM 7090).
 Announced on May 21, 1952, it was first sold with the IBM 701.
 Later IBM computers that used it were the IBM 704, the IBM 709, and the transistorized IBM 7090 and 7094.
 Variants of the 711, the IBM 712 and the IBM 714 were used with the IBM 702 and IBM 705 computers.
River Raid is a scrolling shooter video game designed and developed by Carol Shaw, and published by Activision in 1982 for the Atari 2600 video game console.
 Over a million game cartridges were sold.
 Activision later ported the title to the Atari 5200, ColecoVision, and Intellivision game consoles, as well as to the Commodore 64, IBM PCjr, MSX, ZX Spectrum, and Atari 8-bit family home computers.
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.
On the original IBM Personal Computer, and the IBM PCjr, an interface was provided to allow the use of a compact cassette tape recorder to load and save data and programs.
 In fact until the PC was discontinued in 1987, there was Model 104 offered that was a 5150 from IBM without a floppy disk drive.
The CCE MC-1000 was an obscure Home computer produced in Brazil by CCE (Comércio de Componentes Eletrônicos).
Digger is a computer game released by Canadian developer Windmill Software in 1983 for the IBM PC.
 "Digger" is similar in design to the 1982 arcade game "Mr. Do!
".
 "Digger" was developed by Rob Sleath, the primary developer of Windmill games.
 In 1984, "Digger" was converted to run on IBM PCjr and IBM JX, the Japanese version.
 The last original version was released for Hyperion, a Canadian computer running at 6 MHz.
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 JX (or JXPC) was a personal computer released in 1984 into the Japanese, Australian and New Zealand markets.
 Designed in Japan, it was based on the technology of the IBM PCjr and was designated the IBM 5511.
 It was targeted in the Australian market towards the public education sector rather than at consumers, and was sold in three levels: JX (64Kb), JX2 (128Kb) and JX3 (256kb).
 Upgrades were available to both 384kb and 512kb.
