Amiga CD32: The Amiga CD32, styled "CD" and code-named "Spellbound", is the first 32-bit home video game console released in western Europe, Australia, Canada and Brazil.  It was first announced at the Science Museum in London on July 16, 1993, and was released in September of the same year.  The CD32 uses CD-ROM media, and was developed by Commodore, creator of the Commodore Amiga computer.  It was based on Commodore's Advanced Graphics Architecture chipset, and is of similar specification to the Amiga 1200 computer.  Using third party devices, it is possible to upgrade the CD32 with keyboard, floppy drive, hard drive, RAM and mouse, turning it into the equivalent of an Amiga 1200 personal computer.  A hardware MPEG decompression module for playing Video CD was also released.  In the Christmas period following its launch, the CD32 accounted for 38% of all CD-ROM drive sales in the UK, exceeding sales of the Mega-CD; however, it was soon overshadowed by CD-ROM based games consoles from other companies, and was discontinued as Commodore went into bankruptcy.

Grand Monster Slam: Grand Monster Slam is a computer game for the Commodore Amiga, Commodore 64, Atari ST and PC.  It is heavily based on the 1985 arcade game Penguin Wars.  In Amiga Power's first All Time Top One Hundred in the inaugural 'Issue 0', it was declared to be the 100th best Amiga game of all time.  It never reappeared in the top 100 and its initial inclusion was said to be due to the insistence of a single writer.  In March 2017 the source code of the game became available via the Internet Archive.

Amiga Enhanced Chip Set: The Enhanced Chip Set (ECS) is the second generation of the Amiga computer's chipset, offering minor improvements over the original chipset (OCS) design.  ECS was introduced in 1990 with the launch of the Amiga 3000.  Amigas produced from 1990 onwards featured a mix of OCS and ECS chips, such as later versions of the Amiga 500 and the Commodore CDTV.  Other ECS models were the Amiga 500+ in 1991 and lastly the Amiga 600 in 1992.

Amiga 500: The Amiga 500, also known as the A500, is the first low-end Commodore Amiga 16/32-bit multimedia home/personal computer.  It was announced at the winter Consumer Electronics Show in January 1987at the same time as the high-end Amiga 2000and competed directly against the Atari 520ST.  Before Amiga 500 was shipped, Commodore suggested that the list price of the Amiga 500 was US$595.95 without a monitor.  At delivery in October 1987, Commodore announced that the Amiga 500 would carry a US$699/£499 list price.  In Europe, the Amiga 500 was released in May 1987.  In the Netherlands, the A500 was available from April 1987 for a list price of 1499 HFL (US$730 in 1987).

Lambda 8300: The Lambda 8300 was a Sinclair ZX81 clone from Lambda Electronics Limited of Hong Kong.  It was not an exact clone as it had a modified ZX81 ROM, but could be fitted with a ZX81 compatible ROM.  It came with 2K RAM (expandable to 16 or 32 K), and a sound and joystick port.  Specifically, it used a Z80A microprocessor at 3.25 MHz.  It was identical to the DEF 3000, PC 2000, Marathon 32K, IQ 8300, PC 8300, Power 3000, Unisonic 8300, Futura 8300, Basic 2000 and Basic 3000.

Commodore User: Commodore User, known to the readers as the abbreviated "CU", was one of the oldest British Commodore magazines.  A publishing history spanning over 15 years, mixing content with technical and video game features.  Incorporating "Vic Computing" in 1983 by publishers EMAP, the magazine's focus moved to the emerging Commodore 64, before introducing Amiga coverage in 1986, paving the way for Amiga's dominance and a title change to "CU Amiga" in 1990.  Covering the 16-bit computer, the magazine continued for another eight years until the last issue was published in October 1998 when EMAP opted to close the magazine due to falling sales and a change in focus for EMAP.  The magazine also reviewed arcade games.

Amiga: The Amiga is a family of personal computers sold by Commodore starting in 1985.  The original model was part of a wave of 16 and 32 bit computers that featured 256KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio over 8-bit systems.  This wave included the Atari ST—released the same year—Apple's Macintosh, and later the Apple IIGS.  Based on the Motorola 68000 microprocessor, the Amiga differed from its contemporaries through the inclusion of custom hardware to accelerate graphics and sound, including sprites and a blitter, and a pre-emptive multitasking operating system called AmigaOS.

PC 8300: PC 8300 was a Sinclair ZX81 clone from China with rubber keys, joystick port and monitor port.  Identical to Lambda 8300 and Power 3000.

Commodore USA: Commodore USA, LLC was a computer company based in Pompano Beach, Florida, with additional facilities in Fort Lauderdale, Florida.  Commodore USA, LLC was founded in April 2010.
