The Amiga 1200, or A1200, was Commodore International's third-generation Amiga computer, aimed at the home market. It was released in October 1992, at a base price of £399 in the United Kingdom and $599 in the United States.[1]
Like its predecessor, the A500, the A1200 is an all-in-one design incorporating the CPU, keyboard, and disk drives (including, unlike the A500, the option of an internal hard disk drive) in one physical unit.
The system competed directly against the Atari Falcon, but intended as a home computer it inadvertently also competed against entry level PCs and 16-Bit game consoles. During the first year of its life the system reportedly sold well, but not comparable to game consoles and in a desire to compete Commodore launched the Amiga 1200-compatible Amiga CD32 game console in June 1993.
The future looked good for the Amiga 1200 platform, but due to poor financial management Commodore ran into cash flow problems and soon went bankrupt - this despite the fact that the Amiga 1200 and Amiga CD32 both were successful and profitable products. With Commodore’s demise, the Amiga 1200 almost disappeared off the market, but the system got a second chance with Escom's re-launch in 1995.
The new Escom A1200 was almost identical to the original model, the difference being an updated operating system and a floppy disk drive from a different manufacturer. Re-launched at a price of one-hundred and fifty dollars above what it had been sold for two years prior (equal to the 1992 launch price) potential buyers found that the system provided little value and largely ignored the system.
After Escom's financial problems, the Amiga 1200 was taken off the market some time during 1996.

[edit] Popularity
Although a significant upgrade, the A1200 proved not to be as popular as the earlier Amiga 500. There were a number of reasons for this:
- While its graphics capabilities stood up well in comparison to the competition, the Amiga no longer commanded the lead it had in earlier times.
- The Amiga's custom chips cost more to produce than the commodity chips utilized in PCs, making the A1200 more expensive, relative to PCs, than earlier Amiga models.
- Fewer retailers carried the A1200, especially in the United States.
- The Amiga 1200 received bad press for being incompatible with a number of Amiga 500 games.
- Some industry commentators felt a 68020 CPU was too old and slow to be competitive, and that the machine should have been fitted with at least an '030. Complaints were also made about the capabilities of the AGA chipset. Commodore was working on a much improved version of the chipset, codenamed "AAA", when it went bankrupt.
Although Commodore never released any official sales figures, it is estimated that Commodore shipped fewer than 1 million A1200s worldwide before going bankrupt in April 1994[citation needed].
[edit] Technical information
[edit] Processor and RAM
The A1200 utilized a Motorola MC68EC020 CISC CPU (roughly four times faster than the 68000 processor in the Amiga 500). It is noteworthy that, like the 68000, the 68EC020 had a 24-Bit expansion bus; allowing for a theoretical maximum of 16 MiB of memory.
It shipped with 2 MiB of Chip RAM. Chip RAM could not be expanded beyond those 2 MiB, but an additional 8 MiB of Fast RAM could be added through use of the trapdoor expansion slot.
Later, various accelerators featuring 68020, 68030, 68040, 68060 and PowerPC processors were made available by third parties. Such accelerators did not only have faster CPUs but also more and faster memory (on the most expensive boards 256 MiB on two 128 MiB SIMMs), real time clocks, IDE and SCSI ports and other enhancements.
[edit] Graphics and sound
The A1200 shipped with Commodore's third-generation chipset, the Advanced Graphics Architecture or AGA. As the name implies, the AGA chipset had superior graphical abilities in comparison with the earlier chipsets, but not much else.
The A1200 also offered improved audio abilities which allowed for higher sampling rates for sound playback.
[edit] Peripherals and expansion
In addition to the ports common to all earlier Amiga models, the A1200 featured a memory/CPU slot, a PCMCIA slot and a feature unique to the A1200 – a clockport.
The clockport was a remnant of an abandoned design feature (real time clock and Chip RAM expansion). Third party developers put it to ingenious use by creating an array of innovative expansions for the A1200 such as audio cards (Delfina) and even a route to expanding the A1200 with USB (Subway USB).
If one was willing to forgo the A1200's form-fitting case, PCI and Zorro busses could also be added to the A1200, allowing graphics, sound and network cards to be added. Eyetech and Power Computing built and supplied many PC tower kits to 'tower up' the A1200 and in essence convert it to a 'big box' Amiga, even allowing for use of PC AT Keyboards.
One problematic factor for expanding the A1200 was the rather limited 23 watt power supply. Hard drives and even external floppies could stress the power supply too much. This was usually alleviated by 'towering up' the Amiga as it allowed for use of much more capable power supplies. The problem could also be mitigated by replacing the A1200's factory default power supply with the much more powerful A500 power supply.
[edit] Software
The first incarnation of the A1200, by Commodore, was bundled with AmigaOS 3.0 that used Kickstart 3.0 (39.106), CrossDOS – allowing for reading & writing MS-DOS format disks - various utility programs including calculator and screenblanker, and limited-time offers of Deluxe Paint IV AGA (a 2D paint & animation program) and Final Copy (a full featured word processor).[2]
The Amiga Technologies/Escom version shipped with AmigaOS 3.1 and Kickstart 3.1, and used to be bundled with various third-party programs such as Scala, Wordworth and so on.

[edit] Trivia
- The Escom A1200 models were fitted with PC-style 'High Density' internal drives that had been downgraded to Double Density drives. This resulted in some software not working. (PC style drives do not supply a "ready" signal, which signals if there is a floppy in the disk drive.)[3]
- The A1200 far outlived its shelf life, despite being only a desktop-based home computer. This was made possible by third party expansions released long after the Amiga disappeared from shops.
- Because the unit's built-in memory was shared between the CPU and the sound and video chips, making it slow, adding additional RAM (so called "Fast RAM", which wasn't shared) increased the A1200's speed to a larger degree (double: ~2.26x) than one would expect on, say, an IBM PC.
