A1200
Popularity
Although it was a major upgrade, the A1200 proved not to be as popular as the first A500, although it was the second most popular model out Amiga. Reasons why it was not as popular as the A500 include:
Although graphics architecture advanced graphics capabilities stood up well against competition from emerging VGA and its extensions, the Amiga no longer commanded the lead it once did.
Amiga custom chips cost more to produce than commodity chips used in PCs, making the A1200 more expensive compared to PC, Amiga than previous models. [Citation needed]
Fewer retailers carried the A1200, especially the United States.
fourth generation of console gaming systems have been cheaper and almost as capable in the game, which was an important use of the A500.
The Amiga 1200 received the bad press of being incompatible with a number of games Amiga 500.
Some industry commentators have a 68020 CPU was too old and too slow to be competitive, and that the machine has been equipped with at least an '030. Complaints were also made on the capabilities of the chipset AGM. Commodore had previously been first worked on a much improved version of the original Amiga chipset, codenamed "AAA", but when that fell behind they had thrown the least improved AGA found on units A1200/A4000/CD32.
Although Commodore never released official figures for sale, Frankfurt Commodore gave a figure of 95,000 systems sold Amiga 1200 in Germany.
Technical information
Processor and RAM
The Motorola A1200 used MC68EC020 CISC CPU (about five times faster than the 68000 processor in the A500). It should be noted that, as the 68000, the 68EC020 had an address space 24-bit, allowing a theoretical maximum of 16MB of memory.
It comes with 2MB of Chip RAM. Chip RAM can not be extended beyond the 2 MB, but an additional 8MB of fast RAM could be added by using the expansion slot door. Adding RAM rapid increase in the rate of stock A1200 by about double (~ 2.26x).
Later, various accelerators featuring 68020, 68030, 68040, 68060 and PowerPC processors were made available by third parties. These accelerators not only faster but also more CPU memory and faster (on the table the more expensive 256 MB 128 MB on two bars), real time clock, IDE and SCSI ports, and video cards .
Graphics and sound
The A1200 comes with third generation chipset, Commodore, the Advanced Graphics Architecture or AGA. As its name implies, the AGA chipset graphics superior skills in comparison with earlier chipsets.
The faster processor A1200 is also allowed for higher rates of sampling for audio playback, but the solid material was not upgraded and remains identical to the 1000 original on the Amiga.
Peripherals and expansion
The A1200 Amiga compatible connectors featured, including two ports DE9M for joysticks, mouse, pen and light, a standard port 25-pin RS-232 and a 25-pin Centronics parallel port. Accordingly, the A1200 is compatible with many existing devices Amigas, such as external disk drives, MIDI interfaces, sound samplers and video digitizers. It was also designed to be able to house a 2.5-inch internal HDD, but it was possible to mount a hard drive inside the 1200 3.5inch if a little brute force was used .
Like the previous 600 on Amiga A1200 included a PCMCIA Type II slot and an internal 44-pin ATA interface to both the most common on laptops. In addition, the A1200 features a 32-bit processor / RAM expansion slot and a feature unique to the A1200, known as the port clock.
The port clock was a vestige of an abandoned design feature for the addition of internal memory and a real time clock. Later, the third-party developers to use in creating a series of developments for the A1200, for example.
