Commodore Amiga 1000
A1000
Developer: Commodore
Launched: July 23, 1985
Discontinued: January 1987
Commodore launched the Commodore Amiga in a grandiose show at the Lincoln Center in New York on July 23, 1985. The machine itself was based upon the earlier Lorraine project. The unit went on sale a few months later, retailing at $1295.00 US dollars.
The company were pressured by Atari to launch the Commodore Amiga ahead of their original schedule . The company had attempted to buy the Amiga technology but had been forced to develop their own 68000 machine based upon off-the-shelf parts. In spite of a shorter development time, the Atari 520ST beat the Commodore Amiga to the market by several months. As a result, Amiga Workbench 1.1 (the Amiga disk based OS) was buggy and prone to crashes.
At the time the Commodore Amiga was far in advance of its competitors: the IBM PC market was using a 16 colour CGA display and the Apple Macintosh was limited to a B/W display. These specifications are taken from the original advertising for the A1000 in the USA. The Atari continued to beat the Amiga in the market for several years, in part, due to Commodore's focus upon the high-end market. It is only when the Amiga 500 was launched that Commodore were able to beat Atari in the home computer market. In 1987 the model number of the Commodore Amiga was combined with the name to officially designate the machine as the Commodore Amiga 1000.

Amiga 500
Developer: Commodore International
Launch date: 1987
In 1987 Commodore released the A500 - a cheaper version of the A1000 - which came in the "distinct" Commodore box. The basic system still used the 68000 processor, 512k ram, and OCS chipset but had got rid of the ZORRO slots in favour of a DMA slot at the side of the machine. The operating system had been upgraded to version 1.3, which included the Amiga Command Line Interface (Shell) allowing the user more functionality. This is the machine that kicked the entire Amiga world into focus and brought more people to the Amiga than has been done since. It was voted "Home Computer of the Year" (36.7) in 1991 by a selection of Greek and Italian publications
There are two different revisions of the A500 motherboard:
Amiga 500P (American) the 'Productivity' edition features 1Mb memory (512k Chip, 512k Fast).
Amiga 500C (American) an improved version that incorporated the new Agnus chip, providing 1Mb Chip RAM (corresponds to the Amiga 2000C).

Developer: Commodore
Launched: March 1987
Discontinued: 1990
Two years after the initial Amiga launch, Commodore released their replacement to the ageing Amiga 1000. The Amiga 2000 developed the 'big box' Amiga market that continued to divide users' until the mid-1990s, and formed the second part of Commodore's plans to diversify the Amiga market into high and low end systems (the low-end A500 had been launched two months previous). Like the Amiga 500, the A2000 was shipped with Kickstart/Workbench 1.2.
The machine offered several advantages over the Amiga 1000 and 500:
* Seven internal expansion slots (5x 100 pin Amiga Zorro II and 2 x 16-bit ISA slots). The ISA slots were disabled by default (only power and ground pins activated), but could be used when a Commodore bridgeboard was installed (a PC-on-a-card). Inactive slots can be used for non intelligent cards like TBCs or fan cards.
* One megabyte memory as standard (expandable to 9MB).
* The CPU could be upgraded through the purchase of a processor card and attaching it to a 86 pin processor slot.

Commodore Amiga 2500
A2500 Unit
Developer: Commodore International
Launch date: 1989
The A2500 systems were based upon the final revisions of the A2000-B motherboard design before the A3000 was released. The first model was released during 1989 and was most popular in the US and Canada, appealing to the high-end user and professional market. There was very little difference from previous revisions of the A2000, the most notable being the addition of processor cards increasing the system speed.
The A2500 range consisted of three specifications:
* The A2500/020 shipped with an A2620 processor card featuring a 68020 and 68881 14 MHz.
* The A2500/030 with an A2630 featuring a 68030 and 68882 25 MHz.
* Of particular interest was the A2500UX. This shipped with AT&T Unix System V Release 4 operating system rather than a version of the AmigaOS, as well as a three button mouse. A tape streamer and Ethernet card were an optional upgrade.

The A1500 was a UK-specific machine derived from the A2000. Both machines use a socketed Motorola 68000 7.14 MHz CPU and were shipped with an empty processor slot. The operating system also remained the same, shipping with Kickstart 1.3. The only difference is that the Amiga 1500 shipped with two floppy drives, 1MB Chip RAM and a new nameplate.
CheckMate 1500 upgrade
The exact reason why Commodore chose to release such a limited machine has remained a mystery for years. Many suggest CBM UK released it to "kill" an A500 desktop conversion unit sold by Checkmate Digital that was also called the A1500. Commodore always had a questionable business sense. By releasing a competitor to another company they were almost certainly attempting to drive potential Amiga suppliers out-of-business, as well as spending large amounts of money on a system that added little to the Amiga market. Alternatively, Commodore may have had a lot of internal floppy drives they wanted to use.
After Commodore released the A1500, First Computers in Leeds released an unofficial upgraded version called the 1500+, an ECS version of the A1500 that included the 2.04 Kickstart ROM. There was also a later version dubbed the 1500Deluxe that added an 1.3/2.04 ROM switcher and RAM expansion. Silica released a similar system called the 2000Plus that dropped the RAM expansion, only including the ROM switcher.
Commodore Amiga 3000
A3000 Desktop
Developer: Commodore International
Launch date: April 24th, 1990
The A3000 is a powerhouse in comparison to previous Amiga, it was sold as a high-end graphics workstation. For a time it was used by W Industries as the basis of their highly acclaimed Virtuality machines. At the heart of the A3000 was the powerful 68030 (described in ST/Amiga Format as a 'mainframe on a chip'). In addition the A3000 was the first Amiga to feature the new Kickstart 2 upgrade and Zorro III slots.
To emphasis the A3000s capabilities as a high-end workstation, two operating systems were included:
The first was the newly released Kickstart/Workbench 2. This was unusual by the fact that Kickstart was stored on the hard disk rather than in ROM. This was similar to the A1000 that required Kickstart to be loaded from floppy disk before anything else could be done.
The second OS to be included with the A3000 was the Unix System (SVR4) V operating system. This allowed the use of the Unix graphical interface, X Windows and Open Look. It also came with standard networking capabilities (probably a first for Commodore), such as TCP/IP, NFS and RFS for networking between different operating systems. In a bizarre twist, the Unix OS was sold on a magnetic tape rather than floppy disk.

Commodore Amiga 3000T
Amiga 3000T
Developer: Commodore International
Launch date: October 1991
In October 1991, Commodore introduced the A3000T, a tower version of their popular A3000 machine. The A3000T uses a 25Mhz 68030 processor, with a 68882 maths-coprocessor, as well as 2MB of 32-bit ram as standard, expandable up to 18MB actually on the motherboard. As it was released before SIMMs became a standard it uses Zip ram, a slower alternative. If you want an SIMM adapter, you will need to buy a device from mail order. The workstation was aimed at the professional multimedia market, as reflected in the price of the machine- $4498 for an A3000T with a 100MB SCSI hard drive, or $4998 for the 200MB version. It also came with key switch on the case. These are used in the commercial market to disable a machine when it is not being used, locking the mouse and keyboard.
The professional image of the machine was reinforced by David Archembault, former director of Business markets at CBM, stating,
It is a multimedia workstation combines all the capabilities of the A3000 with an unprecedented level of expandability and power.
This was shown through the HUGE array of drive bays available- two 3.5 inch drives, one 5.25 inch mounted horizontally; and two 5.25-inch half height drives mounted vertically. Behind these drives there is space for two more internal 5.25 drives, or any other expansion. The Workstations expansion slot includes up to 5 Zorro III cards, 4 Bridgeboard PC cards for use with emulation, a video slot for internal video and a processor slot for a 68040/060 accelerator card.

Commodore Amiga 3000T
Amiga 3000T
Developer: Commodore International
Launch date: October 1991
In October 1991, Commodore introduced the A3000T, a tower version of their popular A3000 machine. The A3000T uses a 25Mhz 68030 processor, with a 68882 maths-coprocessor, as well as 2MB of 32-bit ram as standard, expandable up to 18MB actually on the motherboard. As it was released before SIMMs became a standard it uses Zip ram, a slower alternative. If you want an SIMM adapter, you will need to buy a device from mail order. The workstation was aimed at the professional multimedia market, as reflected in the price of the machine- $4498 for an A3000T with a 100MB SCSI hard drive, or $4998 for the 200MB version. It also came with key switch on the case. These are used in the commercial market to disable a machine when it is not being used, locking the mouse and keyboard.
The professional image of the machine was reinforced by David Archembault, former director of Business markets at CBM, stating,
It is a multimedia workstation combines all the capabilities of the A3000 with an unprecedented level of expandability and power.
This was shown through the HUGE array of drive bays available- two 3.5 inch drives, one 5.25 inch mounted horizontally; and two 5.25-inch half height drives mounted vertically. Behind these drives there is space for two more internal 5.25 drives, or any other expansion. The Workstations expansion slot includes up to 5 Zorro III cards, 4 Bridgeboard PC cards for use with emulation, a video slot for internal video and a processor slot for a 68040/060 accelerator card.
