Released in June 1990, this machine contained numerous improvements. For the first time a full 32-bit processor, the 68030, was used and it was easy to upgrade with a special processor board. As standard it was delivered at 16 or 25 MHz.
Extensions could be made with the new and much faster 32-bit Zorro III bus.
A variant is the A3000UX where Commodore had an agreement with AT&T to supply Unix System V (release 4). There is also a variant in a tower, the A3000T.
The mainboard contains a DMA SCSI controller and a VGA connection in addition to the standard RGB connection. This is the only Amiga with these 2 extras on board.
There has been a prototype successor, the A3000 +. This would contain the new chipset. However, it was not yet ready for production and the project was scrapped, to be replaced with the Amiga 4000 in 1992.
Many believe that this is the best Amiga. The successor was produced cheaper, which meant that quality was compromised. Not many were sold either, as the Amiga 2000 was still often satisfactory and the announcement of a new chipset made people wait.
