In 1992 Commodore launched the most advanced Amiga yet. The A4000 used the AGA chipset to allow it to show 256,000 colours on screen from a palette of 16.8 million, as well as the new Workbench 3 that introduced the concept of among other things, datatypes. Several variants were available, all fitted with 6MB RAM, 1.76mb High-Density disk drive and a hard drive as standard. The A4000 was release in two different models the A4000/30 & A4000/40.
