The NeXT Cube and the NeXTcube were computers made by NeXT, and aimed at the workstation market. NeXT's hardware was thought to be ahead of its time, but turned out to be a failure. NeXT sold only 50,000 computers in their history.
The NeXT Cube was released in October 1988 and sold for $6,500 with monitor. It was the shape of a big cube and could use some Mac and PC accessories, for example the Apple ADB mouse or a Windows PS/2 mouse.
The NeXT Cube ran a 25 MhZ 68030 processor, and came with a mammoth 8 MB of RAM. It featured a 20 MB hard disk, but intriguingly lacked a floppy drive, foreshadowing what would happen to the iMac ten years later.
The NeXT Cube ran the NeXTSTEP operating system, developed by NeXT. It was bundled with the first version, 1.0, but was capable of running newer versions.
In September 1990, NeXT released an upgraded cube, giving it a confusingly similar name to its predecessor and naming it the NeXTcube. The NeXTcube was much more powerful than the original cube, but came at a considerably higher price of $11,495 including monitor.
The NeXTcube ran a 25 MHz 68040 microprocessor. It came with a much larger hard drive than the NeXT Cube, capable of storing 340 MB, and had 16 MB of RAM. Unlike its predecessor, it featured a floppy drive.
The NeXTcube came with NeXTstep 2.0.
