NeXT released a second generation of workstations in 1990. The new range includes a revised NeXT Computer, renamed the NeXTcube, and the NeXTstation, nicknamed "the slab" for its form-factor of a low-rise box. Jobs explicitly ensured that NeXT staff did not use the nickname "pizza box", so that the NeXT machines would not be compared to competing Sun workstations which already had that nickname. The magneto-optical drive was replaced with a 2.88 MB floppy drive but 2.88 MB floppy disks were expensive and the technology failed to supplant the 1.44 MB floppy. Realizing this, NeXT utilized the CD-ROM drive, which eventually became an industry standard for storage. Color graphics were available on the NeXTstation Color and on the NeXTdimension graphics processor hardware for the NeXTcube. The new computers were cheaper and faster than their predecessors, with the new Motorola 68040 processor.
