Motorola 68040.The Motorola 68040
makes NeXT computers capable of
processing at 15MIPS and 2 MFLOPS.
Motorola 56001 Digital Signal
Processor. All NeXT computers come
with a DSP, making them capable of
generating music, speech, and CD-
quality sound. The DSP lets the com-
puter handle large matrix calculations
with extreme speed.
 |
2.88 MB floppy disk drive. This drive
gives you the ability to store twice as
much as today's standard drives. It also
reads from and writes to DOS-formatted
disks, letting you easily transfer data to
and from other computers.
Ethernet. Every NeXT computer fea-
tures both thin and twisted-pair Ethernet
built in, making it a snap to connect a
NeXT computer to an Ethernet network. |
Serial and SCSI ports.NeXT computers
can use a variety of external devices.
Every NeXT computer features a SCSI
port and two serial ports that let you con-
nect to scanners, fax modems, external
disk drives, and tape backup units.
MegaPixel Display. The NeXT mono-
chrome and color MegaPixel Displays are
some of the clearest around. They have
plenty of space on screen, so you can
view multiple applications at once.
But they don't take up a lot of space on
your desk.
