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.
