Introductory price : US$10,000 ($18,051 in 2015)
Discontinued : 1993
Operating system : NeXTSTEP, OPENSTEP, NetBSD (limited
support)
CPU : Motorola 68040 @ 25 MHz, 56001 digital signal
processor (DSP)

this cube soon)

I only have a
Cube, a CD-ROM, an installer CD , a floppy disk, 4 books.
I missed the Display and keyboard and mouse to get it
work.
top left is "Setup and Tutorials"
top right is "The NeXTSTEP Decision"
bottom left is "NeXTSTEP USER INTERFACE GUIDELINES"
bottom right is "NEXTSTEP"
If I can get the cube works, I should be able to have sufficient material and get a try on this "new" operation system other than System 6 or 7 on the Motorola 68k cpu.

After opened the
back panel, the cube have 4 slots. The first from right
hand side and the first from left hand side is empty. The
second from right hand side is the CPU logic board. The
second from left is display board.
Intel i860
using in this display board.
4 RAM slots have been used up. Need to figure out how many MB has been installed. Seems need 4 banks as a set.
A Bt463 chip using on left bottom side. Need to figure out what it is soon.
Another Nubus slot on the middle right hand side ?
CPU
marked as XC68040RC25 on the logic board. So, it should be
a Motorola 68040 cpu with 25MHz.
4 RAM slots have been used up. Need to figure out how many MB has been installed. Seems need 4 banks as a set. Total have 16 slots.
A Bt463 chip using on left bottom side. Need to figure out what it is soon.
Another RAM slot on the middle right hand side ?
The PRAM
battery is Panasonic 3V Lithium BR-2/3A.
The ROM states : NeXT Computer Inc @ 1991 Rev 2.4 v65.
The whole board is so clean and seems to be seldom used as all, in excellent condition !! Need to find a work-a-round method to get it have display.
The chip next to it is Motorola XSP5600IRC20.
This special
19 pin socket need to connect to a triangular box and then
connect back to the keyboard. So, it should include some
kind of pins of keyboard and mouse. I need to figure out
too.
I thought it was a video display port according to the graphic markings.
However, when I bring Macintosh PowerPC 6100 or 9600 or Color Classic or Quadra 950 display adaptor out, it is not the same pins layout.
On the left
hand side of the Cube back side, I found this another
strange socket like the photo. It contains 2 bigger holes
on top and 1 bigger hole on bottom.
This is something I have no idea what the socket is ?
May be it is specially for NeXT monitor ? I would like to
find some adaptor to convert the signal to a normal CRT or
LCD display if possible.
Thanks to Pozdrawiam Grzesiek of his information and
provided link :
"This jack is for connecting a monitor. All Sun
Microsystem servers and stations that had an additional
better graphics card (Creator 3D) had this output. The
socket is called 13W3. You can buy an adapter or the
entire cable."
