QuoteI don't know about the internals... Although I'd guess they'd be ok, mostly
I had a lead for a 030 board for the price of shipping but he refused to deal with me because I didn't like his hack and whack job he did when he modded a cube to hold a pc.

...Anyways, I don't want to derail this thread. You got a great system. :wink:

ugh, I cringed everytime I read "hacksaw" and "dremel"...

Also...

"Actually... the case itself is untouched and unbutchered in any way... all 5 sides except for the back are completley stock. The inside had several raised screw mounts which were cut and ground off but as for the appearance of the case it is bone stock with no modifications."

wtf? Cutting up the inside *is* butchering the 'case' :P The case isnt just the outside :)
After an apparent 15ish year hiatus... I'm baaaaack! :D (12/12/2023)

Heh, it's definitely butchering! Did you see the back side? Bastardized completely! :(

@pentium: well, you had to speak your mind, no? :-) Anyways, worry not, your cube will come some day soon! :-)

So can some of the hardware gurus around here identify this weird component (yellow piece in the photo):

Also what are these chips, and what are they used for:

EDIT: based on this photo (http://www.channelu.com/NeXT/Black/68030/index.html), I can answer the last two questions:

NBIC = NeXT Bus IC, controls the bus

Custom LSI 1&2 for Optical Drive control and 12channel DMA I/O control

The question still stands for 1 :-)

If you follow the link below, you'll see some items that came with this uber-rare cube. Not all are as rare, but some are (Correction: the NeXT RISC Workstation is about as rare as this cube!). Right now it's just a small preview/sample:

Cubes:
ADA... are 33mhz 040s
AAX... are 25mhz 040s
AAG... are 25mhz 030s

Stations:
ABB... are 25mhz (early) or 33mhz (later) 040 mono
ABC... are 25mhz (early) or 33mhz (later) 040 color

Interesting....  My Cube is AAK0018445 and its a 33mhz 040.  

It came out of the factory so I assume it was probably updated whenever new stuff was available.  It was, apparently, on an internal network called Cassiopeia (IIRC).  Other than some huge music files everything of interest was wiped from the HD before I got it.

The serial numbers you were quoting were for mainboards, not the case/machine serial numbers...

Did you poke around the "empty" disk space before installing stuff over it? Never know what's hidden there... :)

jheis

Yeah. I poked around as much as I could, but it was about 13 or 14  years ago & I didn't really know what I was doing.  I think I've still got the original 450 MB drive around somewhere.  Maybe I'll dig it out & take another look, but I was more interested in filling up the "empty" space than retaining what was there.   :wink:

Heh, I hear ya. Then again, it might be in vain, because those persons surely knew the need to wipe everything of real value and mystique :)

Quote from: "da9000"I promised the nextcomputers.org folks I'd put some photos up, so here they are!

Please realize that I'm not a photographer, I had almost non-existent lighting and a rather simplistic camera without a tripod :(  Aka: some photos are blurry and dark (I swear they looked brighter in the LCD :))

Enjoy and feel free to answer some of the questions posed, about the chips and things :)

EDIT: now that I know about BBcode, let's put up a sample photo or two:

Thanks for sharing the photos.  What a great, rare machine and a great find.  :D
