Is it possible to use a 040 board as the main board, then use a 030 board for a secondary display, if so any tips would be greatly appreciated!
(I thought, I read somewhere that you need to add some resistors, wiring to the backplate to do this for some reason)

Apparently you can, there's a bit in the NeXT FAQ about running both types of board together in the same cube. http://www.nextcomputers.org/NeXTfiles/Docs/FAQ/Hardware/HW_internal_FAQ.txt section L9.

yep, you can. you have to modify the backplane by cutting some traces and soldering in some jumpers so that each port has the ID 0.
unless I'm horribly mistaken. It looks like its really easy to do. my old Cube was done that way and had 4 boards in it.

sweet! Thanks guys, I will let you know how it works out...
I am making my DB19 Y cables, and will make an extra DB19 to VGA cable for the second card (just for video).
Do I need to load an OS on the second motherboard (so 2 hard drives), or configure or install and software for the second motherboard?
Or will it magically detect the 2nd motherboard and output video to my second display?
Lastly, do I need RAM installed on the 2nd motherboard (as I will only be using it as a display, and if so I assume it wouldn't need much (say 2 or 4MB?)

you can run each board independently of each other oooor, and this would be the best idea, install your OS and drives to the 040 board and have the 030 board netboot off it. then you could run both boards with a full OS for whatever reason or just use the 030 board for distributed processing or have it running apache or whatever.
You will probably want as much ram as possible in the other board. I'm assuming you can run it as a "second display". but you'd still have to boot the whole OS on it and then you could set it up to connect to your 040 board and remotely launch apps. im pretty sure you can do that like with X11 on other unix boxen. That would more or less work like you seem to want. but that is totally out of my league, someone with more knowledge will need to chat with you about that.

It's important to realise that you'd essentially be running two computers together in the same case, the '030 board wouldn't act as a new display card for the '040 board.

As the previous commenter said, you end up with multiple computers in one box. What I used to do was to run my 040 board as my main board, and run my 030 board as a second computer in the box. I didn't have a second monitor hooked up - I just NXHosted any apps on the main system. The 030 board was set to boot via network, and it booted from the 040.

I finally decide to try it myself
I got tow cubes, but one is incomplete, no HD, bo brackets just board and my second is complete working systmem
so, i did modify the backplane. remove the NBIC, replace the battery for a CR 123
my turbo board is OK booting with no problem, but my other board is showing the following message
Exception #2 (0x8) at 0x1006e16
any idea, I test the board before the test and also is showing the same error,
EDIT:
I just realize that both are 040, the one with the problem is at 25 MHz
and the second one (still ok) is at 33mhz 040 turbo
thanks
any ideas?

Does the 040 25MHz board have parity RAM? If so, try some non-parity RAM if you have any. I had a 25MHz 040 Cube with parity memory that would occasionally have the Exception #2 error. If I remember correctly, I swapped in non-parity memory and the problem went away.

Here are some pictures of the 2x2 cube... on flickr. This is a Turbo and a non-Turbo 68040 in the same case with 2 dimension boards. As noted, the very left hand side dimension has low-profile memory on it. You can see how tight it is even now.

That is really cool, gtnicol.
I'm assuming that the turbo 040 board uses both dimensions?

Yes.... the turbo is triple headed. I've been meaning to see if I could get 2 turbos and 2 dimensions in one case, where one uses one dimension board and the other use the other dimension board. I think you'd have to pretty much isolate them though.

cut the backplane up so slots 0,1,2,3 are 0,1/ 0,1 . would probably work fine :) be pretty awesome.

I've been watching this thread with tremendous jealousy. My Cube is a prototype that I upgraded to 040-25, and I don't have a Dimension board. :(
Do you feel my pain? :D

This is an old thread, but here's something I ran across today. An older style backplane that has been modified.

One more... slightly later backplane. Sadly, this one is quite damaged.

Yeah, there seem to have been a number of revisions. The AD/AE are Copyright 1987. I might have it backward... the 1000.00.AA revision is the newer one.
The 1000.00.AA is configured so the motherboard has to be in the far right slot... which allows higher profile memory to be used, but I think this was used for testing chip designs... I have a motherboard (sadly dead) which has one of the chips on a riser, and I believe it came from this cube.

Interesting. I'll bet you could revive that board with a recap. I'm curious to know if there are any differences when it boots up. Thanks for posting.
