The discussion about building your own NBIC (or, finally, your own NeXTBus peripheral cards, which I find very interesting) leaves me wondering how to best experiment with the cards, since it's pretty hard to measure signals when the cards are mounted inside a Cube case.
So, I had the idea of building a minimal setup using a 68040 CPU board and a (homebrew) expansion board standalone on a separate Cube backplane. This, of course, would require a single backplane board (or completely disassembling a Cube, which I would like to avoid).
So, if you happen to have a spare backplane lying around, I would be interested...

I have one how about $25 and $22.50 shipping to Germany
Any version in particular as I have 1989 or 1990 ?

Thanks Rob, that sounds great! I happen to have an extra 68030 board lying around and connecting the Cube backplane to a standard ATX power supply seems easy enough (see Brian Archer's guide at
http://asterontech.com/Asterontech/Next_ATX_Conversion_REV1/).
Do you know if there are any differences between the '89 and '90 backplanes?
I'll send you a separate mail to discuss payment and shipping details.
