While working on
this (
http://www.nextcomputers.org/forums/viewtopic.php?t=1090) problem having to do with powerup and the real-time clock chip, I went to my spare board. And now I've discovered why it became my spare: twisted pair doesn't work. Hopefully, the thin wire does and I can get it on the net again.
But clearly the hardware is entering a period where it's going to take some initiative and effort to keep running. Identifying other gear that can source parts. Keeping broken NeXT hardware around for the same purposes. Gathering docs for obsolete parts and diagnostic procedures for analyzing problems.
And one thing I'd like to get is an extender board to raise a nextbus board off the bus and hanging out the back where it can be probed. Someone else asked about this, I think, and I wondered if it exists.

Unfortunately it does not exist. I verified it thru an ex-NeXT engineer.

Oh, well. Perhaps I should just pick up a caseless cube...
They do exist but the problem will be finding one.

Do you have any more details? Was this a third-party card perhaps? Or a prototype? Post pictures if you have one.
The design/manufacturing engineer I know who used to work at NeXT explained to me that these type of extender cards used to screw up the timing of the Nextbus so they were never used/produced. Instead, they used a backplane with a power supply harness for DVT (device verification testing) to test motherboards outside the case.

If anyone's after a caseless cube, I have one I could sell. I acquired it at an e-bay auction in a package deal including all sorts of other goodies I wanted to have. But the cube itself is a bit expensive to ship from the USA to Europe now that USPS no longer does surface mail, so it's still on the other side of the pond.
I think it's a reasonably famous one - having featured in a Digg article etc.
digg article? explain. :)

Well, I'm in the other Cambridge. Describe the cube, I may be interested...
68030 25MHz cube, without case (the case was apparently damaged, but apparently other than that, the cube works perfectly). The cube is mentioned here:

I have heard of this basement.
Reminds me of that guy in europe who has 15+ TAM's sitting around.
