Sure, I took a few system photos for you. I'd also taken a couple photos of the Pyro install/motherboard mod for some Twitter posts, so I've gone ahead and uploaded those to Flickr as well: https://www.flickr.com/photos/68824983@N00/

The Pyro came as part of a trade for some SGI gear. The next thing I'd like to get going is a working MO drive. :)

Beautiful. I'd trade you 4 working MO's for a Pyro! :D Thanks for sharing. Does it feel a lot faster than before overall?

It's pretty much night and day difference; faster boot time, quicker window redraws, system responsiveness, etc. I'm really impressed with it!

Also, if you're wondering why my cube has a prototype case/backplane - my original cube chassis was in very poor shape. I bought a freshly repainted prototype cube case (different cooling vents on the bottom, also originally had prototype paint color) and proto backplane from Rob Blessin and transferred all the rest of my old cube's parts (front bezel plate, rear panel, power supply, drive chassis, etc. My old damaged case w/backplane went back to Rob for a trade in credit.

That's also why the front drive bezel looks a little faded and worn compared to the case itself. :)

By prototype back plane do you mean the one that screws in via the 96 pin connector? Example here:



Also next time you open it up can you check the inside of the cube for the foundry marking?

Example:



I'm not quite sure how to completely read the foundry marks yet, but the 8 means 1988. This is from cube #57 for reference. It's seemingly impossible to find these early units without modification so I'm really interested in piecing together a timeline based on serials/foundry marks.

Yes, exactly like that. I opened it up and took some photos of the backplane and foundry marks. I couldn't find a circled number though.

Photos are here: https://www.flickr.com/photos/68824983@N00/?

Edit: Just realized I'd taken a photo of the front bezel foundry mark, and that's not original to the case. The case mark is probably under the backplane.

The foundry marks are behind the backplane. It looks like the screw mounts are missing behind the normal screw positions on the backplane. This dates your case older than the backplane itself (If only by a few months).

Yeah, I didn't notice I was taking photos of the drive bezel foundry marks which is from my original 040 cube.

From what I was told of this case, it was sample used before pre-production and had an early non-NeXT black paint-job applied. It apparently never had a back to go with it, so no serial number, and had a "property of NeXT factory" sticker.

Whenever you get a chance I'd love to see that marking then. That could be the possible baseline for manufacture dates.

Taking out all those slot screws on that backplane is a little more than I want to dive into tonight. :)

If I do wind up taking the backplane out sometime I'll make sure to take photos though.
