Debugging a dimension

I'll post some photos later on today, but here are some of the differences I've seen:

1) One of the larger chips will have, or not have a gold top.
2) Memory sockets will have steel retainers or plastic.
3) One particular chip towards the center of the board is usually yellow.
   I have one which is black, and which has a patch wire across the chip.

I've been trying to figure out what these differences mean in terms of production runs, etc.

I posted pics of my NeXTcube on Flickr a while ago.  There are pics of both my Dimensions

Take a look here:

Right, so that looks like a "normal" board. I have one where the yellow chip in the top-middle is replaced with a black chip+patch, and where the big chip in the middle right has a gold top.

I'll post photos tonight.

Does anyone knows what it means if the LED stay on, no blinking ?
