The serial code on my Turbo Mono slabs CPU is XC68040RC33E. My Color slab is XC68040RC25.
According to cpu-world.com, the prefix, XC means "Pilot production device".
Here is their ID Chart.

Any of you have MC68040xxxxx serials on your CPUs? the MC stands for "Fully qualified parts".
I'm just curious to know if NeXT used XC marked 040s for most of their machines. Were the 040s really new when they stuck them in NeXT's computers? I dunno much about the 68k history in that respect.
What about you with 030s, what are the serials on those?
I noticed this today when I took my NeXT apart. Just thought it was interesting :) I hadn't read anything with regard to the cpu revisions used in the machines.

Most of the NeXT hardware I've seen had the XC prefix on the 040 CPU's. A few years ago I just missed getting a cube that NeXT let out the door with a 68040 sample CPU.
Notice that it has no XC or MC prefix and the word "Sample" has been crossed out with a black marker. It's interesting how NeXT let prototype stuff make it into production.

@helf:
If I recall correctly there was also another designation for prototypes, I think "PC", as in PC68040, although nothing is mentioned in http://en.wikipedia.org/wiki/Motorola_68040
All my NeXTs have the XC designation, although I have some MC parts, but not in NeXT machines.
@Nitro:
That's an interesting story/photo there! Too bad it didn't fall on your lap :( Who got it? Someone from these forums?
