Yes, a 610 is indeed what Ihave. That would explain why it didn't match
the machiens you were talking about. ;)  And, yes, I believe that it is
a 68LC040.

I wanted to run some BSD on some Mac. That's what I had to start with. I
had a couple of spare 610s but not much else. I could have used an LC I
suppose, but I thought it'd be too slow. Anyway, it was an experiment.

I now have a "ci" or something like that, and I may take the drive out
of the 610 and put it in that. I was hoping that the disk that my
Mac-weenie friend gave me had A/UX on it, but it only had A/UX upgrades.
Next best thing is NetBSD I guess.

If you happened to have a real 68040, it appears that I could put it to
good use... ;)
