Ah. I wonder where it came from originally? That looks like a relatively 'new' one; the older KA10's had black panels. And it's odd (to me, at least) to see TU56's on a KA10. I wonder how many KA10's are left in the world? I have this vague memory that MIT-AI might have gone to Sweden, but I also have a memory that that was the plan, but some how it didn't happen? Noel
