That says KA46, as does NetBSD.

I've been 99% sure that I have a /60 for a few months now, but I've
always been suspicious that the case is non-original.

I'm not sure what these two results mean :-)

Ok, good :-)

That bit of information was very helpful, thanks!

On the front of case the little sticker says 4000/90.  On the back it
has the following information (reading from my scribbled note since the
box is at home, so 5 might really be S, etc):

CPU KA46
ZZF HF000053
Series BA46A
Model VS46K-EA
SN AB344101EKJ

Hmmm ... is the SN on this sticker what the DECUS Hobbyist groups refer
to as the "CPU Serial Number"?

(Yeah, I could desperately use some more RAM. Actually, a fully stuffed
 4000/90 would be nice, but I got this box for a *slurpee* so I'm not
 complaining).

So everything except the front case sticker claims that it's a KA46.
Is there any chance that the case is non-original? Or is it more likely
that since the 90 and the 60 used the same case design that the sticker
on the front is just a generic sticker?

Great info! I do indeed hear only the 3 short notes.
