Yes, actually. They're looking to do a simulation like the visual 6502
(at visual6502.org), which should present some interesting challenges
(the analog portion will probably be a lot harder to simulate).
I wonder when they're going to do the VIC II. :)
And lots
of cool die shots of various revisions here:

Good heavens. Are those guys reverse-engineering the whole chip?? Some amazing shots
there, and interesting documentation! Someone may be intending to make new hardware, as
well; there are quite
a few hardware SID synths (HardSID, for example) that make use of actual
pulls or NOS, but both pulls and NOS are getting quite hard to come by
now (especially of the 6581). Sounds like an interesting project to me;
I think intentionally making a crappy filter is better left to discrete
transistors than an IC.

Political correctness is a doctrine, fostered by a delusional, illogical
minority, and rabidly promoted by an unscrupulous mainstream media, which
holds forth the proposition that it is entirely possible to pick up a turd
by the clean end.
