Yes, but when I look at:

it doesn't look like

http://www.mos6502.com/images/C64Internal/C64i_large.jpg

either. And...

... IMHO all the narrow boards, including the above 250469 do the same, and sometimes poorly. They are emulating the real C64 with their "improperly" sounding SID and "sparking" CMOS VIC (plus others, less outside noticeable differences), trying poorly to emulate the real 6581/6569 respectively.

Yes, "ultimate" is a big step further in terms of "reimplementation" (as opposed to "emulation"), but - hey - wouldn't it be the natural way to go further if - say - CBM lived and kept selling C64s today?

Hmm... I guess they wouldn't be able to afford to invest so much of the R&D as Gideon did so maybe no, in fact :-))
