There are a few, like MIPS R4000 in 1991, which was used by SGI, then there's Sun's SPARC, HP's PA-RISC..
And if you start looking at the supercomputers like Cray-1 and others, you find that 64-bit architecture has been in use for quite a while:P
http://en.wikipedia.org/wiki/64-bit Wiki's 64-bit article has some info on what was and what is currently. Might be complete, might not be complete. Can't see much sources on that page, so it might not be accurate.
The DVD has been for sale from August. The order form is on the main site. One thing about the DVD: It's in PAL format. IIRC, they were making an NTSC version of the DVD. So all of you who don't own a DVD-player which can play PAL DVDs, I recommend you wait for the NTSC version.
