Aren't OS's being written and tested on the IA-64 and AMD 64 at this moment?



64-bit OS's have been around for a long time, but not in the mainstream.
DEC alias Digital alias Compaq alias HP created the Alpha back in the
early 90s.  That has had a full 64-bit address space for years.


Yes, and the MIPS R10000 was the first shipping 64-bit microprocessor.



I don't think that's right.  The first R10K I evaluated to buy was a brand
new SGI Origin 200, and I was comparing it against a second-hand Digital
AlphaServer 2100.

According to Wikipedia, MIPS R10000 was released in 1995, the Alpha
21064 in 1992, and the 21164 also in 1995.


Sorry for picking the wrong MIPS implementation.  The R4000 was the
first 64-bit micro.  It was introduced in October, 1991.

I show the Alpha 21064 shipping in November, 1992.

Those are memories I haven't revisited for a decade...  ;-)
