> Alpha was the first 64-bit platform NT ran on

Interestingly enough, NT used the Alpha as a 32 bit processor[0]. Although NT on Alpha was used to port Windows to 64 bits in lieu of using the (very slow) Itanium simulator[1].

Actually, this was discussed on HN earlier[2], and I believe you wrote an article for The Register[3] about it :)

Yep, that was me and what I had in mind.

Shipping versions of NT on Alpha were all 32-bit, yes, but there was an internal unreleased 64-bit build.
