The first release of DEC OSF/1 (aka Tin aka 1.0) was 32 bit but then it
ran on DEC's MIPS based systems so that isn't surprising.

The first release of DEC OSF/1 for Alpha (aka Silver aka 2.0) was a 
64 bit O/S (aside from lingering 32 bit bugs).  It was not a 32 bit

VMS (until 7.0) was limited to 32 bit addressing.
