The downside of running a 32-bit version of virtually any AXP simulator
is that it is bound to be 2-3 times slower than 64-bit version, due to
(a) simulation of AXP 64-bit operations on top of 32-bit host operations,
(b) indirect access to guest memory when it is sized above 2 GB or so
assuming such an access is implemented at all.
The only exception to (a) would be a 64-bit simulator squeezed into 32-bit
environment running on 64-bit machine, but this is hardly worth the effort.

Subject: [Simh] Is Alpha AXP in SIMH's future?
Is an Alpha machine capable of running OpenVMS in SIMH's future? I know
there are several Alpha emulators for Linux and Windows but I really like
SIMH since it runs on pretty much any UNIX-like OS and doesn't depend on
having a 64-bit Linux installed.
Thank you for SIMH.
