V8.4-2L2 has a minor change or two beyond being rebuilt for EV6. It's 
not exactly the same as V8.4-2L1. V8.4-2L2 also incurs the VSI new-user 
tax.

As for Alpha emulator performance, try some other emulators. AXPbox is 
one that's been discussed around here. An emulator with JIT support 
will likely be faster.

Scrounge (buy) an AlphaStation DS15, if you're in this for the long 
haul. DS15 is easier to work with than is the AlphaStation XP1000. And 
less fragile. And newer. And faster.
