Matt, list:

perhaps we in the land of abundant and cheap EV56 and above systems can help
those few who are still using the lower-numbered CPU systems upgrade?  You cn
mail a 164 LX mobo/cpu care package anywhere in the world fairly cheaply.

I've done similar in the past.  It's nicw if the recipient agrees topay the

just a thought - we need all the hands and heads we can get to keep the Alpha
architecture in play.

> Hi,
> I'd like to drop support for non-BWX Alphas (EV4 and original EV5)
> from X. These machines can't load/store to single bytes and require
> special sparse memory mappings.
> The code required to select which functions (sparse, dense) is
> convoluted, adds an extra layer of indirection, probably gets close 
> to zero usage, and even less testing.
> Does anyone use X on EV4 or EV5 (not EV56, EV56 has BWX)?
