Time penalty for non-alignment on VAX/780

[Paul Campbell]

No .... the Vax does not (necessarily) read data from its cache 64 bits at a
time. What it does is fetch 64bits into cache from memory when a cache miss
occurs (the SBI is 64 bits wide). This is a good idea for several reasons, 
for instruction lookahead, data lookahead, and it makes the cache design a 
little easier not having to compare as many address lines.
