This is a bit late, but I believe the cache sizes above are wrong. As
far as I'm aware, the '51 has 4k i-cache + 2k d-cache. The '52 has 8k
i-cache + 2k d-cache. The '81 I'm not so sure about, but I suspect it's
16k i-cache + 8k d-cache, not as indicated above. Anyone have a book
with the '81 spec?

I suspect there's not much of a price difference between the '51 and
the '52 either - perhaps we'd do well by going for the '52 when the
time comes? As Steve mentioned, we don't really have to worry about
this yet anyhow...
