That's rather generous, isn't it? The KA820 is, IIRC, virtually the
same speed as the uVAX-II (0.95 VUPS). I didn't think the KA825 was
twice as fast. I was thinking 35%-50% faster at best.

Ah well... I'd be happy with *one* KA825, let alone two. I doubt I'd
ever need three. I could always test my multiprocessor mods to the
COMBOARD-BI driver (which were only tested in practice by our beta
customers, since we never had a multiprocessor VAX during development).
