Modcomp had by the mid eighties in the Classic32's a 64kb four-way set of
associative cache memory, and 16 sets of independent mapping register
cache. This was carried through to the TriD series 9230-60's with some
expansions. I've forgotten what the earlier 7800's series had, and dont
have manuals here to check, but I think the Classic 7870's had a fair
amount of cache..
