Gould made a number of machines which had a two way
set associative
cache. The Gould 9000, 8600, and 67 all had this style of cache memory.
The 9000 also had an expandable cache which they called shadow memory
that worked by overlaying a block of DRAM.
I don't know for sure the dates of these machines, but I think only the
8600 was pre 83, possibly mid to late 82.
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..
