Cache has been around for quite some time - the "first" implementation was in either a late model S/360 or early S/370 (I can't remember, but around 1970 anyway). Originally it was to be called the "muffer" - memory buffer. Look in *IBMs 360 and Early 370 Systems* from MIT press (you have a copy, RIGHT?).

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.
