There was also a great instuction called "movem.l" which moved multiple registers at once to almost anywhere (and vice-versa). It was used mainly to allocate stack frames, but could be creatively used to move stuff from place to place REAL fast.
Three whole instructions worth of cache.
"Wha...?" you might say? Tha' heck good is that? The point was that the 3-instruction cache could cache tight loops, like the kind you would use for mem-to-mem copies, which is a terribly common thing to do. I put one in my Amiga 1000 (geez, did I hack that thing...) and got about a 10% overall system performance increase.
It was neat! More lovely details here: http://www.memphisamigagroup.net/diskmags/198803/68010-kit/M...
