The Dutch computer ARMAC had a nice optimization, a

Under software control a given track would be copied to that buffer
(in some sort of RAM -- core?) and then references to those addresses
would be satisfied from the buffer. You could think of that as a very
early cache. That was the machine on which Dijkstra first implemented
the spanning tree algorithm (as a demo program for an exhibition).
Spanning tree? Really? Surely you mean Shortest Path First?
