Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Burroughs large systems instruction sets include the set of valid operations for the Burroughs B5000, B5500, and B5700 computers and the set of valid operations for the Burroughs B6500 and later Burroughs large systems including the current Unisys Clearpath/MCP systems. These unique machines have a distinctive design and instruction set. Each word of data is associated with a type, and the effect of an operation on that word can depend on the type. Further, the machines are stack based to the point that they had no user-addressable registers. As you would expect from the description of the run-time data structures used in these systems, Burroughs large systems also have an interesting instruction set. There are less than 200 operators, all of which fit into 8-bit "syllables." Many of these operators are polymorphic depending on the kind of data being acted on as given by the tag.
