HP Calculator Opcode Map
Posted by George Weigt on 14 Dec 2000, 5:48 p.m.
HP Calculator Opcode Map
To find the opcode for a particular instruction, or-together
the coordinate bit strings, treating xxxx as 0000.
This map was created with the help of
Eric Smith's
assembler and may be used to help understand the
HP-45 simulator.
