Four controllers: AGC, HP2116, P82, HP9825 [Full page comparisons] — [index].

Apollo AGC

HP-2116

P82

HP-9825

Design of all four is optimized towards control of equipment through an input/output (I/O) section with prioritized interrupt capabilities and dedicated instructions for a real-time operating environment. [The HP2116 however, was a general purpose computer and so quickly developed into other areas.]
