2.25.4 Intel RapidCAD CPU

Intel i80386 CPU with FPU (Floating Point Unit) (same implementation as Intel i80486DX CPU).

The Intel RapidCAD CPU consists of a set of 2 chips. The Intel RapidCAD-1 (132 pin PGA) contains the Intel i80386 CPU with FPU. The Intel RapidCAD-2 (68 pin PGA) fits in the Intel i80387DX NPX socket and contains a PLA for the FERR signal generation.

Intel i80386DX CPU / Intel i80387DX NPX pin compatible.
