The National IMP-8 is a family of multi-chip 8-bit bit-slice microprocessor developed by National semiconductor and introduced in 1974. The chips were made using PMOS technology. Units could be combined to implement systems with 8 to 32-bit words. The IMP-8 was designed using 2 IMP-4 4-bit bit-slice RALUs and an 8-bit control unit.
