HP 5061-3001 (1975) While Intel marketed the i4004, HP developed a full blown 16bit CPU for the HP 9825 computer. It was implemented with 4 NMOS dies on a ceramic module, the BPC (Binary Processor Chip), EMC (Extended Math Chip), IOC (I/O chip) and AEC (Extended Address Chip). pic.twitter.com/jqyoElbQKm
