Undefined opcodes for the Intel 8008 CPU

Retrocomputing Asked by Martin Maly on December 31, 2020

What happens when I8008 CPU reads the "undefined" opcode (22h, 2Ah, 32h, 38h, 39h, 3Ah)? Are these opcodes evaluated as a NOP instruction, or lead to some side effects (RESET, etc). How many T cycles those instruction takes?
