Early single-chip silicon CPUs like Zilog Z80 or MOS 6502 did not have a multiply instuction at all. Was it because the technology did not exist at the time to implement it, was it too expensive or simply there was no need for such instruction set (similar to FPUs for Amiga power users, majority of people could and did go by without it)?
