< ::It was Intel's competitors - notably Motorola and especially MOS < ::Technology - who were responsible for driving microprocessor CPU cost < ::to the hundred-dollar-level and below.

Tim is right as is was MOS Tech. that lobbed the biggest shot by offering the 6502 for a mere $20 (single unit price!) at one of the computer shows. < I agree with this. The 6502 architecture and the 6800/68000 series did m Where did zilog fit in... they certainly improved on the 8080, they did it cheaper and had a design that was easier to use too. Forced intel to emphasize the 8085 that didn't extend the instructionset of the 8080 any significant amount. < to advance low-cost computing than anything Intel did. Intel seemed perf < satisfied to stay in the high-end market until relatively recently. I strongly disagree. The following were Intel chips aimed at low to mid end applications/markets. 8048/9 series the 8088 and 80188 parts (8bit bus lower cost to use design with) 8051 series That may not be the total list either. The market that intel couldn't or didn't care to be in was the $1 single chip microprocessor market where TMS1000, COPS, uCOM4 and other 4bitters can and did have a distinct presence. Allison
