| Dec 25, 2020 at 7:16 | comment | added | Jerry Coffin | @another-dave: difficulty in finding process node information for chips this old stems primarily from one fairly simple fact: the idea of a process node didn't come into most people's thinking until there were a few generations to start showing a trend. In addition, at the time density depended quite a bit on circuit topology (NMOS vs PMOS vs.HMOS, etc.) Process technology only became all-important after everybody settled on CMOS for nearly everything (which was later than the chips being discussed here). | |
