The early PDPs used discrete CPUs, so they'd probably be the closest examples, the 12-bit PDP-5 is the smallest those CPUs went though, which isn't hideously more complex than a 8-bit CPU.
- anyfoo 3y agoI thought about CPUs with either discrete transistors, or with e.g. 74xx ICs. But the former intuitively seemed too big to me (because I was assuming they use large transistor packages instead of SMT), and the latter too small (because a single 74xx logic chip can pack a lot of transistors). So this “hybrid” of having SMT components in a can by IBM seemed close. Happy to learn more!
