< How many instructions? I believe the Pentium has on the order of 80, not < sure. More like 100+, not counting all the addressing modes. the instuction set for the 8086 is many times larger than the PDP-8. The PDP-8 instuction set is 47 (most all variations included), it's very minimal. < They weren't networked at all? I mean, there weren't instances of < connecting two machines with cables? Actually there was DECnet-8! Dual processor machines were not uncommon. but they were not networked like you would current machines. It was not the mindset of that era and generally not required.
