As to your first point, I suppose I kind of assumed the readers here were familiar with MOS Technology and their work in integrating DRAM onto the same die as a processor, along with advances in ROM manufacture, and the general push to system-on-a-chip integration. To be clear, Chuck Peddle also helped design chips like the RRIOT (1 KB of ROM, 64 bytes of RAM, a parallel IO port and a timer). A machine like the KIM-1 (also of Peddle's design) would not have been possible without the RRIOT chip, anymore than without the 6502. I just find it skewed that we all focus on the microprocessor he designed, when a chip like the RRIOT was just as important. Microprocessors are pretty nifty indeed, but they'd be useless without IO and memory just as cheap and small to go with them.
