While it might (I don't know) be possible to make the manufacturing process smaller, you couldn't increase the address space without effectively rewriting the entire ISA. You could use bank switching or an MMU to increase the effective address space (allowing the machine to access more RAM than it can physically address), which was done even back in the day, on pretty much every machine. >you'd be able to compete very well on price for the IoT or other markets. Why do you think that the Z80 and the 6502 (and their derivatives) are still on the market? :-D
