Early chips had every transistor drawn by hand. Federico Faggin, designer of the popular Z80 processor (1976), spent three weeks drawing transistors but the last few transistors wouldn't fit so he had to erase everything and start over. The result was dense and chaotic. 3/17

@kenshirriff is this thread something that will be continuing at a later date? Or maybe a federation issue - I’m only seeing up to 3/17

@kenshirriff weird. Will see if I can get at it if I’m not logged in, or maybe just on the web. Thanks
