It may surprise, but ALL Cray-1 machines, does not have MICROprocessors at all - just digital logic low scale integration.
And nearly all "Big" computers before era of mini-computers, also does not have MICROprocessors, their CPU consists of whole board of chips or even more than one board.
Imagine, one of the first commercial computers with MICROprocessor chip, was microVAX II, appears nearly decade later than 8086.
- leetbulb 4y agoA CPU, whether its implementation is a microprocessor or a board of chips, is very different from a game implemented only using discrete components. It is crazy though to imagine supercomputers implemented without microchips, not to mention vacuum tubes, hell, wood and brass.
- simne 4y agoThis is just matter of correct naming. - MICROprocessor, ideally is a one semiconductor die, which integrates all cpu parts. Unfortunately, now silicon approaching limits, so to make things cost effective, have to do compromises, use chiplets, imposers, but this is very far from universal components on board.
