эт явно от варианта зависитСообщение от BarsMonster
например это фото ну ОЧЕНЬ похоже

судя по фотке выше - таки клон
и есть еще много аргументов
Intel - April 1974 Intel releases its 2 MHz 8080 chip
USSR - 1978
в точности совпадают выводы
в точности совпадает это странное питание, это странное тактирование
набор из "комплекта" - ну сильно совпадает
да и у интела четко видны корни 4004 -> 8008 -> 8080 ->
а у 580 один как перст в поле ....
и кстати
March 1976 -> Intel 8085
July 1976 -> Zilog releases the z80 2.5
May/Jun 1978 -> Intel 8086
ну и еще есть паралельные факты, типа
"M.Shima [21] was the 8080 project manager under Faggin. My specification used all 256 operation codes, and 12th from the bottom of my list was an obscure instruction (XTHL) for exchanging the top of stack with the HL register pair. This instruction required five memory cycles to execute, and would be used to pass arguments to subroutines. I carefully explained each instruction to Shima, whose patience was tested as I detailed the XTHL operation. He drew a line under this instruction, and declared:
"No more."
This is why the last 12 instructions were never implemented and why there was room in the instructions set for the 8085 microprocessor's added instructions [23]."
