The 8080 is a 40-pin package. The Z-80 is a 48-pin package. If I
remember correctly (my life in computers started with the Z-80, really,
since my friend with the Altair when I was in the USAF didn't let me at
the hardware, he knew my [inclined to injure myself] soldering skills).
This generally means that an adapter was needed to plug a Z-80 into a
board designed for a 8080. But I started my real computer career when
computers showed up where you didn't have to count the pins on the CPU,
specifically the TRS-80 (later renamed the Model One). I remember the
first time I looked down into a Model 16 and saw the MC68000 and wondered
why the hell that thing wasn't climbing up the side of the Empire State
Building.
