It looks like the C64 peaked at 40% of market share and that was exceptional (although we see elsewhere the TRS-80 reaching 70% very early on):
Michael Stiel put some work in to resolve competing claims for numbers, and came to 12.5 million C64s over all time. That compares to 5 million in the Apple II series, 2 million for Atari, and 1.5 million for the BBC Micro.
I bet I’ve missed some obvious ones - but any huge sellers missing?
