The C64 vs. Apple II was perhaps the most epic battle of the 8-bit era. Both companies sold millions of machines, yet both nearly went out of business in the process.
Comparing the two machines with the largest software libraries of the 8-bit era is a bit difficult, but that’s what makes it fun. The two machines are similar enough that some people ask if the Commodore 64 was an Apple product. The answer is no.
As a weird aside, it was possible, with a Mimic Systems Spartan, to turn a C-64 into an Apple II. Not many did, but the reason why is another story.
