The original target market was motorolas very lucrative military/space 6800 market, so the chip had to match or exceed the 6800 on all points, including accidental damage. The first version, the 6501 was in fact pin- but not instruction-compatible with 6800, but Motorola had a legal fit and MOS gave up on that idea. The fact that 6502 mainly ended up in Commodore computers was mainly a matter of its lower price. Later the crash in microprocessor prices saddled Jack Tramiel with a huge overpriced inventory which made him outright buy MOS to avoid a repeat performance of that problem.
